Are there any plans to leverage or ask the collaboration of any other existing open source implementations? Most important how is the project going to avoid reinventing the wheel and learn from other blockchains? For example Ethereum, Bitshares (Graphene) or the new Enigma by MIT.

I'd also like to know about how existing projects could possibly contribute either existing code (such as the graphene toolkit of the `fc` library) or lessons learned (https://bitshares.org/blog/2015/06/08/lessons-learned-from-bitshares-0.x/#technology-lessons) ..
xeroc
2016-02-24 14:34
It seems there are quite some ideological differences in the parties involved and in the case of Cryptonomex, we are very uncertain as to whether it makes sense to put man power into dealing with politics in hyperledger ..
jmlubin
2016-02-24 14:34
Hey @aeron.buchanan. Great to see you in here.
juanblanco
2016-02-24 14:46
@xeroc it should not be any ideological differences as this is a linuxfoundation project, obviously its usage later on can vary
juanblanco
2016-02-24 14:48
but I understand the man power issue, but I assume they will sponsorship by the parties involved
juanblanco
2016-02-24 14:49
nothing is free is it?
xeroc
2016-02-24 14:49
Is the idea behing hyperledger to have one standard tech to "rule them all" .. or is the idea to have a set of technologies standardized?
juanblanco
2016-02-24 14:50
I am hoping for the latter, as the first one will obviously not work
juanblanco
2016-02-24 14:51
but lets see what other people here say
xeroc
2016-02-24 14:52
yhea .. that is my impression as well .. If they went for the former I see no reasons at all why Cryptonomex should join .. for that we have learn to many lessons and improved too much over our mistakes to neglect it
juanblanco
2016-02-24 14:55
yes that will be nice, lets see if Ethereum can contribute the EVM
juanblanco
2016-02-24 14:56
@mdolan any thoughts about this?
mdolan
2016-02-24 15:00
I’m not the decision maker here. Needs to be a community discussion and someone needs to do the work… we don’t dictate what the community should create. I did talk to a team that came from Eth yesterday and they are planning to engage and contribute. I’ve not spoken to anyone from Eth Fndtn but happy to - I don’t have any contacts... Not sure if that’s what you’re asking...
juanblanco
2016-02-24 15:01
well I am not mentioning just Ethereum, all blockchains in general
juanblanco
2016-02-24 15:01
@xeroc is obviously from Graphene / Bitshares
juanblanco
2016-02-24 15:01
you have Enigma from MIT
juanblanco
2016-02-24 15:02
you have very simple chains like openchain (for private)
juanblanco
2016-02-24 15:04
and more...
juanblanco
2016-02-24 15:04
so my hope is for this project is to unite the best and get the best
juanblanco
2016-02-24 15:05
and create an standard for everyone
juanblanco
2016-02-24 15:07
not discarding of course the current contributions by IBM, Ripple, Digital Assets and Blockstream
mdolan
2016-02-24 15:07

mdolan
2016-02-24 15:07

2016-02-24 15:08
I think once there’s a base code it’s easier for others to see how they would like to work together
mdolan

just my opinion though…
juanblanco
2016-02-24 15:09

xeroc
2016-02-24 15:09
the foundation is essential since it gives the direction whether to have high flexibility or scalibility .. can't 'easily' have both
juanblanco
2016-02-24 15:09
and see if they want to collaborate
xeroc
2016-02-24 15:10
so we need benchmarks first so we can compare differrent protocols and implementations
juanblanco
2016-02-24 15:10
yes performance / scalability / privacy is the hardest
juanblanco
2016-02-24 15:11
and development friendly
juanblanco
2016-02-24 15:11
smart contract creation, interoperability, versioning, discovery
juanblanco
2016-02-24 15:14
but I agree on the overall evaluation of existing blockchains, selection and invitation process if they are not already collaborating
hkchai
2016-02-24 15:15
maybe we can capture a list of key considerations/learnings from existing blockchains?
xeroc
2016-02-24 15:15
you could offer different privacy "modes" on the same chain .. but you can't have different performance and scalability modes ..

Maybe a good starting point could also pin down The usecases wanted and then have a look what technology could be used and what needs reinvention. If one takes all existing technologies and picks what seems best risk is one creates a technology shake without clear vision, what this blockchain should really add to the landscape. Question to be answered could be eg is hyperledger supposed the best blockchain when it comes to XYZ. Starting from there could also avoid ideological discussions on technology approaches.

I believe in general all blockchains try to achieve the same: scalability, performance, privacy, smart contracts, data storage (as per ipfs) , consensus validation, identity, interoperability between contracts and / or other chains. Whilst most of this are none functional requirements, but the blockchain is the infrastructure. Use cases will further validate these needs or extra requirements. So what is the scope, what is needed and what is out there. To develop something faster reuse and involve what it has been already develop, don't reinvent the wheel.
alexkane

juanblanco

Yes to me the vision would be to be the best and the standard, but embracing collaboration. If not it will enter a race that it will never be won.
juanblanco
2016-02-24 21:51
At the moment in my opinion we many chains that excel at different things but not all due to lack of collaboration. Example Ethereum smart contracts development, bitshares performance..
juanblanco
2016-02-24 21:53
But work is carried on both camps to bring the others functionality.

I think benchmark design should not be priority at this stage.
I definitely back the idea of modularity. I would suggest we start from the top and design a "consensus platform framework" which, in an extensible way, provides the capability for the main use-cases. The "consensus engine" and security design can then be swapped out as advancements are made. With current blockchains, the prevalent approach necessarily combines these two aspects, which has blurred our nomenclature somewhat unhelpfully.

@xeroc and @juanblanco to your question regarding contribution and engagement of other open source projects, all are welcome, whether they have joined the Hyperledger Project as members or simply wish to participate as individuals, to contribute to the technical development and discussion. We have had a call for proposals out for a couple weeks, now and there were four who answered that initial call, and a couple others that are still working their way through their internal processes to open source their code.
xeroc

the call itself predates the formal launch and was originally made verbally in one of the formation calls, and then shared on the blockchain-formation mailing list. We have also been discussing it on the hyperledger-tsc and technical-discuss mailing lists since the formal launch.

@basler: by my understanding, the answer is yes. But my concern is how many containers can be run on obc peer, since each chaincode will lunch one container on the peer.

2016-02-26 10:00
@basler: my understanding is primarily to provide isolation from the OBC peer. On the TSC call yesterday, the subject of containers came up and my take away from that was that alternate container solutions should be possible from an architectural perspective. I believe the approach being taken by the project is to make components interchangeable wherever possible.

How “locked down” are the docker containers in OBC? Can chaincode make external network connections? eg API calls to external services outside the OBC?
xeroc
2016-02-26 12:42
not that I fully understand OBC .. but if those containers are part of the blockchain protocol .. than it is a bad idea to poll outside sources since they could render a formerly valid transaction/block invalid at a later time
naddison
2016-02-26 13:05
I was thinking of use cases like: 1. to get data external data as part of a smart contract. eg stock price. 2. to do external service calls. eg sanctions check 3. to act as an eventing mechanism to systems outside the OBC. eg notify customer of new transaction
juanblanco
2016-02-26 13:07
if you get external data, that might change so it will invalidate consensus.
juanblanco
2016-02-26 13:08
oracles ie.. notifications etc should be driven by a transaction
juanblanco
2016-02-26 13:09
that is part of "external" bl which interacts with the chain
juanblanco
2016-02-26 13:09
now...
juanblanco
2016-02-26 13:09
an smart contract could react of an event raised by another contract on the chain
juanblanco
2016-02-26 13:10
as this can be part of the consensus
juanblanco
2016-02-26 13:10
-------------
juanblanco
2016-02-26 13:12
the question is if chaincode is deployed through containers how do they interact with each other and limited to interoperability within the chain, together with consensus of state and transaction
juanblanco
2016-02-26 13:13
but I don't know much so somebody can correct me / guide me
naddison
2016-02-26 13:45
Ah, I get it now. The validating peers will run a slightly different times hence the external service calls can have difference data which will throw concensus

@naddison: also .. you need to be sure that the external service provides the same data EVERYTIME you need to replay the whole blockchain to get to your most recent database state
naddison
2016-02-26 14:30
thanks @xeroc. next dumb question, when would you need to replay the whole blockchain? And what exactly is a reply? Surely it’s not running all chaincode since the genesis block
basler
2016-02-26 14:39
@gengjh: yes for isolation or deployment?
basler
2016-02-26 14:39
@carmania: The problem is that Linux container is not that isolated, e.g. shared kernel
xeroc
2016-02-26 14:43
@naddison: replaying is EXACTLY rerunning every thing since genesis block .. only that way you can be sure that your local database state is consistent with everyone else
xeroc
2016-02-26 14:44
you can though surely do some optimizations here and there and assume that if the blockchain is way longer than the currently block that you replay .. that you don't need to re run everything but can assume a degree of consensus on it ... similar to checkpoints ..

bryce
2016-02-27 02:29
I think the concept of inclusion of external data falls more under “best practices” than something that should be deliberately codified. One can easily envision a market for a number of distributed ledgers which do little else but serve commonly consumed data in a format suitable for bootstrapping oracles.
kobigurk
2016-02-27 03:11
I was too wondering about the "locked down"ness of these Docker containers. I'm usually a fan of the approach of feeding external data as transactions when necessary, but here I think that in some use cases it's not as important to be replayable as it is in Ethereum, for example. causing all external data to only be inserted as transactions might be counter-productive. having a system that provides a point-in-time consensus about something would be beneficial

Wrt to an implementation adoption vs reinventing, how does an examplified cpp lang approach sound
Where the core mission would be to draft and evolve a standard while blessing a single implementation targeted for correctness only and encouraging other implementations to claim an edge on security, performance, cutting-edge standards adoption, interop, support etc (much like we have msvc, clang, gcc, Intel cpp, etc) it's a much more vibrant approach imo.
kendagor
2016-02-29 16:43
The correctness implementation ought to start from scratch so that the next generation experts for the community can learn from it instead of dissecting an optimized implementation that's not trivial

@alexkane & @cmickeyb -- Re: [technical-discuss] Example Use Case: Music Copyrights:
ConsenSys has worked closely with Imogen to develop the Ujo Music Prototype. You can examine the Solidity (Smart Contract) code here: https://gist.githubusercontent.com/simondlr/0e0ca655bd13c1dad072/raw/507c39a798c93f73048484a4c3e40cc51488a5b1/TinyHuman.sol
This smart contract is deployed to the Ethereum public network and has been invoked hundreds of times by consumers who desire to buy Imogen's music. This a real "in the wild" smart contract use case example.
We at ConsenSys continue to explore how smart contracts can power the future of digital rights managements with various clients & stakeholders. The power of an Ethereum-based architecture allows for the rapid deployment of these types of use cases.

Write smart contracts in your preferred programming language.
kendagor
2016-03-01 02:34
@jgarzik Thanks for the link, I'll certainly check it out. I, however, was addressing the core Hyperledger mission where, from my understanding, there's or was a discussion on the approach to take for laying down the first lines of code for the project.
I'm suggesting that the Hyperledger project adopt creating a standard as it's core mission and lay down fresh code for a platform only to prove the end-to-end correctness of the standard. From there onwards other forks, modifiers or fresh standard implementors can pick an edge, be it performance, security, choice of smart contracts vs utxo models, and so on.
I don't believe initiating a production system approach will check-off every conceivable best approach and eventually there may be a point down the road where idea factions will make a hard divergence and that would appear to be a failure in a global mission.
A standards approach with a correctness implementation will help nurture future experts while in the near term encourage various irreconcilable objectives to still gravitate towards a common Hyperledger mission. Various platform approaches can compete on security, performance, x vs y etc but yet interop (protocol, api, who-knows-what) -- surely at least have the same agreement on a standard.
I only mentioned the cpp standard as an example of how a mission can realistically survive for decades yet still be relevant and even thriving because there are various implementations that push each other onwards. Hyperledger could go that route and possibly do some things better :)

@kendagor: the Hyperledger project is at its core an open source initiative… we hope that the fabric we deliver will become the de facto cross-industry standard. However, if by standard, you mean that we should be writing a specification, rather than delivering code, then I’d suggest that’s a very different mission than most members understood when they joined
juanblanco
2016-03-01 14:05
@kendagor: I don't understand the idea of starting from scratch either... why reinvent the wheel. Shall the project create everything new? Should we not ask the current experts for the advice? You have the risk of of becoming (as mentioned before) just another blockchain that nobody will use.
joeconyers
2016-03-01 15:23
@igor.lilic: Love the smart contract side of what they did with Imogen but it doesn’t address the wider issue around copyright information(who wrote what and who currently represents whom) delivery and dispute managment which is a huge issue. We deal with 100’s if not 1000’s of databases that slide from truth and are perpetually out of date.
joeconyers
2016-03-01 15:24
Devs and the industry have been approaching this from the artist side which is an incremental move, not a step change. Needs to be approached from composition side - can’t license music(i.e. Make a new Spotify) more efficiently without that information.

@joeconyers: Definitely agree with the fact that there is more work to be done.

igor.lilic

@cbf , @juanblanco yes I did mean the project owning a specification. I know this project will deliver a great platform certainly because of the experts we have. I just believe that unifying around a specification as well will help other implementations have a bona fide checklist of compliance so that we can have a one worldwide platform from many implementations.
As for the reinvention, it was still to drive the standard specification, but being that the arguments for a production-level implementation is very sound because we have great experts, I'm fine with that approach too (having expressed my point :))
In brief I look forward participating however the community goes code-wise. I also hope you'll consider owning a standard specification as well.
To digress a bit, perhaps there might be regulations or other controls in some key economy elsewhere in the world which may make the production-level subject to modification or rewrite to be viable there (cryptographic export/import regulations, anonymity, trade policies, "censorship", etc) that's one of the reasons owning the standard could possibly keep the initiative under the same wing)...
Thanks for your feedback. I hope there's still more to add :)

Ethereum was created with a specific vision in mind. While the arguments presented in the article are correct, it does bear the assuption that Hyperledger will behave similarly from a transactional level however that has not been established.

Hi , I am new to this community just poking my head in for the first time. I am Zach Dexter, CTO of LedgerX. We have received temporary registration from CFTC for our Swap Execution Facility, and have a clearinghouse application in with CFTC as well - if approved, this basically means LedgerX would be a fully-licensed/regulated blockchain clearinghouse. We feel this can help resolve many questions around compliance for blockchain projects. I'll be lurking to figure out how the Hyperledger Project works and I'm excited to be a part of this. Nice to meet everyone!
Also, thanks to whoever has been doing meeting minutes - those have been very helpful.

HI, I just joined. I have a technical question, someone here to answer me?
I'm wanting to see what I can do for the hyperledger project, but I'm not a programmer. I'm having +20 years with Linux in the Enterprise. Broad and deep knowledge of infrastructures with a strong focus on Linux
Able to script a bit in Perl/Python

Here's a non financial use case ... distributed software package management: https://evertpot.com/npm-revoke-breaks-the-build/
shemnon
2016-03-23 16:30
that idea was rolling in my head but I was wondering what need would it fulfill. Apparently this one.
shemnon
2016-03-23 16:31
Also... publishing results of deterministic or validated builds.
shemnon
2016-03-23 16:32
which is really just a very niche case of the tech behind smart contracts but without the token economy.
christophera
2016-03-23 16:45
@shemnon We were working on that as one for first use cases for the #RebootingWebOfTrust project. I was also in discussion at RSA around verified credentials for "eyes on" reputation for code.

To be clear, many conversations were had today with regards to general architecture. The resulting thought, discussion, and experimentation is ongoing – including over fundamental differences in perspectives. We made much progress today on understanding these differences, but the implications remain unclear.
Next steps are to continue discussions regarding interoperability protocols, including adding more detail to the various [new] additions. I'm excited to be having these discussions, but it should be clear that no formal decision has been made with regards to architecture.
mdolan
2016-03-24 01:02
Hmm… ok, I was trying to update the Hyperledger pitch deck with something we can show. If we get that slide from Binh and remove some details would it be possible to get a working version everyone’s ok with at some level? High level is fine for my needs...
jaekwon
2016-03-24 01:02
Maybe hyperledger could endorse more than one architecture. But what’s the point? Who gets to decide?
jaekwon
2016-03-24 01:03
What’s the voting power for each of us, eh. Does what we suggest matter if we’re not in the steering committee?

we were all split up. i walked around group to group. we talked about smart-signatures and crypto-conditions a bunch, and some of us decided that working on standards of data models would be a good idea.
jaekwon
2016-03-24 02:09
Some others might have different takes on it.
jaekwon
2016-03-24 02:09
I talked with IBM folks, tried to find the difference between chaincode and TMSP.
jaekwon
2016-03-24 02:09
That was interesting.
jaekwon
2016-03-24 02:10
As far as I can tell, chaincode is synchronous? And it definitely puts state in the core.
jaekwon
2016-03-24 02:10
Whereas TMSP is asynchronous in pushing txs to the app and deferring decisions on state management to the app.
jaekwon
2016-03-24 02:11
Which makes it easier to integrate with existing systems.
jaekwon
2016-03-24 02:12
Good presence from DAH and IBM. They were hacking on something. I don’t know what came of that, curious to hear from that side.
jaekwon

Oh I remember an early discussion where IBM and DAH were trying to create cross-compatible server/clients.
jaekwon
2016-03-24 02:14
Then there was another meetup afterwards with IBM and DAH presenting their systems to some crowd. I don’t know, wasn’t there.

quick question are people from ripple active here?
igor.lilic
2016-03-24 02:33
@thivankaa: I believe Ripple proposed an architecture but don't have representation at the F2F
igor.lilic
2016-03-24 02:35
IBM/DAH are the only groups who both submitted a proposal and sent engineers to the F2F so their joint proposal is the one with the most legs / where most of the technical work at the F2F is focused
thivankaa
2016-03-24 02:59
sorry what does F2F stand for is it some kind of group or conference? I was wondering if ripple engineers were active on this slack group.

jaekwon
2016-03-24 03:10
that’s basically not true.
jaekwon
2016-03-24 03:15
Blockstream was there. Tendermint was there. We made a proposal on Github.
kelly
2016-03-24 03:21
thanks for the update @martindale
kelly
2016-03-24 03:24
@jaekwon: did tendermint propose a contribution for the hyperledger project?
jaekwon
2016-03-24 03:24
sure, I’m telling everyone I meet at the F2F about this: http://github.com/tendermint/tmsp
jaekwon
2016-03-24 03:25
and telling IBM that we should make chaincode speak TMSP, or, to implement OBC as a TMSP application.
kelly
2016-03-24 03:27
tmsp seems to be the communication and journalling layer right?
kelly
2016-03-24 03:27
or tendermint core rather
jaekwon
2016-03-24 03:27
it’s similar but more general than the chaincode messaging protocol.
jaekwon
2016-03-24 03:30
I don’t know whether IBM’s and DAH’s systems are currently interoperable, but, if DAH’s system doesn’t yet run on OBC, they’ll have an easier time integrating with Tendermint, because it’s less opinionated about whether to handle state persistence.
jaekwon
2016-03-24 03:33
IBM’s proposal is interesting too. It would also be relatively easy to integrate OBC with Tendermint. It would basically make OBC really consensus-algorithm agnostic.
jaekwon
2016-03-24 03:33
So my proposal is this: https://github.com/hyperledger/hyperledger/issues/7#issuecomment-193584684
jaekwon
2016-03-24 03:35
Shemnon comments below that consensus is the most contentious element, and that IBM already has plugability… OBC kinda does, but TMSP does a different kind of job at it.
jaekwon
2016-03-24 03:36
For example, we define a few optional messages that applications may or may not implement. InitChain and EndBlock are optional messages… not all applications need to implement those messages, but, if they do, the application logic can mutate the validator set.
igor.lilic
2016-03-24 03:37
@jaekwon: Don't get me wrong - I want more proposals and discussions
igor.lilic
2016-03-24 03:39
Has 4 proposals listed...Ripple isn't at the event, and Monday morning only DAH and IBM spoke before the break outs; the hackathon objectives as stated on Monday were focused on those integrations and moving the joint proposal forward
jaekwon
2016-03-24 03:40
Cool. Well, we flew over from Canada and San Francisco to have a discussion.
igor.lilic
2016-03-24 03:44
No doubt - didn't mean to sweep your contributions under the table; but to be honest I didn't even know about your proposal (I've been working with the requirements break out). The readme itself seems to be the "canonical list" of proposals..not sure how that goes about being updated
jaekwon
2016-03-24 03:46
I have no idea either.

2016-03-24 03:46

no

2016-03-24 03:52
'elements' are additions to the bitcoin software that are not yet implemented on the bitcoin blockchain

I also got quite confused as to why IBM and DAH got to present their proposals. In the beginning, I thought it was just so that people could get familiar with some chain code, any chain code to start with but when they started integrating the code to the hyperledger github... To be honest, I assumed hyperledger had decided to base its code on the IBM code. if IBM's is not the defacto solution how do you go about integrating or replacing it with other solutions later on?
primrose
2016-03-24 12:30

@primrose: DAH's code complements IBM's with an API to implement workflows in financial services and supplies a non-trivial chain code.
tamas
2016-03-24 13:58
OBC is just a framework (a fabric) DAH brings it closer to a solution platform for financial services

right ok. so the code went into an incubator and not into the hyperledger git! got it. so will the other proposed codelines go into the same incubator? I imagine the plan is that when we've all got some understanding of what the technology is then we try to build the same or different scenarios using this and other chain codes and choose what works best? Assuming there is a plan... or is this jumping the gun a bit because i know there was talk of architecture as well.

One thing this week that we've been punting on is the issue of Identity, ranging from management of private keys and wallets, hardware identity authentication requirements, nature of multisignatures and authorization, privacy and selective disclosure, ui and use case, regulatory requirements, international issues, etc. I've been working with a UN Summit http://ID2020summit.org on May 20th, and a follow on 'design workshop' on the 21st and 22nd. I'm also working with the W3C and OASIS on decentralized identifiers and keys on blockchains. I'd like to identify who is interested in a Hyperledger BOF or WG on this topic, or is interested in participating in the UN Identity Summit. Send email to me at .

Wanted to share details on an interesting conference: The Euromoney Blockchain Forum http://fr.zone-secure.net/19106/184480/?utm_source=TZ_ELE1372_Blockchain_2016
“A programme assembled through conversation and collaboration with leading financial institutions, technology companies and regulators around the world. The Euromoney Blockchain Forum will deliver probing discussions on key over-arching issues such as regulation and KYC, while also examining specific use cases and proofs of concepts across areas such as equities or derivatives trading.”

@cbf: should we discuss tooling on the TSC agenda this week? It looks like the result from last week is the community is getting close to pulling code into the main repo… Not sure we’ve discussed what (if any) infrastructure the group wants to have working.
mdolan
2016-03-29 18:42
Also did anyone document the proposal for the TSC so the group can get started on an approved project? The incubator is going to be difficult to just “move over” with workflows/etc…

Hi Chris et al - Roger Strukhoff here from Altoros. I work for Renat and Andrei as Director of Research and want to grab the whitepaper by the horns and make it hyperledger-centric instead of OBC-repurposed. Any guidance on how I can get started doing this?

to the risk of showing how much of a noob I am, I'd like to know what this dco-bot is about. Who set that up? LF? What purpose does it serve?
kumavis
2016-04-05 03:05
@arnaud: which dco-bot
arnaud
2016-04-05 03:52
@kumavis thanks for making me feel better about not knowing. :simple_smile: I submitted a pull request to the new repo and dco-bot responded requesting for me to "sign-off" with a comment. DCO actually stands for "Developer Certificate of Origin". dco-bot simply is a mechanism asking contributors to certify that they are effectively the contributor. I figured this was it actually, it's a pretty standard practice, but don't know who set it up in this case.

now it is in the hyperledger repo with the name *fabric* and this description: >This project contains the core blockchain fabric code, development environment scripts and documents for developers to contribute fabric code or work on their own applications.

cbf
2016-04-05 13:45
@mdolan: said you guys had a process for checking that DCO signoff is included in any PR - my little bot only checks the initial PR. We need something like gerritt or jenkins to actually check that the signoff is included in the PR or one of the ensuing comments
ry
2016-04-05 13:49
the workflow we use for other projects is part of Gerrit (requiring signed commits). the process of getting the ability to post the patches requires signing the contribution agreement. I’m not sure how that would work with github. I’ll talk to other project admins and see if we have something I’m unaware of.

2016-04-05 14:08
@ry for the CLA system or for the DCO signed-off-by requirement?
ry
2016-04-05 14:08
Gerrit is the enforcement mechanism for signed-off-by. As part of getting an LFID you have to sign the agreement
kelly
2016-04-05 14:09
@cbf: I missed the end of last week's TSC -- I thought the decision was to incubate the IBM/DAH code as _one_ of the proposals to get hyperledger started
ry
2016-04-05 14:09
so you sign the agreement when you get the account, then you sign each commit to assert you authored it
kelly
2016-04-05 14:09
now it is in the hyperledger repo with the name *fabric* and this description: >This project contains the core blockchain fabric code, development environment scripts and documents for developers to contribute fabric code or work on their own applications.
kelly
2016-04-05 14:09
Did I miss something at the end?
arnaud
2016-04-05 14:09
@kelly, I don't think you missed anything, it is an incubator
kelly
2016-04-05 14:10
oh ok, the naming seems a bit misleading
arnaud
2016-04-05 14:10
the description reads "Blockchain fabric incubator code"
kelly
2016-04-05 14:10
will future proposals be called fabric2, fabric3, etc?
arnaud
2016-04-05 14:11
but I agree the readme should reinforce that
arnaud
2016-04-05 14:11
I don't know that, don't know how the name was chosen
kelly
2016-04-05 14:12
gotcha, ok thanks for the info
kelly
2016-04-05 14:12
I had always seen it called IBM/DAH proposal
kelly
2016-04-05 14:12
so wasn't sure if something had changed
arnaud
2016-04-05 14:13
well, it's no longer just IBM-DAH proposal, it's now an Hyperledger incubator project
kelly
2016-04-05 14:13
right
arnaud
2016-04-05 14:14
but I think Christopher Allen volunteered to provide some text that would be used to clearly state what the status of the project is
mdolan
2016-04-05 14:14
@kelly I thought fabric was generic enough… nothing really more than that.
kelly
2016-04-05 14:14
yes I recall @christophera reinforcing that it should be clearly marked incubator
arnaud
2016-04-05 14:14
@cbf dco-bot confused me in that it provided no guidance whatsoever as to what info was expected in the sign-off
kelly
2016-04-05 14:14
@mdolan: thanks Mike, makes sense, I'm just wondering how we'll name future proposals
mdolan
2016-04-05 14:15
yeah, would be helpful to come up with a plan for naming at some point
kelly
2016-04-05 14:15
e.g. if there is a repo in there called 'blockchain' that would be a bit deceptive
kelly
2016-04-05 14:15
so need some way to refer to the different proposals
mdolan
2016-04-05 14:15
On the first TSC call I mentioned coming up with a template
christophera
2016-04-05 14:15
@cmickeyb and I are working on README about what incubation means
mdolan
2016-04-05 14:16
for project proposals, the templates we use normally include a name for the project
arnaud
2016-04-05 14:17
@christophera As I said on the call last week I think we should fix the definition in the project lifecycle document if needed and link to that definition
arnaud
2016-04-05 14:18
shemnon
2016-04-05 14:27
I think what @kelly is getting at is that the naming convention implies it is mature than it is. I.e. a git repo that is not mature should be named as such and movement from incubation to mature involves a repo name change.
shemnon
2016-04-05 14:28
That is what I liked about the hypwrledger-incubator group, it made it clear that those repos were not mature.
shemnon
2016-04-05 14:29
Mature according to the life cycle doc.
arnaud
2016-04-05 14:31
@shemnon: changing the name of the repo is a real pain, it has ramifications in the whole code and documentation as we are seeing from the current move
arnaud
2016-04-05 14:31
there are other ways we can communicate the state of the repo
shemnon
2016-04-05 14:33
Apache does such movements for every project. The fact it has some extra level of effort imho adds a good check to see if it is ready.
shemnon
2016-04-05 14:35
I agree with what @kelly is implying with his question:, the repo and naming convention implies it is mature and ready and the settled solution when it is not.
shemnon
2016-04-05 14:36
Despite what the readmes say. Those don't show up in commit streams that often.
shemnon
2016-04-05 14:36
It may become the mature ready settled solution, but it is not that today.
arnaud
2016-04-05 14:37
I don't think anybody claims otherwise
simon
2016-04-05 14:37
I suppose migrating the repository itself isn't too big of a deal. However the way go handles imports means that external projects that may be already underway (and which nobody knows about) will have to do the same. Distributed (compounded) pain
shemnon
2016-04-05 14:38
When we have a mix of mature and incubated projects we will see this issue again if we don't provide some name based indication.
arnaud
2016-04-05 14:47
you can edit a post after you sent it
shemnon

Hi all, FYI, I had an outstanding proposal on OBC for a tooling enhancement…. I just “rebranded” it to the HL tree, which you can read about here: https://github.com/ghaskins/hlcc
ghaskins
2016-04-06 19:43
i still need to figure out what the HL/LF official proposal mechanism is and follow that, I just wanted to get eyeballs on it ASAP

@ghaskins: use the proposal I submitted last week as a template https://docs.google.com/document/d/1XECRVN9hXGrjAjysrnuNSdggzAKYm6XESR6KmABwhkE/edit

@cbf: awesome, thanks
ghaskins
2016-04-06 21:03
right now, the code isnt ready for merge consideration, its still WIP….is a WIP like proposal process covered in there already?
ghaskins
2016-04-06 21:03
or would that have a different workflow
cbf
2016-04-06 21:04
yes, would classify this as an incubation proposal

specifically: "@ghaskins could you also change the location +NAME=openblockchain/baseimage to +NAME=hyperledger/baseimage” from @binhn
ghaskins
2016-04-06 22:18
but it seems someone is already managing the /hyperledger namespace on dockerhub, so I wont be able to rebrand the OBC images until that is resolved

Question regarding OpenBlockChain. For testing purposes, I have created a tokenized assets application atop OpenBlockChain. I used ibm-blockchain-js to access the chain. It works as expected. But it’s missing the ability to display previous owners of an asset, which is important for this type of application. I need the state history for that. Is there a way to get that currently? Or if that's not yet implemented, what is the wisdom on how that should be derived?
chetsky
2016-04-07 02:25
Juan, think about how you would do this in a real database
chetsky
2016-04-07 02:25
in a real database, you would NOT have access to the tarn-log, right?
chetsky
2016-04-07 02:25
tran-log
chetsky
2016-04-07 02:26
it's true that in some blockchains, they give access to the tarn-log. E.g. in BTC. But that's b/c they don't understand databases.
chetsky
2016-04-07 02:26
Such access means that you can never prune the log, and cannot bound the memory working-set of the application.
chetsky
2016-04-07 02:26
all that's a way of saying, I think you should not expect tarn-log access.
chetsky
2016-04-07 02:26
HOWEVER< there is a standard way of solving this problem
chetsky
2016-04-07 02:27
Basically, you want to have a historical table.
muralisr
2016-04-07 02:33
And there are access related issues in progress (eg 961 , 845 etc ) that should help with that

@chetsky: pruning of transaction log is addressed in Satoshi's whitepaper, the first thing you should read before critizising Bitcoin. https://bitcoin.org/bitcoin.pdf Section 8.
tamas
2016-04-07 08:17
It is the most important by-product of the UTXO model, that transactions that are referenced can be removed from the transaction log while preserving audit-ability.

@simon Pruning is optional and can be selective by any external criteria. E.g. a node might decide to keep entire log for transactions it is involved in, while pruning all unrelated and already referenced transactions.
simon
2016-04-07 10:56
makes sense
chetsky
2016-04-07 11:17
Tamas, this is true for -bitcoin-. It's true b/c in bitcoin, inputs are -consumed-.
chetsky
2016-04-07 11:17
but in OBC< they're -not-
chetsky
2016-04-07 11:18
So the possibility of refernce to past trans in the log intrinsically implies no ability to prune.
chetsky
2016-04-07 11:18
even in BTC, if you allow reference to STXOs, you cannot prune without changing application behaviour
tamas
2016-04-07 11:24
@chetsky: yes it is true for Bitcoin but not because - as you said - they would not understand databases. yes it is not true for OBC, maybe because they do not understand blockchain?
tamas
2016-04-07 11:26
jokes by side. I think OBC misses an important design decision here. We will I hope fix.
chetsky
2016-04-07 11:33
@tamas we can disagree on this, but I claim that what @juan is asking for, is arbitrary historical look-back at trans. In BTC it would b e"please show me all trans over $10000, paid by chet". BTC's log-pruning is precisely the same as any reclamation in a log-structured store -- trans whose results are superseded, may be removed. But those results aren't superseded for @juan's purposes.
chetsky
2016-04-07 11:34
at least, that's my claim
simon
2016-04-07 11:35
yea, the decision on pruning here is dictated by the application
tamas
2016-04-07 11:36
What is reclaimed is not defined by Bitcoin, rather how you reclaim while preserving audit-ability.
simon
2016-04-07 11:37
and given that the application here is the chaincode, which needs to execute deterministically, this implies that pruning needs to be done consistently across all nodes
simon
2016-04-07 11:37
or, if you don't want to limit yourself that way, have the chaincode maintain its own history state
tamas
2016-04-07 11:38
@simon I disagree with the notion, that the application was defined by chaincode. Chaincode is a building block for the application, quite similar to stored procedures.
simon
2016-04-07 11:41
yes, that's semantics of what is the application. in general I agree that the application exists outside and inside the chaincode, and these components communicate via the fabric
simon
2016-04-07 11:44
what I wanted to get to is that for a given chaincode, all nodes need to prune their logs the same way. Now you could create some complex interface that allowed the chaincode to configure this pruning for its own data, or you could just tell chaincode developers that they have to persist their own historical data.
simon
2016-04-07 11:46
and I guess that's where your preserving auditability point comes in - in pure UTXO, the data structure retains auditability of all history items (those that have not been pruned), while chaincode copying data to a history "table" loses this direct data-based auditability
tamas
2016-04-07 11:50
I do not see why nodes using same chaincode would have to prune same transactions. Bitcoin's script is a chaincode, as we demonstrated on the Hackathon, the decision which tx can be pruned is not linked to that.
jamie.steiner
2016-04-07 11:52
I think what is required for "auditability" may vary a lot for different parties in different jurisdictions. To me, it seems inevitable that some off-blockchain persistence of data or events will be required.
tamas
2016-04-07 11:54
One of the selling points of a blockchain is audit-ability. The blockchain has to hold proofs, not necessarily the data itself. The block chain storage can however be pruned (trimmed) of transactions you do not care, such that these deletions do not break the proofs.
simon
2016-04-07 11:54
tamas: yes, because you store the UTXO information as state
simon
2016-04-07 11:55
but doesn't that already break the simple auditability?
tamas
2016-04-07 11:56
UTXO is implied by the log even if log is pruned. UTXO storage is merely a cache if it exists at all.
jamie.steiner
2016-04-07 11:57
As a thought experiment, are there categories of events that must not be recorded in the blockchain, but must be auditable later? what about something like failed transactions: you need a record of why they weren't executed, or similar.
simon
2016-04-07 11:58
right. in fabric, you can only prune a prefix, but not the sides (merkle tree for UTXO) of the blockchain
simon
2016-04-07 11:58
because the UTXO transactions are opaque data in the chain

@jamie.steiner: This could be accommodated. It is very well possible to have a "Raw Ledger" (RL) which would contain, e.g., information about failed transactions and such a RL would be made auditable. Blockchain (the "real" ledger) could be then seen as a filtered version of the RL, once system-level events and failed-transactions are filtered out.

@chetsky @tamas @simon @jamie.steiner: thanks for the reply and discussion! A few thoughts:
1) In my tokenized assets application I only need the history of a single chaincode, not the entire blockchain. I think this is a very common case.
2) In my view, auditabiltiy is pretty much the whole point of the blockchain. The Merkel tree provides proof in plain sight of all the participants of the derivation of the current state. Thus everyone can agree on it. Other functions layer atop this one main function that the Merkel tree provides.
3) I haven't thought this through completely, but I've been mulling over whether it would be useful to have some kind of heirarchical auditabiltiy, where a useful proof can be performed for only the subset of the tree relating to the interests of a subset of participants. Thus these participants can convince themselves of the correctness of their state without needing to audit the entire tree. And without looking into everyone else's business.
Consider an architecture where each chaincode has it's own Merkel tree. The state transitions for that chaincode could be audited without reference to transactions or states of other chaincodes. Thus a chaincode's entire history could be derived, rather than relying on a saved DB.
Hashes on this chaincode Merkel tree would be posted to the main tree. In fact, the main tree could consist solely of hashes without any transaction content. Fully proving any chaincode state up to the current blockchain hash would require only this relatively compact global tree.

@juan: Good question. We pondered that same idea (a merkle tree per chaincode) a long time ago, but I believe it was discarded due to potential performance concerns. I’m open to exploring again though. @chetsky usually challenges the need for a merkle tree. If everyone has the same transaction log via the blockchain, (and we know the contract is deterministic) why would you not trust your node to have the correct state?
simon
2016-04-07 17:16
i guess it is about other nodes trusting the data they get from you
simon
2016-04-07 17:17
i.e. how could a new node trust the state you hand over, if that state is not part of the block chain?
simon
2016-04-07 17:17
with mvcc, that may be different, and a node could just play forward all deltas (slow)

I definitely urge WG chairs to create advance agendas and call information and at least send to the appropriate email list. I know it can be repetitive, but it is best practice from other standard orgs. Event notifications require multiple channels.

@binhn: @ghaskins: As fabric is only one incubator project, and there will likely be others, I think we need a way to carve out namespaces on docker, vagrant, launchpad, etc. for multiple incubation projects (if they are going to be in a hyperledger namespace). For example hyperledger/fabric. Thoughts?

@pjholmes: overall agree, though I struggle to understand where you see the docker/vagrant/launchpad stuff being broken out from the current fabric incubator

possibly the vagrant part, as that is what OBC had originally too (obc-peer.git and obc-dev-env.git)

but it seems the docker parts are somewhat integral

So as well all come together to collaborate in Hyperledger, we each bring with us words and languages from our communities of origin that are often different than that used by other communities. Some words are completely different, but in some cases there is the equivalent of "100 words for snow" problem where one group bundles the complexity into a single word or phrase, whereas other expose the complexity by having different words for everything.
ghaskins
2016-04-07 19:26
wonders if atlas/dockerhub have a hierarchical namespace
christophera
2016-04-07 19:27
I personally found quite a few differences in language during the F2F, as well as different underlying mental models. For instance the words verification, validation, and confirmation where not all used the same way. What were the words or models that you found you had to learn or translate for others?
christophera
2016-04-07 19:30
Some other words — I interpreted "incubation" a different way than it appears to be how we use it. Even words that we think are in common like decentralize appear to have some subtle differences from the different communities that are collaboration.

@ghaskins how about "proposal1" or "incubated1"
ghaskins
2016-04-07 19:55
opps, sorry @jyellick crossed messages, heh
ghaskins
2016-04-07 19:56
@middleton: not a bad idea to incorporate status, though might be helpful to have more context like project name (e.g. hyperledger/proposal1-fabric-baseiamge
ghaskins
2016-04-07 19:56
as I suspect there will be other repos that arent strictly “fabric” proposals
ghaskins
2016-04-07 19:57
for instance, that toolchain I am working on could conceivably be something like hyperledger/hlcc…i would imagine other proposals might be similar where they are adjunct to the fabric

Hi All, what was the issue with the hyperledger namespace on docker/docker hub?
dan
2016-04-07 20:07
I don't believe Digital Asset controls it but happy to look into it and relinquish, if so
ghaskins
2016-04-07 20:12
@dan: in this context, I was asked to rebrand some of the obc stuff we had: e.g. https://atlas.hashicorp.com/obc/boxes/baseimage to https://atlas.hashicorp.com/hyperledger/boxes/baseimage
ghaskins
2016-04-07 20:13
we also had this dockerhub https://hub.docker.com/r/openblockchain/baseimage/, but couldnt move it over to “hyperledger” because the org already existed
ghaskins
2016-04-07 20:13
not sure who controls it
ghaskins
2016-04-07 20:14
as a secondary discussion, we are also trying to sort out the best name under the hyperledger namespace, as “baseimage” is too generic when there might be other proposals under the hyperledger umbrella

ghaskins

ok
ghaskins
2016-04-07 20:16
on the atlas front, i created the org and assigned ownership to @sheehan. I’ll leave it to the TSC to sort out additional roles

Until Docker understands machine architecture, I would like to see all Docker images tagged with their architecture, e.g., x86-fabric-baseimage. ARM, POWER, and Z are all first-class architectures, there’s more to the world than X86.
ghaskins
2016-04-07 20:18
@bcbrock: excellent point, ill incorporate that into the patch being worked on

ghaskins
2016-04-07 21:16
yeah, i understand @middleton’s point about the incubator/proposal status, but I am inclined to vote for “hyperledger/fabric-baseimage”…we already have precedent for that namespace in both github and slack

However, I'm not sure give the interface if some people may be confused and not realize the time is 2pm EDT. So if you are interested in attending but were confused on time zone, go back and edit your Doodle answer. Thanks!

I check the project code and seems there’s no Dockerfile to build an image, anyone has plan to create one? Saw lots of instructions in several docs and files.
ghaskins
2016-04-08 13:26
What is it you are trying to do?
ghaskins
2016-04-08 13:27
most of the Docker stuff is built dynamically based on yaml configuration, so you might not see a literal “Dockerfile” if you search at the filesystem level
ghaskins
2016-04-08 13:28
so, theres a chance what you are looking for is already available
baohua
2016-04-08 13:30
great, then i guess we should have one image that can serve as various roles with different yaml config.
baohua
2016-04-08 13:30
that will make everyone to get started very quick and simple
tuand
2016-04-08 13:31
@baohua are you talking about the hyperledger/fabric code ?
baohua
2016-04-08 13:32
yes, i notice that it mostly is easy to try with vagrant, but no simple dockerfile to have a runnable container :simple_smile:
tuand
2016-04-08 13:34
look at the examples in fabric/consensus/docker-compose-files or in fabric/bddtests
tuand
2016-04-08 13:35
you will still need vagrant but these docker files take care of most of the config needed
baohua
2016-04-08 13:36
yes, i found them, thanks tuand!
simon
2016-04-08 13:36
maybe we should move the peer build via test into a righteous dockerfile?
baohua
2016-04-08 13:37
i suggest so, people get used to pull image and have a quick try.
tuand
2016-04-08 13:40
there's 2 dockerfiles one for the fabric server in consensus/docker-compose-files and one for the member services server in /membersrvc
tuand
2016-04-08 13:40
@boahua, you're thinking about docker images though
tuand
2016-04-08 13:40
sorry typo @baohua

hi! thank you all for your support here!
I wanted to ask a question regarding the CA. Where should anyone designing a BC network put it? The CA needs to run in someone's server, if all the servers are owned by non-trusted peers where should this CA run? Having in a server where some peer could "reach" it doesn't make the whole BC vulnerable?

@mcrafols: @sheehan For now it is a temporarily standalone service to work out the security and identity flow. It will be decentralized as a system chaincode. New member registration is submitted as an Invoke Transaction to the bc network.

I've not heard back from @philipdesautels about the putting the identity meeting on a calendar, and how to get the webex to work. Who else from Linux Foundation can we talk to about this?
We have selected next Friday, April 15, 2016 11:00 AM – 12:00 PM (PDT) / 2:00 PM - 3:00 PM (EDT) as the final option(s) for the Initial Hyperledger Identity WG call. 14 said they could make it, 4 could not.

Hi, allow me to ask some questions:
1.-If my network had all the necessary VP and users from the beggining and the CA wasn't needed to enroll any other user after the initial set up, could the CA be shut down after the set up without affecting the correct behavior of the network?
2.-How can new VP be added to the network if in the set up phase of the other VP the N and f parameters are already determined?
3.-Variables stored by some CC A can only be accessed by the same CC A? So if a CC B wants to access variables from CC A it has to query/invoke CC A functions?
4.-Is there any restriction on query tx sending invoke tx referencing other chaincodes?
mcrafols
2016-04-13 07:57
Thanks in advance!
simon
2016-04-13 09:27
(2) dynamic reconfiguration - is in the works; doesn't work right now
simon
2016-04-13 09:27
(3) correct, state is separate per chaincode
simon
2016-04-13 09:28
(4) i don't think that a query can send an invoke - what would that even mean?
mcrafols
2016-04-13 09:32
well, in the chaincode api it says that any chaincode can call any other chaincode with InvokeChaincode and QueryChaincode
mcrafols
2016-04-13 09:33
it doesn't explain any restriction on how this two functions should be called
mcrafols
2016-04-13 09:33
so what if I call InvokeChaincode from a query transaction?
mcrafols
2016-04-13 09:35
Let me also explain why I want this: I want to register whenever a user reads a variable (which will be a document).
mcrafols
2016-04-13 09:37
And as invoke transactions cannot return WS variables (can they?) this is how I thought I might implement it, query calling invoke (which wouldn't do anything).
simon
2016-04-13 09:43
i see
simon
2016-04-13 09:43
no, not possible
simon
2016-04-13 09:43
because queries only go to one replica, but invokes have to go to all
simon
2016-04-13 09:44
is there a reason why you want to register this?
simon
2016-04-13 09:44
i mean, publicly, forever recorded information?
mcrafols
2016-04-13 09:46
well the use case involves legal contracts and although not essential, knowing when each network user reads the document can be relevant
mcrafols
2016-04-13 09:47
so invoke transactions can't return variables
simon
2016-04-13 09:47
you could make it a two step process
mcrafols
2016-04-13 09:48
but why can't a query tx call another CC invoke?
simon
2016-04-13 09:48
because a query only goes to one replica, and an invoke goes to all
mcrafols
2016-04-13 09:48
I could solve the problem from the application level
simon
2016-04-13 09:48
you could have the application first "register" the read
simon
2016-04-13 09:48
and only when the read has been registered, it can query the document
mcrafols
2016-04-13 09:50
I think that could work
mcrafols
2016-04-13 09:50
just for the sake of the argument
mcrafols
2016-04-13 09:51
when a user makes a invoke transaction, does the user (or wallet service) send the transaction to all VPs?
simon
2016-04-13 09:51
yes
simon
2016-04-13 09:51
well, it goes to one VP
simon
2016-04-13 09:51
and that one broadcasts it
mcrafols
2016-04-13 09:51
the broadcast is internal
simon
2016-04-13 09:51
yes
mcrafols
2016-04-13 09:52
so now, why not invoke from a query tx?
simon
2016-04-13 09:53
because a query is a readonly operation
simon
2016-04-13 09:53
you actually want an invoke that can return a value
mcrafols
2016-04-13 09:54
not really, if an invoke could return a value that would be awesome, but you said it is not possible
mcrafols
2016-04-13 09:54
from the query tx I just want to invoke some function that will do nothing and return nothing but will get registered
simon
2016-04-13 09:57
but that is not reliable - an incorrect replica could just return the value, but never perform the invoke
mcrafols
2016-04-13 10:01
yes, the application waiting for the invoke to be registered ensures that this can't happen (returning value but not registering tx).
mcrafols
2016-04-13 10:05
if a invoke tx A calls and invoke tx B wouldn't this last invoke tx B be sent by all VP that execute invoke tx A, thus having the invoke tx B replicated many times (as all transactions that arrive to a VP are broadcasted)?
simon
2016-04-13 11:12
no
simon
2016-04-13 11:12
the calls happen locally
simon
2016-04-13 11:12
they happen in the same transaction
mcrafols
2016-04-13 11:16
don't they happen when the invoke tx is executed (and they are executed by all VPs)?
simon
2016-04-13 12:04
yes, the invoke executes in each VP, and when there is a call to another chaincode, that VP will execute the other chaincode
mcrafols
2016-04-13 13:05
oh, then this second invoke transaction won't go through the consensus protocol and will be committed right after the 1st invoke?
simon
2016-04-13 13:44
it will be committed as part of the same transaction
mcrafols
2016-04-13 13:59
thanks! then if it behaves like this, it doesn't seem that a query transaction doing an invoke will work as it can't register with the same transaction
mcrafols
2016-04-13 14:37
Does anyone know the answer to this question:
If my network had all the necessary VP and users from the beggining and the CA wasn't needed to enroll any other user after the initial set up, could the CA be shut down after the set up without affecting the correct behavior of the network?
It is kind of very important as I can't give the control of the CA to any of the distrusting network actors and actually probably for many use cases with permissioned networks the CA is not needed as no VP will be added for sure.

About legal. We are trying to use hyperledger fabric for automated execution of contracts, and the way we plan to handle the legal stuff is to embed the legal boilerplate into the chaincode. We've already gotten several contracts written and in production, and all we need to add them to hyperledger is to write a javascript execution engine.
joequant
2016-04-14 17:41
As far as actual legal execution, you want to isolate in the chaincode. If you try to push the legal into the fabric, you'll never get anything working.
joequant
2016-04-14 17:43
Compliance is a different issue. The big headache we've had so far is that we had to have some of our smart contracts approved by the HK Police (which regulates money lending) as part of a court hearing. We had to go to paper. (i.e. convert the source code to PDF, run some screenshots, print it out)
buhrmi
2016-04-14 17:44
a javascript engine written in chaincode?
joequant
2016-04-14 17:45
The reason we are working on hyperledger fabric rather than ethereum is that we can put in our javascript smart contracts once someone writes a javascript module.
joequant
2016-04-14 17:45
There were some interesting legal reasons why we wrote the contracts in javascript.
joequant
2016-04-14 17:48
The legal reason we didn't use ethereum to write the smart contracts is that we have real money involved and we don't want the person on the other side claiming they didn't understand the contract. Since we are using this to fund tech companies, it's hard for them to argue that they didn't understand javascript.
buhrmi
2016-04-14 17:48
hahaha brilliant
joequant
2016-04-14 17:48
And you can parse the javascript into a web page for the judge to understand.
buhrmi
2016-04-14 17:49
"for legal reasons we use a language that everybody can understand" lol
joequant
2016-04-14 17:50
You are hosed if you write your contracts in a language that the judge can't understand.
buhrmi
2016-04-14 17:50
true
joequant
2016-04-14 17:50
I'm writing from Hong Kong. This actually poses a problem when people try to litigate an English contract in Mainland China.
buhrmi
2016-04-14 17:52
should look into the javascript module. i proposed javascript as main language to the hyperledger team before there was any code
buhrmi
2016-04-14 17:52
was thinking about similar reasons
joequant
2016-04-14 17:53
All someone has to do is to write a javascript chaincode container. Doesn't seem that difficult.
mdangear
2016-04-14 18:00
if you want contracts that judges can understand, consider using CommonAccord to add legal context to smart contracts https://github.com/commonaccord
joequant
2016-04-14 18:03
Trying to get a common contract framework that works with different national laws is a project that's too big for what I need right now.
joequant
2016-04-14 18:04
The approach we took was to base everything on HK law, which is more or less English law, and therefore similar to the law of commonwealth countries, including Kenya which we are doing business with.
buhrmi
2016-04-14 18:05
im in japan which is more or less bullshit law
joequant
2016-04-14 18:05
If you could get a framework that could produce both a valid HK contract and a valid Mainland Chinese contract, that would be amazing.
joequant
2016-04-14 18:05
Japan and China are both based on German law which puts a lot of emphasis on form.
joequant
2016-04-14 18:05
If you don't have the magic words, it's not valid.
buhrmi
2016-04-14 18:06
yeah and the banning of weed
buhrmi
2016-04-14 18:06
I'm German so I know :stuck_out_tongue:
mdangear
2016-04-14 18:06
the way I do with CommonAccord is that all contracts I create have generic clauses then “local” clause that apply based on geography and/or jurisdiction
mdangear
2016-04-14 18:06
works very well
buhrmi
2016-04-14 18:07
so the goal is to make local = global
joequant
2016-04-14 18:07
Have you checked with a lawyer to see that you end up with a valid local contract. The problem is that Mainland Chinese law and HK law are so different that it's not clear to me how you can templatize the differences.
mdangear
2016-04-14 18:07
nation and jurisdictions will not disappear tomorrow, better work for local and global both
joequant
2016-04-14 18:08
This might work for EU because you have common contract standards.
joequant
2016-04-14 18:09
The standard thing that gets people in trouble is that they take a contract translate it into Chinese and find that it's totally unenforceable in Mainland China because the logic of contracts is just different.
buhrmi
2016-04-14 18:09
yeah a lot also gets lost in translation, sometimes even on purpuse
joequant
2016-04-14 18:12
For example, most disclaimers of liability turn out to be unenforceable. NDA and non-competes have to be consistent with legal requirements or else they are unenforceable. If the judge sees one unenforceable clause, then the person can argue lack of good faith and get the whole contract nulled.
joequant
2016-04-14 18:13
For trade contracts, you can fix a lot of things by saying that the contract is taken under HK law.
buhrmi
2016-04-14 18:13
that's why I like code. code doesn't care about nation and jurisdiction
mdangear
2016-04-14 18:15

buhrmi

joequant
2016-04-14 18:16
actually my code does care about nation and jurisdiction.
joequant
2016-04-14 18:16
you put the legal parts in the comments.
joequant
2016-04-14 18:16
It's a backup system.
joequant
2016-04-14 18:17
Suppose the blockchain goes down. You can then enforce the contract through traditional ways.
hazardj
2016-04-14 18:17
You could do it this way - using the form created by @christophera http://www.commonaccord.org/index.php?action=source&file=GH/ParticipatoryOrgs/LLC-Delaware-Simple/Doc/Acme_Authentic_LLC.md

christophera
2016-04-14 18:19
The original on github is markdown
joequant
2016-04-14 18:20
The other interesting contract is the profit share contract. It creates a legal trust which means that the contract can legally have it's own bank account and own property.
buhrmi
2016-04-14 18:20
i want a blockchain written in javascript and the smart contract language also being javascript and any browser or node server can be a node in the network :open_mouth:
joequant
2016-04-14 18:21
The problem with an LLC or corporation is that you still have to register the company with the registry. You don't have to register a trust.
joequant
2016-04-14 18:21
Which means the blockchain can create a legal entity.
christophera
2016-04-14 18:21
There is also some new work on how to accept investment money without an exit, using a dividend like Revenue Backed Securities
buhrmi
2016-04-14 18:23

buhrmi
2016-04-14 18:23
create a legal entity in the blockchain
joequant
2016-04-14 18:23
Yes.
joequant
2016-04-14 18:23
You just create a trust.
buhrmi
2016-04-14 18:24

christophera

Gotta run, but ping me if you are serious about transitional LLC DAC
joequant
2016-04-14 18:24
The node in the blockchain creates a trust with a trust agreement. At that point the trust can do legal stuff like hold a bank account. The trust agreement names the trust administrator, but the adminstrator just does the paperwork.
joequant
2016-04-14 18:25
The big problem is that you may end up with tax problems from hell, but I'm in HK.
joequant
2016-04-14 18:27
One thing that we figured out is that you need to make the agreement multi-jurisdictional. The trouble with corporations is that if the jurisdiction of the corporation wants to block you, you are stuffed. It's a single point of failure.
joequant
2016-04-14 18:28
If you have a trust that owns assets in several jurisdictions with automatic fallover if it becomes invalid in one jurisdiction, then it's less fragile.
joequant
2016-04-14 18:29
You write the trust so that if it becomes invalid in HK, then you fall over to Bermuda, BVI, Caymans, or somewhere else.

question. I'm still trying to track down a breakage in hyperledger fabric. I'm getting errors about the peer package having a corrupt tar header.

My best guess is that there is a flag that is getting misset and the tar package is not being generated.

It's blocking other work, so any help in getting it to work would be appreciated.

@joequant Regarding Docker TAR issues, make sure that the directory tree you’re building from does not have any open files - that’s caused failures for me in the past.
joequant
2016-04-15 14:46
@buhrmi the trust creation is already done. http://joequant.github.io/bitquant/smart-contracts/contract_viewer.html?contract=models/profit-share will create a legal entity on the blockchain that can do legal stuff (i.e. open bank accounts, sue people, get sued)
joequant
2016-04-15 14:47
@buhrmi Entity registration isn't that hard. The HK company registry has an api for setting up companies and you just need to link with that. The hard part is the paperwork that is associated with the company. Otomous is working on that on top of the ethereum blockchain.
joequant
2016-04-15 14:48
The only real missing piece is the javascript module. Once you have that, then we can onboard the smart contracts. I estimate that the current contracts will work up to transactions of about USD 1 million.
joequant
2016-04-15 14:51
@baohua I just forked and added some scripts.
muralisr
2016-04-15 14:51
@bcbrock: @joequant : that’s one of the reasons I wanted to get the full logs from the peer… it should show up there. However, my instinct is that’s not not the issue as it seems to have progressed further. but yes, that’s something to make sure of
joequant
2016-04-15 14:52
I want to see if there is an issue once I move everything to baohua's docker scripts.
joequant
2016-04-15 14:52
It will be cleaner to see if there is a problem.
joequant
2016-04-15 14:53
If it turns out to be a weird interaction with virtualbox then it's not worth following up if it works with a straight docker dev environment.

joshhus
2016-04-15 15:53
has joined #general
joequant
2016-04-15 16:14
The cost of trying to break the contract. If you owe someone a billion dollars, they would be willing to spend tens of millions of dollars in lawyers trying to break the contract, and if you throw tens of millions of dollars of lawyers at the scripts I've written, I suspect that it's likely you will find some problem.
joequant
2016-04-15 16:15
If you have a contract that's worth USD 1 million, then it's likely that someone would only be willing to spend say USD 50k to break the contract, and I think that 50k worth of lawyering wouldn't find holes.
joequant
2016-04-15 16:16
USD 1 million is my estimate of how big the contract would be before someone hires enough lawyers to try to break the contract.
joequant
2016-04-15 16:18
One thing once you get into big numbers. If you have a USD billion contract, it is pretty likely that someone will try to sue you to break the contract. The question is how much you are likely to spend to defend against the suit.
joequant
2016-04-15 16:19
The more firm the contract the less money you will have to pay to defend the suit, but there is a tradeoff in that they more you will have to pay a lawyer up front.
joequant
2016-04-15 16:20
If the amount of the transaction is USD 1000, it doesn't make sense to pay a lawyer USD 5000 or even USD 100 to "harden" the contract.
joequant
2016-04-15 16:21
The problem with ethereum is that I can't imagine someone willing to put more than USD 1000 at risk.
joequant
2016-04-15 16:23
The thing about my smart contracts is that I think I'm the only person that has ever put real money on a smart contract. The deals that we were looking at were USD 10-30k deals.
buhrmi
2016-04-15 16:24
and the simpler the contracts the harder they are to break...
joequant
2016-04-15 16:26
That's sometimes true and sometimes not true.
joequant
2016-04-15 16:26
What you want is to use the same contract that's been used for the last 100 years.
joequant
2016-04-15 16:26
cut and paste.
joequant
2016-04-15 16:27
Or the same contract everyone else uses.
joequant
2016-04-15 16:27
Like the ISDA master agreement.
joequant
2016-04-15 16:28
Breakage is not a binary issue. What I care about is time and money. The likelihood that some lawyer will *try* to give me problems.
joequant
2016-04-15 16:30
I remember when JPMorgan bought Bear Stearns, they set aside USD 5 *billion* to deal with lawsuits and settlements.

joequant
2016-04-15 16:35
Actually this is one reason we used javascript. Enough people know javascript to reduce the likelihood of bugs, and there are some nice testing tools.
joequant
2016-04-15 16:38
If there is a bug in the contract and it says that IOU one billion dollars, then you can void the contract, because at that point it's "obvious" that there was a bug. The problem is if I think I owe USD 20k, but the code says I owe USD 50k.
buhrmi
2016-04-15 16:38
yeah but your javascript contracts live in what blockchain?
joequant
2016-04-15 16:38
They are going to live in hyperledger/fabric :simple_smile: :simple_smile:
buhrmi
2016-04-15 16:39
not openblockchain?
joequant
2016-04-15 16:39
openblockchain has become hyperledger/fabric. but OBC doesn't have a javascript module yet.
buhrmi
2016-04-15 16:39
ah
joequant
2016-04-15 16:39
One important part of the smart contracts we wrote is that it's blockchain agnostic.
joequant
2016-04-15 16:40
In fact you don't have to run them in a blockchain at all.
joequant
2016-04-15 16:40
But it's really useful if you do because then you can connect the contract to SWIFT.
joequant
2016-04-15 16:44
My plan is that once I get my smart contracts onto a blockchain system that does automatic transfer of payments, then I write another contract that bundles several thousand of them into a trust that turns into a blockchain hedge fund.
joequant
2016-04-15 16:48
You can then offer tokens for that blockchain hedge fund. In order to buy a share, you need to present a token that says "I have been authorized by the SEC to buy hedge funds" and a token that says "I am not a US tax resident". Once you present those tokens, then everything else can be automated.

We had 30+ members attend the Identity kickoff discussion. Consensus is that our scope is sufficiently different that our work doesn't quite fit into existing working groups (though we will interface and contribute to them), we are asking to be an official Hyperledger WG. We currently plan to use a dedicated public slack channel for our discussions # and have a call approximately every other week. A doodle poll for the next meeting will be sent shortly. Finally, we look forward to meeting in person at the next Hyperledger meeting, and maybe at the ID 2020 Design Workshop in May.

@joequant: two comments on your smart contract to create a Trust agreement: 1. this is great 2. this seems to be going reverse. While coders can automate transactions, they are not lawyers and should not have to be. So rather than having coders come up with legal to add to their code, it should be coder providing chaincode that can be added to legal documents. I would love to see the chaincode called from a contract built with CommonAccord. There are tons of agreements already for seed or series A funding, and many others actually, and you could imagine enforcing the transactions (including for example the right of first refusal of one of the investor wants out) using chaincode. You can check this example here http://www.commonaccord.org/index.php?action=doc&file=bq/fr/bnpp/a5we/0.md it includes series A document, plus refers to the initial funding. All investors are defined as objects, and you can have all the other docs related to the formation of the corp. Also note this example of how chaincode could be called from a doc is here: http://www.commonaccord.org/index.php?action=doc&file=./S/Sandbox/Blockchain/TransactionTypeQw3rty02.md

Hey! Bob Summerwill from the Ethereum project here. I am attending OSCON in Austin this May, and I would like to extend an invitation to anybody who will be in Austin on 18th May to come along to a one-off Meetup which I have been arranging to bring together blockchain and DLT developers of all stripes to talk about all the cool stuff we are building! I have already been in contact with Nitin Gaur, of the IBM Blockchain lab there in Austin, and his colleagues. Factom are hosting, and we should have people from at least Bitcoin, Ethereum and Hyperledger. I'm trying to get an invite out to the R3 Consortium too. Please do spread this invite to any friends or colleagues who you think may be the interested!

ASIDE#1 - I found the terminology introduced in this article ... "Open Execution" ... a lens which could be very useful in helping people to understand what this new category of technology is about: https://www.linkedin.com/pulse/how-open-execution-replace-source-jason-carver

ASIDE#2 - The attendee list for OSCON is online and there are huge number of people there from Capital One. Does anybody know if they are working on any blockchain tech? Are they part of the Hyperledger Consortium, for example? I don't think they are in R3. But they are certainly very, very open-source friendly and agile.

What happens when PUT_STATE failed somehow. For example,
``` // To company
err = stub.PutState(accountPrefix+tr.ToCompany, toCompanyBytesToWrite)
// From company
err = stub.PutState(accountPrefix+tr.FromCompany, fromCompanyBytesToWrite)
if err != nil {
return nil, errors.New("Error writing the fromCompany back")
}```
Assume PutState( ToCompany, <json>) succeeded, and the amount was increased or dereased. However, also assume PutState( FromCompany, <json>) failed, and world state does not changed. My understanding is that, this transaction in chaincode failed, as a result new block is not created. But I wonder what will happen in world state.

Oh, by the way. I just joined to this slack. PLease let me know if "general" is not right location for this kind of discussion.
muralisr
2016-04-18 01:37
@ibmamnt: we should take it to fabric or technical-discuss I suppose
muralisr
2016-04-18 01:39
but the state should be unchanged as well
ibmamnt
2016-04-18 01:40
@muralisr: Thanks. I'll check using my experimental code. And if I find something, I'll post to technical-discussion channel or fabric.

Hi, not sure if this is the right channel for the following question, but can someone please advise if the setup.sh for hyperledger can be used directly onto Ubuntu Machines (we didnt want to use the Vagrant environment). Would really appreciate some help/guidance around this
srbamb
2016-04-18 05:25
we could setup OBC on the same machines but have to now migrate to Hyperledger since the former has been declared deprecated
jasmeet

@srbamb: Even i have the same question
baohua
2016-04-18 05:48
@srbamb: @jasmeet You can have a look at https://github.com/yeasy/docker-hyperledger. It provides non-vagrant environment. You can enjoy with direct docker, or just follow the Dockerfile to setup a baremetal env.

Hi, anyone know how to construct a chaincode deploy REST API call using http? I follow the instructions at https://github.com/hyperledger/fabric/blob/master/docs/API/CoreAPI.md#chaincode, and put the whole dict as the POST payload, however, error happens with "400 Client Error: Bad Request ("{"jsonrpc":"2.0","error":{"code":-32700,"message":"Parse error","data":"Error unmarshalling chaincode request payload: invalid character 'p' looking for beginning of value"},"id":null}")"

I'd like to recommend Thomas Greco as a board member. I've worked with him on a project similar to this in the past. We built an alternative currency system for the city, and were unable to scale beyond a single locale because we lacked something like HyperLedger to perform the tasks of a locale-independent clearing house.

I am a newbie to blockchain as well as hyperledger.
joseph
2016-04-19 14:48
I understand that if I use chaincode to write an application. It means that I write a smart contract.
joseph
2016-04-19 14:48
Is it true?
sheehan
2016-04-19 14:58
Yes, chaincodes are similar to smart contracts. If you need more info, see the # channel

All, is there an overview of all slack channels, who is the "chair" of them and what topic is beeing addressed in it? We currently have 18 channels and not all of them are clear to me what topic is beeing addressed. Also some of them seem to be non active. If we do not have this, could we please address this?
ry
2016-04-19 21:28
I don’t think there is any restriction on people creating channels; I suspect many of them are ad-hoc
ry
2016-04-19 21:28
If you click on the “channels” dropdown, it will at least show you who created the channel.
arnaud
2016-04-19 23:31
@andreas.fletcher: as @ry said, anyone can create a channel so it's pretty organic. Practically, you can always start from # and if your question belongs to a specific channel you will be told about it.

One thing that might be useful is to just dump INSTALL.md and CONTRIBUTING.md onto the wiki so we can play with it, and then periodically sync it with github.

I am not sure if someone know this performance benchmark from bitshares, 100,000PTS is also our commitment to the customer in financial field. So, I think some good points from bitshares can be considered in the hyperledger, such as memory cache, has separate cryptographic component to handle hash and signatures, divide the state-dependent/independent validation and etc.

My host is running on a VM and it is not able to boot the guest VM..As per theh fabric docs it says it will fail to boot the guest with an error VT_X not available. but in my case it does not print any error..Is the nesting of virtualization not supported?

Anybody around who knows how to run hl/fabric with security enabled?
chetsky
2016-04-21 22:40
I think I've been able to configure it, but this "peer login" thing is completely puzzling
chetsky
2016-04-21 22:40
not sure how that's supposed to work
tuand
2016-04-21 22:41
login from rest api or from cli ?
chetsky
2016-04-21 22:45
tuan, hi
chetsky
2016-04-21 22:45
I've started the CA, and 4 peers
chetsky
2016-04-21 22:45
the next step says
chetsky
2016-04-21 22:45
cd $GOPATH/src/github.com/hyperledger/fabric/peer
./peer login <username>
tuand
2016-04-21 22:45
did you start membersrvc ?
chetsky
2016-04-21 22:45
yes
chetsky
2016-04-21 22:45
also vp0-vp3
chetsky
2016-04-21 22:46
they came up and seem to have established comms
tuand
2016-04-21 22:46
core_security_enabled=true ?
chetsky
2016-04-21 22:46
yes
chetsky
2016-04-21 22:46
I actually got the enrollid/secret wrong the first N times, so I'm pretty sure it's actually logging into the CA
chetsky
2016-04-21 22:47
this peer login -- it's a CLI command that hits vp0? or what?
tuand
2016-04-21 22:47
yes, goes against vp0
chetsky
2016-04-21 22:47
so you can see where I'm headed: https://github.com/chetmurthy/fabric/tree/chet-hacks-20160419
chetsky
2016-04-21 22:48
if you look at README.CHET, you'll see that I'm buiding scripts to set up and run N (=64?) peers+chaincodes, then manage 'em etc.
chetsky
2016-04-21 22:48
want to do this for security
chetsky
2016-04-21 22:48
I'll try that login cmd again vp0
chetsky
2016-04-21 22:48
thank you
chetsky

gotit. thanks!
tuand
2016-04-21 22:50
i think that's the message when it thinks you've already logged on using that id
chetsky
2016-04-21 22:51
unfortunately, I have not logged-on with the ide
chetsky
2016-04-21 22:51
b/c I used "chet" pass "chet"
chetsky
2016-04-21 22:51
which certainly wasn't used before
chetsky
2016-04-21 22:52
I guess I need to use one of the passwords in membersrvc.yaml?
tuand
2016-04-21 22:53
yes, use the test_userX ids
chetsky
2016-04-21 22:53
can you tell me what their passwords are?
tuand
2016-04-21 22:54
i think what you do is : log on to vp0/1/2/3 using a different test_userX then for every op to a vp, add -u test_userX to the call
tuand
2016-04-21 22:55
the pw is the string following the "1"
chetsky
2016-04-21 22:55
so "test_user01" ??
tuand
2016-04-21 22:55
everybody calls it "secret" rather than pw
tuand
2016-04-21 22:57
so login with test_user0 on vp0, test_user1 on vp1 and so on
chetsky
2016-04-21 22:58
oh my god
chetsky
2016-04-21 22:58
tmp/vp0/PEER login -p MS9qrN8hFjlE test_user0
chetsky
2016-04-21 22:58
that worked
chetsky
2016-04-21 22:59
this is isn't paper-thin!
tuand
2016-04-21 22:59
you sound surprised :simple_smile:
chetsky
2016-04-21 22:59

While running this step -Start up the peer node with no connections to a leader or validator as follows.
cd /opt/gopath/src/github.com/openblockchain/obc-peer

I’m interested in all blockchain business issues. I assume people can iterate and build the technology, but I want to understand markets, business cases, needs, customer journey, etc. I’m much more interested in asking questions and doing experiments than to have technical answers focused on blockchain. What problems are we trying to solve, and how will we connect to our customers? These kinds of questions. As William Mougayar says: "Building new applications on the blockchain is about 80% business process changes, and 20% technology implementation."

I am also interested in the business side of blockchain implementation. A small group of us, who have extensive experience in insurance industry data standards, are looking at using this technology. I personally am an experienced solution architect. While I am interested in the nuts and bolts of how bc works, our group is also interested in building the business case especially around product definition.

hello, i've a question regarding the spec
kat
2016-04-26 04:28
https://github.com/hyperledger/fabric/blob/master/docs/protocol-spec.md says
Chaincode services provides a secured and lightweight way to sandbox the chaincode execution on the validating nodes. The environment is a “locked down” and secured container along with a set of signed base images containing secure OS and chaincode language, runtime and SDK layers for Go, Java, and Node.js. Other languages can be enabled if required.
kat
2016-04-26 04:28
signed why and by whom?
j3ffyang
2016-04-26 04:55
My team is developing a solution of leveraging HyperLedger, for a TV station, to
1. Identify ownership of a digital asset, such as microMovie and music, when "Post"
2. Record "Ownership", "Share" and "Payment of ownership when transferred" into distributed ledger
3. Define exchange/ tx of shared ownership into SmartContract, then link to finalized payment (connect to real money thru payment gateway)

# is the group
kat
2016-04-26 06:36
@j3ffyang: to be more specific, the image is part of consensus rules, but it is indicated it is non-uniform across the network
kat
2016-04-26 06:36
specifically that arbitrary programming languages can be added
j3ffyang
2016-04-26 06:40
@kat sort of understanding your points :stuck_out_tongue: it's related to sets of standard of
+ data format within ledger -> so far I saw the discussion about "Linked Data" https://www.w3.org/TR/json-ld/
+ consensus protocol which should be controlled by client API and the way of deployment into container (code deployment in Docker)
kat
2016-04-26 06:42
hmm. linked data? huh, you mean that contract would indicate hash of image it is compatible with or something along the lines?
kat
2016-04-26 06:48
well, for now i'm going to assume everybody is forced to run the same image or evil things happen
kat
2016-04-26 06:50
second thing i'm worried about is hardcoded consensus resolution algorithms (PoW, Paxos etc)
kat
2016-04-26 06:50
how is hyperledger supposed to support arbitrary algorithms when these are hardcoded, is there a rationale these aren't run in a vm too?
j3ffyang
2016-04-26 07:32
Will show you our metadata (in linked data structure) in distributed ledger in a specific digital asset.
Well, thinking of a standard of chaincode coding that is open- sourced, like verified container image, maintained by community.

I have got this example https://github.com/IBM-Blockchain/marbles run locally.

I saw that it downloaded chaincode from https://github.com/ibm-blockchain/marbles-chaincode.
joseph
2016-04-26 15:00
the chaincode was stored on harddisk at /marbles/node_modules/ibm-blockchain-js/temp/unzip.

Could you please explain me how the chaincode was loaded and run locally inside the example?

mcrafols
2016-04-26 15:05

joseph
2016-04-26 15:08
@mcrafols: Could you explain it further?
mcrafols
2016-04-26 15:09
nodejs is just a fancy way to use the REST API
mcrafols
2016-04-26 15:10
it calls the REST api to deploy the chaincode
mcrafols
2016-04-26 15:10
chaincode is executed in the VP after reaching consensus
joseph
2016-04-26 15:15
you mean it send golang code of chaincode to the VP and VP executes it? For example, If want to query chaincode, the source code below is sent to the VP?
joseph
2016-04-26 15:15
====================================================================================
// Query - Our entry point for Queries
// ====================================================================================
func (t *SimpleChaincode) Query(stub *shim.ChaincodeStub, function string, args []string) ([]byte, error) {

// Handle different functions

@ghaskins: I’m newbie to the fabric. I am very curious why golang was inside nodejs code. :smile:
ghaskins
2016-04-26 15:29
ah, the answer is that it isnt
mcrafols
2016-04-26 15:29
everything is magic until you know how it works
ghaskins
2016-04-26 15:29
it might appear that way, but the golang chaincode is sent to the validator which then compiles it as straight golang code into a binary
ghaskins
2016-04-26 15:30
@mcrafols: heh, indeed
ghaskins
2016-04-26 15:30
anything that is “in” nodejs is just acting as a front end to that process
ghaskins
2016-04-26 15:31
the validator itself is written in golang, though that has little to do with why/how the chaincode is processed
ghaskins
2016-04-26 15:32
i guess you could look at it like [golang::chaincode]->[nodejs::client]->(network)->[golang::validator]->[golang::container]
ghaskins
2016-04-26 15:33
so the first and last parts are golang/chaincode related, the stuff that happens in the middle is more or less a transport
ghaskins
2016-04-26 15:33
i.e. the client in nodejs and the validator in golang matter little here
ghaskins
2016-04-26 15:34
but maybe its better to leave it a mystery and not shatter @joseph’s impression its all voodoo magic :wink:
joseph
2016-04-26 15:35

Newbie Question on Peer / Node discovery: I was able to get the Peer node on my Mac following the instructions. Instead of setting up a Dev Network using Docker Images on the same machine I used another Mac to run another node/peer.

: as a reminder, the TSC is currently a function of the premier membership - with each Premier sponsor naming an individual to represent them on the TSC for the first six months. After the initial six month period, the TSC becomes an elected body. The electors are those who have contributed a commit or to the development of the Requirements, Architecture, Identity and Whitepaper WGs. To be nominated to run for one of the TSC seats, you need to also have at least one commit or have contributed as above.

: all, until we get Jenkins set up, for the fabric builds, which are using TravisCI, please add [ci skip] to PRs for changes to markdown files only (e.g. README.md etc)
bcbrock
2016-04-27 22:58
@cbf: Does your comment suggest that the CI environment is giving a lot of false fails? How can I clear my good name if I think my “failing” PR is actually working? Or are the committers ignoring the failures? Thanks.
cbf
2016-04-27 23:02
it seems that there are either lots of false failures or there is some behavior in pbft consensus that needs to be cleaned up, but yes there have been numerous CI fails of simple markdown tweaks, which makes no sense
cbf
2016-04-27 23:03
also, too… skipping the Travis build for doc changes will speed things up when we get to a point that we’re maxing on concurrent builds
arnaud
2016-04-27 23:08
@cbf you put [ci skip] in the PR description? On its own, at the end for instance?
arnaud
2016-04-27 23:13
Thanks
arnaud
2016-04-27 23:15
Now I'm wondering why there isn't a configuration to do that automatically if the commit only includes certain types of files
ramesh
2016-04-28 01:06
Commits with [ci skip] anywhere in commit message will ignore by Travis CI ex: git commit -m "skipping [ci skip]"
ramesh
2016-04-28 01:09
for PR's, Travis CI checks for the latest commit and if the commit message is tagged with [ci skip], Travis CI ignores the build process.
ramesh
2016-04-28 01:11
this will be use full, when you want to open a pull request early for review but you are not necessarely ready to run the tests right away.
tuand

I followed this guide
joseph
2016-04-29 03:56
joseph
2016-04-29 03:57
I deploy the chaincode as
joseph
2016-04-29 03:57
CORE_PEER_ADDRESS=172.17.0.2:30303 ./peer chaincode deploy -p http://github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02 -c '{"Function":"init", "Args": ["a","100", "b", "200"]}'
joseph
2016-04-29 03:57
It’s ok.
joseph
2016-04-29 03:59
Then I modified the chaincode and re-deployed.
joseph
2016-04-29 03:59
But I didn’t see this change on validating peers.
joseph
2016-04-29 04:00
Who could give me some ideas about this problem?
muralisr
2016-04-29 04:29
@joseph: just did
muralisr
2016-04-29 04:30
basically if you are running multiple peers in docker, did you rebuild the image after modifiying code ?
joseph
2016-04-29 04:31
No. I didn’t rebuild the images of VPS.
muralisr
2016-04-29 04:32
if you are deployyng modified code from the filesystem (in vagrant) you’d have to do that
muralisr
2016-04-29 04:33
the “-p <chaincode path>” has to exist in the go path on the VP you are pointing to
joseph
2016-04-29 04:34
I got it.
joseph
2016-04-29 04:35
Does it work if I copy the modified chaincode to the VP docker instead of rebuilding?
muralisr
2016-04-29 04:35
there are a variety of ways to do this … including using docker volumes.
muralisr
2016-04-29 04:36
but I’d just try —peer-chaincodedev mode followed by rebuilding peer
muralisr
2016-04-29 04:37
and yes, you could copy the modified chaincode to the VP the request is addressed to
joseph
2016-04-29 04:38
@muralisr: thanks.
joseph
2016-04-29 04:39
@muralisr: could you make your answer on OS link.
joseph
2016-04-29 04:39
It’s useful for someone else.
muralisr
2016-04-29 04:39
I thught I did...
muralisr
2016-04-29 04:39
thought
muralisr
2016-04-29 04:39
don;t you see it ?
joseph
2016-04-29 04:40
yup. I saw it.
muralisr
2016-04-29 04:52
ok
joseph
2016-04-29 05:27
Does it automically upload chaincode to VPs?
muralisr
2016-04-29 05:28
@joseph: I haven’t recently (I should…). I’d think it loads your chaincode for you undercovers
muralisr
2016-04-29 05:29
btw, did rebuilding peer work for you
joseph
2016-04-29 05:29

2016-05-02 06:25
@andrew.keys: @cbf Great presentation on the EVM, the interoperability of private and public chains for simple integration and development is key. I am very excited for this in a none biased way. The EVM solves the key issues when interacting across different business (even if in a private way) which is what blockchains are about, interacting in a trustless way. For example the use of gas will be needed in both public and private. You could even expand this to a chargeable model for clouds when private hosting.
juanblanco
2016-05-02 06:27
I am also rather happy to see the collaboration flourishing in this early stages, as it will be a risk in the future of having yet again different types of chains, which will be very difficult to interop.

It's not far fetched to observe http + html + javascript + browser is a great blockchain infrastructure with the browser implementing the "fabric" execution platform... :bulb:
Anyone can script a web application "blockchain" ( using javascript, provide ui using html, specialize the application using REST to utilize the cloud, pledge some kind of security assurances using certs) and count on trusted browsers to securely execute the application.
Methinks it checks off a good number of fundamental requirements of a "Hyperledger" with the "consensus" mechanism being the overall experience if it is generally contended by the user that it fulfills whatever need he had of the application, i.e. Ordering pizza :stopwatch:
kendagor
2016-05-03 11:59
I believe this may qualify as a very loose edge use case...
kendagor
2016-05-03 12:04
It does bring forth elements that may be interesting later on down the road for Hyperledger, for example conceptualizing a richer than command-line UI blockchain on the fabric..
simon
2016-05-03 12:08
what are trusted browsers?
kendagor
2016-05-03 12:10
The small set of well-known browsers users have by human consensus agreed are generally fine to use: firefox, chrome, IE/Edge (without prejudice :) )
simon
2016-05-03 12:24
trusted in what way?
simon
2016-05-03 12:24
that's all the browsers that are out there
jamie.steiner
2016-05-03 12:31
the trust store that ships with browsers is basically the PKI trust anchor for the internet. whether that's a good idea or not is debatable, but it does seem to be the state of affairs.
simon
2016-05-03 12:34
i think that's not what kendagor meant with trusted browser
kendagor
2016-05-03 12:35
And to discover such an application the www uri is the unique signature to the application. It begs to ask, are we doing a 22nd century reinvention/perfection of the wheel?
simon
2016-05-03 12:37
kendagor: i don't understand what you are talking about
simon
2016-05-03 12:37
are you saying that the web is a blockchain?
sth
2016-05-03 12:39
Is "trust" necessary, or is "trustlessness" - the certainty of algorithmic outcomes - the essence of interactions with blockchain applications including web browsing?
simon
2016-05-03 12:40
web browsing is full of trust
sth
2016-05-03 12:41
unnecessarily so, imo.
simon
2016-05-03 12:41
how would it work with less trust?
simon
2016-05-03 12:42
it's all about trusting identities, or delegates of identities
kendagor
2016-05-03 12:46
Simon, correct, it's legitimate to make that observation that the browserland web is a blockchain and with an open mind evaluate what we're doing in Hyperledger if we're treading the same path but perhaps with some key deficiencies we're trying to fix and the question would be what those are.
sth
2016-05-03 12:46
one attraction of, for example, smart contracts is that I don't have to trust the other party to perform, it is pre-determined by the algorithm that I can fully understand - in principle :wink:
simon
2016-05-03 12:47
kendagor: but the web isn't a blockchain - it has none of the properties
sth
2016-05-03 12:47
ipfs, if I understand correctly, aims to correct that.
jamie.steiner
2016-05-03 12:48
ipfs is also not a blockchain - but it is awesome :wink:
sth
2016-05-03 12:48
sorry to deviate from hyperledger, my bad.
jamie.steiner
2016-05-03 12:50
I actually think ipfs is a key enabling technology for blockchains, and the Merkle DAG might have many great uses within blockchains.
simon
2016-05-03 12:52
how is ipfs related to blockchains?
jamie.steiner
2016-05-03 12:56
ipfs describes data purely based on content and it's hash value, via the Merkle DAG. It is, in a sense, immutable, like blockchain. Both have censorship resistance as a goal. Both are equalizing forces that empower individuals. I see them as ideological allies, beyond the plain "you can store a blockchain on IPFS" or "you can enter a MerkleDAG root into a blockchain"
simon
2016-05-03 12:58
what's the difference between merkle DAG and merkle tree?
jamie.steiner
2016-05-03 13:02
simon
2016-05-03 13:02
so the same
jamie.steiner
2016-05-03 13:03
they are different data structures, but share some properties

2016-05-03 20:40
are there currently any “public nodes” running the hyperledger fabric?
tleyden
2016-05-03 20:40
or if I wanted to play with fabric I’d have to convince some other folks to participate in a private blockchain?
vipinb
2016-05-03 20:47
You can run your own with multiple peers
tleyden
2016-05-03 21:02
I see. So to play with it, I can spin up multiple peers that I control, and then to do something useful with it, I’d have to form a network of peers who wanted to participate.
tleyden
2016-05-03 21:03
Is there an issue if one entity controls > 50% of the nodes like in bitcoin? Can the blockchain be forked/manipulated in that case?
tleyden
2016-05-03 21:05
I guess what I’m really asking is whether there are docs that describe the security model of hyperledger/fabric .. and how that differs from something like bitcoin or ripple
cbf

@tleyden: no, it is a permissioned network that we’ve deployed on bluemix - consensus is pbft not pow.

I have questions related to chaincode. When we design a system based on hyperledger, we will implement a chaincode for a specific scenario. When we use such a system, it will deploy multiple chaincode instances for different business transaction instances. It means the chaincode instances will increase infinitely. Is there any method to address this problem? Another question is about the upgrade of the chaincode, what is the suggested practice to perform chaincode upgrade caused by bug fix, policy upgrade, system upgrade, etc.
muralisr
2016-05-04 03:05
@weizhao: there have been discussions on instances and some activity in life-cycle (for example please see https://github.com/hyperledger/fabric/issues/1127). Currently new chaincode creation depends only on the “deploy” verb. That will likely change in future to accomodate upgrade and creation of instance
gengjh
2016-05-04 03:07
answer your second question: yes, as @muralisr mentioned that is chaincode lifecycle management which is still WIP.
muralisr
2016-05-04 03:07
Some active discussion on instances can be found for example in https://github.com/hyperledger/fabric/issues/373
muralisr
2016-05-04 03:08
there’s work to be done in all these areas and there are many approaches to this. For example, instances can be thought of as instantiations of a chaincode or as one chaincode managing instances as state and so on.

Hi, does anyone have issues with IBM's blockchains samples? I've downloaded a few of their apps such as the marbles sample and the commercial paper app. The web front end and blockchain service run, but don't seem to connect. The web UI has a popup saying "Waiting on the node server to open up so we can talk to the blockchain. This app is likely still starting up. Check the server logs if this message does not go away in 1 minute.", but this never goes away... i've tried removing the app and deploying to bluemix again, but no luck...

Bluemix. I've just been using the deploy to Bluemix button from GitHub

Yes I know, just doesn't seem to work any more. I had it working around two weeks ago using my Bluemix account, just seemed to stop working

that's probably because they are updating it to work with hyperledger

I have a question about PBFT. so it's possible that in a private network with a small number of peers, a subset of nodes greater than "m" of PBFT can collude in rigging the chaincode output to their advantage and to the disadvantage of the honest nodes, thus defeating the consensus. Essentially such a network can only work based on the assumption that m (number of rogue nodes tolerated by PBFT) is large enough to make it impossible for that many parties to collude. would we then come to the logical conclusion that PBFT would not be suitable for a network with less than 10 nodes (assuming it’s relatively easy for 2 parties to agree on an evil plot but difficult to get 3 or more to do that), with each node owned by a truly independent entity?

garisingh
2016-05-05 19:41
@jzhang: PBFT is proven to work for 3f+1 peers where f = number of faulty (system or malicious) nodes. So if you want to tolerate 2 faulty nodes, then you need (3*2) + 1 = 7 nodes. But in general, the tone of the question is correct - when designing a PBFT network you need to take into account the number of faulty nodes you expect / can tolerate. If you had 4 peers, you can tolerate 1 faulty peer so if 2 colluded, the network would halt but the integrity of the data would be intact
jzhang
2016-05-05 19:54
@garisingh: when you say “data would be intact” how is it guaranteed that output from chaincode execution can’t be altered by a group of malicious nodes > f?
garisingh
2016-05-05 20:02
@jzhang: in the example I gave, there were 4 nodes and only 2 colluded so that would not be 2f+1 votes - meaning consensus would not be reached, things would halt but state would not be updated either. But if there were 3 out 4 nodes colluding, then of course you have 2f+1 and the 4th node would have to accept the changes agreed on by the others.
garisingh
2016-05-05 20:03
but if 3 of 4 were colluding, then its probably not collusion according to the proof
jzhang
2016-05-05 20:17
"if 3 of 4 were colluding” - that’s exactly what i’m getting at, it’s totally conceivable that as a business I’d be really nervous about participating in a small network like that because it’s not hard to imagine the 3 other parties could be colluding for consensus. so I’d only be comfortable to join a network > 4 nodes if consensus is based on PBFT (assuming I decided that it’s impossible for more than 3 parties to collude)

Good day - requesting some help from the community here.
There’s a speaking opportunity for a Blockchain webinar series we are running - to draw more attention to the Hyperledger project and highlight its potential impact on the Blockchain ecosystem. We’re looking for 1-2 speakers!
I’m Eric from Lynk. Our mission is to enable people to share knowledge and expertise, which is why we’re running this webinar series.
The session on Hyperledger will be one part of a series we’re doing. Topics are:
1. Finding practical applications/use-cases for corporations
2. Bitcoin security - what’s in development and what should we expect
3. Trends in ethereum smart contracts and decentralized apps
4. Hyperledger and the readiness of enterprise-grade Blockchain development
5. Future of Sidechains and associated challenges
6. Assessing Impact of Blockchain technology on our society
7. How this new technology can be used to make financial markets more transparent
The webinars are tentatively scheduled for early June.
We’re inviting nominations from you guys on who you would like to see as a speaker on the topic of Hyperledger. Please help me by nominating a few people who would be good speakers for the Hyperledger session.
Thanks very much!

@jzhang, @garisingh: if you have 2 byzantine nodes in a 4-node network, it doesn't imply that consensus doesn't make progress. consensus can make progress (depending on what the byzantine nodes do), but your correctness is no longer guaranteed. In other words, the colluding byzantine nodes could craft an alternate blockchain development (and even history, to some degree) and accuse the other two (actually correct) replicas of colluding. No way to tell the difference.

Critical dev ops item came up in Identity WG yesterday and in the face2face general session today - "Fiduciary Code" - review and promotion of the code base releases probably ought to be locked down and signed via electronic signatures and entitlements and perhaps its own blockchain - this is crucial basis for eating own dog food and tamperproofing - audit/compliance/legal review-friendly items needs to start with the code base, runtime crypto and logging is not sufficient

Related to "Fiduciary Code" are "Fiduciary Events". Runtime events like a smart contract that evals to false needs to be recorded in the blockchain for non-repudiation purposes. Likewise, voting a validator node in or out has business / regulatory implications, so should also be recorded on the block.

Approximately. I think at DTCC we had about 50 or 75 people, but it followed on Confluence, which boosted attendance

@ry Around 50. We could go up to 75.

Hi all, I am posting a message here with some questions regarding membership services. I am a French developer who recently left his job to create a startup around B2B blockchain applications. I have been following the blockchain's ecosystem for some time now and I strongly believe the Hyperledger's specifications makes it perfectly suited for B2B applications. I started working around some business cases on the Hyperledger protocol. I want to simulate a full bockchain network, ie several companies working on an unique blockchain with different access rules (as described in the 4th protocol-spec paragraphe). However as mentionned in the 4,7th paragraphe some restrinctions in the current release don't allow it. Is there roadmap for the implementation of the fully operational membership service ? Thanks for your answers.

I have a very basic question for the group... Bitcoin incentivizes the mining network by coining new BTC in each block. What sort of incentive system or virtual currency/asset will hyperledger offer to participating miners?
cbf
2016-05-10 23:55
we aren’t using POW. Right now we have a few alternate consensus algorithms - pbft (couple of flavors) and POET which is Intel’s Proof of Elapsed Time (see Swatooth lake repos)

Hello all ~ Thank you for the add.
I am new to all of this. I have read countless Blockchain documents and at this point it is getting worse, I am understanding less :disappointed: ...
So to remedy this I need to understand a practical implementation of Blockchain, aka, get code and actually do something with it. Being that I am so new at this, where is absolute step 1 for a person like me? Where do I start?
(Also, if this is not the correct form, I am sorry as I know we are all very busy etc...)

@vivsoft: For fabric, you can start with the Getting started guide (https://github.com/hyperledger/fabric/blob/master/docs/README.md), building the peer guide (https://github.com/hyperledger/fabric/blob/master/docs/dev-setup/install.md) and finally, the building and running chaincode guide (https://github.com/hyperledger/fabric/blob/master/docs/API/SandboxSetup.md). Working through those should give you a pretty good idea of what fabric is about.

for the hardware requirements, i have not found any statement regarding this. really depends on your business logic and how many transactions will be handled. At least we need 8GB memory I think

2016-05-12 15:52
you first fork the repo - that will essentially create a copy under your user id

then you clone that copy to your local machine to work on
arnaud
2016-05-12 15:54

I am trying to connect and send data to the first Validating Peer (VP) with the IP address and port number CORE_VM_ENDPOINT=http://172.17.0.1:2375. How do I connect and send data to the VP from devices located on other networks on the internet? I am currently running through the page (Setting Up a Network For Development: https://github.com/hyperledger/fabric/blob/master/docs/dev-setup/devnet-setup.md). My understanding is that the IP address 172.17.0.1 is assigned to an host on a CLASS B Network. And a class B network is reserved for use by private networks that are not connected to the internet. I am willing to open a port to my computer from my router (connected to the internet) and do port forwarding. Please advise. Thanks.
vpaprots
2016-05-12 18:55
@maro have a look at -p option under docker (i.e. -p 5000:5000 will map/forward ports from docker to the host machine..) at which point you need to open your host machine firewall up..
vpaprots
2016-05-12 18:58
if you are running Linux on your host, the command will look something very similar to `iptables -I INPUT -p tcp --dport 5000 -j ACCEPT` (haven't tested, just from .bash history)

dhkim717

yes, to do "Go build",
dhkim717
2016-05-13 15:06
in previous line, From within the VM, you can build, run, and test your environment
arnaud
2016-05-13 15:06
yes, from the VM
dhkim717
2016-05-13 15:07
but, in VM, I can not access the files
arnaud
2016-05-13 15:07
once you've done the first step of building your VM using vagrant up, you should do everything else within it
arnaud
2016-05-13 15:07
you should be able to
arnaud
2016-05-13 15:07
there are in $GOTPATH/src
arnaud
2016-05-13 15:08
your disk is mounted into the VM
arnaud
2016-05-13 15:08
you do vagrant ssh, right?

which should be /opt/gopath/src/...
dhkim717
2016-05-13 15:10
oh.....working!!!
arnaud
2016-05-13 15:10
that fabric directory and everything underneath is the same fabric directory that you started from
arnaud
2016-05-13 15:11
it's better not to use git within the VM in my experience
arnaud
2016-05-13 15:11
do all your git stuff and editing from your own machine
arnaud
2016-05-13 15:12
but for builds and tests you do in the VM (vagrant ssh)
dhkim717
2016-05-13 15:12
ok! I will keep in mind!
arnaud
2016-05-13 15:15
so, typically once you're set up, you do your editing using whatever editor you like on your machine, then build and run/test from within the VM
arnaud
2016-05-13 15:15
when you want to update your code, commit, or push code, you do it on your machine
arnaud
2016-05-13 15:16
"your machine" meaning not within the VM
arnaud
2016-05-13 15:16
once you get used to the dual mode it becomes pretty easy
arnaud
2016-05-13 15:17
you just have to have enough windows open and labelled correcly to know on which machine you are
arnaud
2016-05-13 15:17
I often use uname though, to confirm :slightly_smiling_face:

@joseph: would need details please….can you provide logs from peer, chaincode and the list of commands issued ?
joseph
2016-05-14 14:17
logs from peer and chaincode there were not error.

@joseph: I’m just a bit familiar with this code but I believe java-gRPC usage in here https://github.com/hyperledger/fabric-api might serve as a guide. In particular I’d take a peek at https://github.com/hyperledger/fabric-api/tree/master/api/src/main/proto

Hi, Can someone provide an example of GetRows? I’ve given it a crack but it doesn’t seem to be working..
david.acton
2016-05-15 12:39
Also, is there a way to do debugging, i.e. step through debugging?
ghaskins
2016-05-15 13:20
@david.acton: If you follow the sandbox setup (https://github.com/hyperledger/fabric/blob/master/docs/API/SandboxSetup.md#vagrant-terminal-1-validating-peer), you ultimately are launching the chaincode yourself….once you do that you can launch it under a debugger such as https://github.com/derekparker/delve
ghaskins
2016-05-15 13:21
for instance, if you add “dlv exec” in front of the chaincode launch, you get step debugging
david.acton
2016-05-15 14:05
@ghaskins Thanks!! I’ve got things setup and I have a lot of code written…. it’s just the debugging that was missing. I’ll give this a go! thank you
sheehan
2016-05-15 16:28
@david.acton: there's a test chaincode which exercises the getRows function at https://github.com/hyperledger/fabric/blob/master/bddtests/chaincode/go/table/table.go
For Fabric specific questions, the #fabric channel is the best place to ask

Could someone share how to deploy chaincode from a private git repo to BlueMix? The url deploy like this https://bluemix.net/deploy?repository=https://github.com/ibm-blockchain/marbles.git seems to fail on private repos (looks like BMX just clones master) and the chaincode REST deploySpec looks like it does the same. I think I'm looking for a cloud foundry based deploy from my cloned repo.
cbf
2016-05-17 11:33
the current requirements are for the chaincode to be in a public git repo (not necessarily GitHub)… extending to support private repos would require a secure means of exchanging credentials needed to clone a private repo
simon
2016-05-17 11:36
cbf: i've been arguing that we should ship the source during (REST) deploy, and not just the url
muralisr
2016-05-17 11:52
@cbf @simon there was talk of SDK supporting source directly
nickmelis
2016-05-17 11:54
@muralisr: interested in that too
nickmelis
2016-05-17 11:54
out of curiosity, why is a source file on a public repo the only option atm?
muralisr
2016-05-17 11:59
@nickmelis: please see https://github.com/hyperledger/fabric/issues/873 (in particular, the last comment summarizes)
muralisr
2016-05-17 12:01
as @cbf pointed out, the real issue is "extending to support private repos would require a secure means of exchanging credentials needed to clone a private repo” … and that has to be done within the security context of the user and peer. Rest are mechanics
nickmelis
2016-05-17 12:02
are you saying send the contract code via the REST api is not an option?
muralisr
2016-05-17 12:03
not at all. That is certainly an option. I was refering to private vs public
nickmelis
2016-05-17 12:03
ah ok sorry :slightly_smiling_face:
nickmelis
2016-05-17 12:03
yeah I guess getting code from a private repo may be a bit of a pain
cbf
2016-05-17 12:05
PRs welcome;-)

@nickmelis: the only supported types in upstream are native golang and car-based golang, but plenty more are in the works

the platform types are extensible though: so the hooks are in place, theres just nothing implemented other than golang

Should you be interested in participating in either of these, please complete your availability at your earliest convenience. Note -- these will be 1-2 day events. We are honing in on general availability on a week-by-week basis and will narrow down to specific days from there.
June (virtual Hackathon): http://doodle.com/poll/tzmnqwe279sfzwa2

Is there a way to generate a random string in a chaincode that will be uniform accross all peers ?
ibmamnt
2016-05-19 05:53
I was able to see several ways in golang to produce ramdom string. Try to search for yourself. uniform means unique ? I also found uuid generator shared sample in play.golang ( https://play.golang.org/p/4FkNSiUDMg ) <== do not use, this has serious bug.
clyde_dcruz
2016-05-19 05:57
okay . but would this function give the same value in all the peers ?
ibmamnt
2016-05-19 06:00
Probably, it depends on how you implement random string function.
ibmamnt
2016-05-19 06:00
rand() normally gives identical value if the argument is the same.
ibmamnt
2016-05-19 06:01
if rand is given the argument, like time and data. It can be different.
clyde_dcruz
2016-05-19 06:02
right. but is it possible to get the time at which the Transaction was submitted ? rather than using the current time on peer (will be different on each peer i guess)
ibmamnt
2016-05-19 06:05
I guess you can put current time (or universal time) of client who issued transaction, and include that time as transaction argement.
ibmamnt
2016-05-19 06:06
Say, '"invoke", "["a", "b", "10", "2016051903110000"]'
clyde_dcruz
2016-05-19 06:07
passing it as argument is the sure shot way
clyde_dcruz
2016-05-19 06:07
what about ts, err2 := stub.GetTxTimestamp()
ibmamnt
2016-05-19 06:10
ibmamnt
2016-05-19 06:11
```// GetTxTimestamp returns transaction created timestamp, which is currently
// taken from the peer receiving the transaction. Note that this timestamp
// may not be the same with the other peers' time.```
ibmamnt
2016-05-19 06:12
I think this can be used in stead of putting it into transaction.

2016-05-19 06:12

@nickmelis: hyperledger-fabric itself is more low level: an application platform for apps that want to mutate state via consensus….you can (and people are) build asset-management/cryptocurrency applications on top of that platform, however. In fact, the “example02” that ships in the tree is a primitive form of that. There are probably others too
ghaskins
2016-05-19 11:35
You can see a token payment happening here in a port of example02 I wrote recently: https://github.com/ghaskins/chaintool/tree/chaintool-0.7/examples/example02#step-6---make-a-payment

@clyde_dcruz: I had this time discussion for IoT contracts a few months ago, and submitted issue #875 to ask to have the shim make the transaction time available to the contract as we need reliable (or at least consistent) timestamps on all incoming events. This was fixed recently, and so is the only way you can store a timestamp and have it pass consensus. A real advantage of this technique is that your internal state changes, if timestamped, will perfectly align with the transaction time on the blockchain itself. That, in my opinion, is an excellent audit feature (my contracts retain the event history in world state.)

the transaction time, however, is selected by the submitting peer and can be invalid if the peer is byzantine or has a broken clock
simon

not invalid, but wrong
kletkeman
2016-05-19 14:29
@simon, yes, I agree ... but until there is a time service available that can inject a reliable transaction time, I cannot see any other solution that comes close to addressing the need and the consensus issue ...
simon
2016-05-19 14:29
yes, i know
kletkeman
2016-05-19 14:30
I'm thinking more of captive fabrics than public fabrics, which might mitigate the risks somewhat
simon
2016-05-19 14:33
well if you can deal with wrong time, fine
simon
2016-05-19 14:33
but then you might as well not use it, or only as best-effort, untrusted
simon
2016-05-19 14:34
if you require trusted time, then you cannot use it
simon
2016-05-19 14:34
if you say "i trust the machines setting the right time", then you might as well not use a byzantine fault tolerant blockchain at all, and use your trusted machine as a centralized server

I have been trying to configure the dev environment for HL using Virtual Box 5.0.20 & Vagrant 1.7.4 on Windows 7. While doing that my OS crashes with driver_irql_not_less_or_equal message. Any help on what can be causing this?
karan
2016-05-21 10:15
This is being caused by ndis.sys maybe due to the additional drivers that get installed with Virtual Box.
karan
2016-05-21 10:16
Any suggestions to help me complete the dev set up will be useful

@muralisr: , @joseph Thanks for your response :slightly_smiling_face: . Is there a correct way to schedule a change in chaincode state OR to periodically do a state change based on some conditions ?
muralisr
2016-05-21 16:54
@clyde_dcruz: without “time/timer services” in the fabric, any scheduling have to be take care of at the application level. But the requirement is known ( https://github.com/hyperledger/fabric/issues/1321 )
muralisr
2016-05-21 16:56
the above is necessary (but not sufficient) for timer services

muralisr

is your peer running and reachable ? Perhaps a CORE_PEER_ADDRESS=<address:30303> is needed ?
joseph

you mean 'CORE_PEER_ADDRESS=0.0.0.0:30303 ./peer network login jim' ?

replacing the 0.0.0.0 with an appropriate IP

looked like the peer was not running on inaddr_any for some reason :slightly_smiling_face:

Let say. I am setting up the network https://github.com/hyperledger/fabric/blob/master/docs/dev-setup/devnet-setup.md
joseph
2016-05-21 17:28
First, I started the CA server, ./membersrvc

Yup

I’d ignore the sendProducerBlockEvent error
muralisr
2016-05-22 02:33
that’s not the root cause
muralisr
2016-05-22 02:34
I’d do a go build in that dir to make sure it builds
muralisr
2016-05-22 02:34
get that to build (and rm the exe after doing that)
joseph

I did
joseph
2016-05-22 02:36
errors again
muralisr
2016-05-22 02:38
does it work without security enabled ? I’d suspect not...
joseph
2016-05-22 02:44
No. I'm sorry. wait a minute
joseph
2016-05-22 02:47
No. it doesn't also without security enabled.
muralisr
2016-05-22 02:50
right
muralisr
2016-05-22 02:54
I’m guessing you are doing some imports in chaincode that go pulls in vagrant
muralisr
2016-05-22 02:54
one approach
muralisr
2016-05-22 02:54
instead of deploying chaincode
muralisr
2016-05-22 02:54
run /bin/bash
muralisr
2016-05-22 02:54
and do go install
muralisr
2016-05-22 02:54
that should give you the exact failure
joseph
2016-05-22 02:55
what do you mean 'run /bin/bash'?
muralisr
2016-05-22 02:56
can you copy paste peer command
joseph
2016-05-22 03:00
docker run --rm -it -e CORE_VM_ENDPOINT=http://172.17.0.1:2375 -e CORE_PEER_ID=vp1 -e CORE_PEER_ADDRESSAUTODETECT=true -e CORE_PEER_DISCOVERY_ROOTNODE=172.17.0.2:30303 hyperledger-peer peer node start

sorry.. how do you mean ?
muralisr
2016-05-22 03:08
perhaps you want to rebuild the image ?
joseph
2016-05-22 03:09
I mean that the docker using my old chaincode I created some day ago.
joseph
2016-05-22 03:10
we have to rebuild the image before every deploying?
muralisr
2016-05-22 03:13
in this case, yes
muralisr
2016-05-22 03:13
there are other ways
muralisr
2016-05-22 03:13
put your code in a public github repo for example
muralisr
2016-05-22 03:14
but for now building peer with the new chaincode will do the trick...
muralisr
2016-05-22 03:14
I need to go now.. will check later if you need help

I want to a certificate by calling stub.GetCallerMetadata().
joseph

2016-05-22 05:23
Am I missing sth like configurations or *.yaml?
joseph
2016-05-22 05:24
Please me some ideas around calling stub.GetCallerMetatdata()?
clyde_dcruz
2016-05-22 05:29
i guess the metadata needs to be passed in the transaction like :
clyde_dcruz
2016-05-22 05:29
spec := &pb.ChaincodeSpec{
Type: 1,
ChaincodeID: &pb.ChaincodeID{Path: "http://github.com/hyperledger/fabric/examples/chaincode/go/asset_management"},
//ChaincodeID: &pb.ChaincodeID{Name: chaincodeName},
CtorMsg: &pb.ChaincodeInput{Function: "init", Args: []string{}},
Metadata: adminCert.GetCertificate(),
ConfidentialityLevel: confidentialityLevel,
}
clyde_dcruz
2016-05-22 05:39
If you have security turned on , then you can get the caller's certificate by using: cert,err := stub.getCallerCertificate()

muralisr
2016-05-23 11:58
@hgabor : system chaincodes are deployed by the peer. It is just a note to indicated that the deploy path is equivalent to what a user would typically do to initialize. It does NOT mean user has to deploy again.
hgabor
2016-05-23 12:03
@muralisr: so I only need to add my own lines to importsysccs.go, write my own chaincode (using e.g. utxo), start a peer and that's all? :slightly_smiling_face:

@codascud On AWS it's much better to create an AMI (Amazon Machine Instance). There used to be some (unsupported!) hacks for getting some versions on some AWS instances, but it's not recommended. In general, nested virtualization is not supported in these environments...

@codascud: NP. I believe (though haven't actually tried it myself with HL/Fabric) you can try to replicate the configuration scripts that install the dependencies on vagrant up. Most of it are mainly Golang dependencies and Docker containers...
jonathanlevi
2016-05-23 18:05
Though at this point, you might as well try to get some non-virtual instances that do not prevent you from running vagrant/VBox, or so... which should work "out of the box".
codascud
2016-05-23 18:11
@jonathanlevi: got it... I am able to run on my laptop without any issues.. its the AWS that was a problem.. Will try to install dependancies manually sometime later… Thanks...

it looks like you can set up a dev environment (and deploy the chaincode without relying on a public github) by following the steps at https://github.com/hyperledger/fabric/blob/master/docs/API/SandboxSetup.md

@nickmelis: I assume you are talking about the fabric roadmap and the answer is not quite yet, although the maintainers just started a weekly meeting: https://github.com/hyperledger/hyperledger/wiki/PublicMeetingCalendar - Hyperledger Project - Fabric Technical Planning

I think the first meeting was yesterday and unfortunately I could not attend so not sure. Perhaps @binhn @ghaskins @tamas can answer
tamas
2016-05-24 09:59
@binhn enumerated current activity on fabric. You are right, a roadmap toward features formulated in working groups and an update on progress online was the ideal outcome. We will have to get there. I am afraid not for this first meeting.

hey, just thought i’d share: today i successfully deployed a fabric cluster and ran the asset management demo live at the GlueCon keynote using the Apache Brooklyn blueprint (https://github.com/cloudsoft/brooklyn-hyperledger/tree/add-membersrvc)! people definitely seemed interested in the tech afterwards :slightly_smiling_face:

Then I invoked it stub.getState("admin")

muralisr
2016-05-26 03:36
@joseph it means that chaincode ID of the deployment transaction does not match the chaincode ID associated with the current transaction
muralisr
2016-05-26 03:37
do you know the commands you used for the deploy transaction and the trans that causes this error ?
muralisr
2016-05-26 03:38
for some reason the chaincode ids dont match

few mins
joseph
2016-05-26 03:54
yup
muralisr
2016-05-26 03:57
the path param is left out of the deploy TX
muralisr
2016-05-26 03:58
but I see it in your JSO
muralisr
2016-05-26 03:58
JSON
muralisr
2016-05-26 03:58
are you using REST ?
joseph
2016-05-26 04:01
yes. I am using REST.
joseph
2016-05-26 04:04
you mean the path param was not in the deploy TX?
I used the deploy statement: "{\"jsonrpc\":\"2.0\",\"method\":\"deploy\",\"params\":{\"type\":1,\"chaincodeID\":{\"name\":\"stock\",\"path\":\"http://github.com/chaincode-app-go/core\"},\"ctorMsg\":{\"function\":\"init\",\"args\":[\"hello_world\"]},\"secureContext\":\"jim\"},\"id\":1}"
muralisr
2016-05-26 04:05
right. I see it there
muralisr
2016-05-26 04:05
but I don’t see it in the deploy tx that was retrieved from the ledger
muralisr
2016-05-26 04:06
so not quite sure what’s happening
muralisr
2016-05-26 04:06
can you try the example from CLI ?
muralisr
2016-05-26 04:06
even before that...
muralisr
2016-05-26 04:06
can you try the exact same thing but in non dev mode ?
muralisr
2016-05-26 04:07
I think you’ll make progress
muralisr
2016-05-26 04:08
oh wait
muralisr
2016-05-26 04:08
try removing \"path\":\"http://github.com/chaincode-app-go/core\” from the invoke and query
joseph
2016-05-26 04:12
wow. It works now. :slightly_smiling_face:
muralisr
2016-05-26 04:12
:slightly_smiling_face:
joseph
2016-05-26 04:12
thank you so much.
joseph
2016-05-26 04:12
but when we should use or not use the path?
muralisr
2016-05-26 04:12
well
muralisr
2016-05-26 04:13
we need to debug this a bit..
muralisr
2016-05-26 04:13
in general, invoke and query should not have -p
muralisr
2016-05-26 04:14
deploy should
muralisr
2016-05-26 04:16
but we should not have the user figure that out…. part of the problem is the user mode which requires “-n” option on deploy
muralisr
2016-05-26 04:16
need to think thru this and probably debug (I think I came across this before) so we do the right thing automatically
muralisr
2016-05-26 04:17
but will have to do it tomorrow…er, later today :slightly_smiling_face:
joseph
2016-05-26 04:19
I got it.
joseph
2016-05-26 04:20
thank you again. :slightly_smiling_face:

2016-05-26 04:20

Hello! I am new to hyperledger and want to figure out how its parts fit together. There is description of API in protocol specification. Where is it implemented - REST service from `hyperledger/fabric` repo or `hyperledger/fabric-api`? How are these two related?
joseph
2016-05-26 04:59
hyperledger/fabric
lexsys
2016-05-26 05:01
ok. And what is `hyperledger/fabric-api`?
joseph
2016-05-26 05:02
it may became a client/SDK of the fabric in the future,
lexsys
2016-05-26 05:04
oh, I see! Thank you

Another question is about membership service. Does it issue and store ECerts and TCerts, or only verifies them based on root Cert and we need separate Cert management infrastructure?
nickmelis
2016-05-26 08:33
general question: I read something about events in HyperLedger, but there’s no API related to events
nickmelis
2016-05-26 08:33
is it something in the roadmap? Or it’s already out there?
mcrafols
2016-05-26 08:38
nickmelis
2016-05-26 08:44
@mcrafols: I guess it doesn’t use the REST api, am I right?
mcrafols
2016-05-26 08:46
I have no clue how it works I just remembered this post:
nickmelis
2016-05-26 08:49

Can I ask a simple question? Is there a way to setup a Hyperledger fabric node on Amazon EC2 without building?
ghaskins
2016-05-26 15:27
@tribbloid: I don’t think there is today out of the can, but I see no reason you couldnt get it to work if you are willing to put the legwork in
ghaskins
2016-05-26 15:28
if you started with a trusty/14.04 AMI and ran the following scripts:
ghaskins
2016-05-26 15:28
ghaskins
2016-05-26 15:29
(in that order)
ghaskins
2016-05-26 15:29
it will get you fairly close
tribbloid
2016-05-26 15:29
thank you!
tribbloid
2016-05-26 15:29
the first script setup the build environment
tribbloid
2016-05-26 15:29
the second compile
ghaskins
2016-05-26 15:29
let us know how it goes, i suspect this will be interesting to many folks going forward
tribbloid
2016-05-26 15:30
it will be great to make a public ami out of it
ghaskins
2016-05-26 15:30
well, the primary objective of both of those scripts is to get the dependencies installed
ghaskins
2016-05-26 15:30
but the second script does indeed compile the peer too
ghaskins
2016-05-26 15:30
but you can do that manually over and over after the deps are installed
tribbloid
2016-05-26 15:31
will try and get back to you in seconds
ghaskins
2016-05-26 15:31
those scripts are more or less what we execute to configure the vagrant environment, but its 99% ubuntu specific not vagrant specific
ghaskins
2016-05-26 15:31
heh, you’ve obviously never run those scripts before
ghaskins
2016-05-26 15:31
more like 30 minutes :wink:
ghaskins
2016-05-26 15:31
(the first one has to compile a bunch of stuff that isnt available in trusty)
ghaskins
2016-05-26 15:32
ultimately I would love to see a pipeline which automates not just vagrant/docker, but also AMI, GCE, Azure, etc
ghaskins
2016-05-26 15:32
but we arent there yet
tribbloid
2016-05-26 15:35
soory I mean will try in seconds and get back
ghaskins
2016-05-26 15:36
heh, i was just teasing, and also mentally preparing you that its going to take a while
ghaskins
2016-05-26 15:36
the first script in particular
ghaskins
2016-05-26 15:38
(for clarity, the reason there are two scripts is we break it up such that the first one results in an image we can reuse (e.g. a dockerhub or vagrant-box), and the second represents logic that we do dynamically on top
ghaskins
2016-05-26 15:39
so, the first script represents the closest to what might be a sensible AMI to publish
ghaskins
2016-05-26 15:40
if you end up really needing AMI support, a way to get this officially in the pipeline would be to add an AMI provisioner to https://github.com/hyperledger/fabric/blob/master/images/base/packer.json#L13
ghaskins
2016-05-26 15:41
you can follow the vagrant provisioner as a model
ghaskins
2016-05-26 15:42
patches welcome
tribbloid
2016-05-26 15:42
first script up and running

ghaskins
2016-05-26 16:19
sorry about that, I should have thought of it being I just hit it myself
tribbloid
2016-05-26 16:19
hope the script doesn't use other sourcecode, as your branch is several commits behind from upstream master
ghaskins
2016-05-26 16:19
it shouldnt, but it will probably merge cleanly if you want to pull master on top
ghaskins
2016-05-26 16:20
actually, you raise a good point though
ghaskins
2016-05-26 16:20
that branch is pointing to a new unreleased/untested base image
ghaskins
2016-05-26 16:20
you are better off cherry picking that one commit
ghaskins
2016-05-26 16:20
im still qualifying the 0.0.10 release right now
ghaskins
2016-05-26 16:21
otherwise, you run the risk of hitting something in 0.0.10 that might have nothing to do with your goals
tribbloid
2016-05-26 16:24
one extra suggestion:
tribbloid
2016-05-26 16:24
could you add this?
tribbloid
2016-05-26 16:24
sudo rm -R /opt/go
tribbloid
2016-05-26 16:24
I mean rm -R /opt/go
ghaskins
2016-05-26 16:26
in the base image script?
tribbloid
2016-05-26 16:27
yeah, so the mv command won't complain that the dir already exist if the script was interrupted before
ghaskins
2016-05-26 16:27
i see…I _could_ but it was really designed to provision clean systems
ghaskins
2016-05-26 16:28
so not sure it should be cluttered up that way
ghaskins
2016-05-26 16:28
i know what you are getting at though
ghaskins
2016-05-26 16:28
let me think about it

Hi All, I am new here and trying lear the Fabric project. Looking for instruction to setup 2/3 node private/test network. Can any one point me to right documents?
ghaskins
2016-05-26 19:08
@tribbloid: you probably dont need to have the user be “vagrant” per se, thats just an artifact of the targeted use of that script originally
ghaskins
2016-05-26 19:09
I will say this though, whatever privilege was being conferred in that setup is probably something you want to replicate for whatever UID you get logged in as under EC2
tribbloid
2016-05-26 19:09
so which way is better? adding user or changing the script?
ghaskins
2016-05-26 19:14
whatever you prefer…if it were me, I wouldn’t want to confuse the EC2 environment with vagrant and would avoid flavoring it as such
ghaskins
2016-05-26 19:14
but I dont think its a big deal either way
sheehan
2016-05-26 19:29
@tribbloid: I haven’t tried it yet, but it seems the cloudsoft team have done some EC2 deployments via Apache Brooklyn https://github.com/cloudsoft/brooklyn-hyperledger/tree/add-membersrvc
tribbloid
2016-05-26 19:32
thanks a lot, the instruction says:
tribbloid
2016-05-26 19:32
If deploying to AWS You should use an up-to-date CentOS AMI
tribbloid
2016-05-26 19:32
which is far from the default Ubuntu-based vagrant image
tribbloid
2016-05-26 19:33
its hard to maintain the synchronisation between both environnment
tribbloid
2016-05-26 19:34
I would rather not taking the extra eisk
tribbloid
2016-05-26 19:34

I've added a new user and execute again, this time I got the following error information:
tribbloid
2016-05-26 19:54
./setup.sh: line 82: /hyperledger/scripts/provision/host.sh: No such file or directory
tribbloid
2016-05-26 19:54
this is the devenv/setup.sh
ghaskins
2016-05-26 20:00
i am not sure what your setup is, but the “/hyperledger” mount point is something vagrant creates which maps to the fabric tree
ghaskins
2016-05-26 20:01
so, in your AMI, you would either want to edit that path appropriately, or emulate the setup and have fabric.git available in the /hyperledger path as well
ghaskins
2016-05-26 20:01
either should work equally well.
tribbloid
2016-05-26 20:03
I see, sounds like a symbolic link can solve all the problem, let me try it and post any consequence
tribbloid
2016-05-26 20:03
hopefully we can edit the script to make it adaptive
ghaskins
2016-05-26 20:08
yeah, ive been slowly moving things out of ./devenv/setup.sh and into ./scripts/provision, with exactly that motivation
tribbloid
2016-05-26 20:08
building now after running this line:
tribbloid
2016-05-26 20:08
ln -s ~/git/fabric /hyperledger
ghaskins
2016-05-26 20:08
the things that remain in ./devenv would probably remain vagrant specific by design, but if we can capture all/most of the meat under scripts/provision then we can achieve the same effect
tribbloid
2016-05-26 20:09
why vagrant specific? so far all vagrant script are
tribbloid
2016-05-26 20:09
written for virtualbox provider
ghaskins
2016-05-26 20:10
well, to date we have three supported targets: vagrant, docker, and travis
tribbloid
2016-05-26 20:10
there are many more environment than this
ghaskins
2016-05-26 20:10
of those, ./images/base/scripts/common and ./scripts/provision are generic
tribbloid
2016-05-26 20:11
speaking of which, do you think this project:
tribbloid
2016-05-26 20:11
has more change to be accepted as canonical?
tribbloid
2016-05-26 20:11
since its written inn a language that is less environment demanding
ghaskins
2016-05-26 20:12
everything else, (e.g. [./devenv, ./images/base/scripts/vagrant] (vagrant), .travis.yml (travis), and [./images/base/scripts/docker, ./scripts/provision/docker] (docker) are specific to their target
ghaskins
2016-05-26 20:12
im trying to get the specific stuff as light as possible
ghaskins
2016-05-26 20:13
but I suspect there will always be some target specific logic _somewhere_ no matter how close we get, its generally irreducible
ghaskins
2016-05-26 20:14
regarding the link, i think this is what that became: https://github.com/hyperledger/fabric-api
ghaskins
2016-05-26 20:15
bottom line, we know/understand the platform support is a little too opinionated…we are working on that
ghaskins
2016-05-26 20:15
in the early days, we only supported x86/vagrant/virtualbox
ghaskins
2016-05-26 20:16
have since added docker, travis, and s390x, with more on the way
tribbloid
2016-05-26 20:23
encounter another error:
tribbloid
2016-05-26 20:23
./setup.sh: line 94: cd: /opt/gopath/src/github.com/hyperledger/fabric: No such file or directory
tribbloid
2016-05-26 20:24
another symbolic link?
tribbloid
2016-05-26 20:25
the gopath folder is empty at this point
ghaskins
2016-05-26 20:31
so, two things:
trinoy
2016-05-26 20:31
has joined #general
ghaskins
2016-05-26 20:31
1) you need to have the fabric available as $GOPATH/src/github.com/hyperledger/fabric
ghaskins
2016-05-26 20:31
2) you need to have $GOPATH/$GOROOT set appropriately
ghaskins
2016-05-26 20:32
i am assuming your have (2), and just need to set up (1)
tribbloid
2016-05-26 20:44
Sorry I though (1) is already handled by the first script?
tribbloid
2016-05-26 20:44
I've seen lots of script outputs using $GOPATH
ghaskins
2016-05-26 20:44
no, neither of those scripts will load the actual project code
tribbloid
2016-05-26 20:45
so how does it work in vagrant before?
ghaskins
2016-05-26 20:45
vagrant load its as part of devenv/Vagrantfile
ghaskins
2016-05-26 20:45
travis loads it in a similar way
ghaskins
2016-05-26 20:45
those tools all start with a git-checkout before the VM config starts
ghaskins
2016-05-26 20:46
your AMI is different, its more like a real box
ghaskins
2016-05-26 20:46
heres where vagrant is doing it
tribbloid
2016-05-26 20:46
I see, their images are already built with Go environment
tribbloid
2016-05-26 20:46
but AWS is not
ghaskins
2016-05-26 20:47
travis is, yes
ghaskins
2016-05-26 20:47
for vagrant, we do it in that script under ./images/base/scripts/common/setup.sh
tribbloid
2016-05-26 20:49
I've just run that before!
ghaskins
2016-05-26 20:49
thats what I thought
ghaskins
2016-05-26 20:49
so, you should have go installed
ghaskins
2016-05-26 20:49
note that you might have to logout/in to get the envvars though
ghaskins
2016-05-26 20:50
the script updates /etc/profile.d, but that would only be processed at login
tribbloid
2016-05-26 20:50
I have $GOPATH
ghaskins
2016-05-26 20:50
ok, cool
tribbloid
2016-05-26 20:50
ubuntu@ip-172-31-11-24:/opt/gopath$ echo $GOPATH
/opt/gopath
tribbloid
2016-05-26 20:50
but its empty
ghaskins
2016-05-26 20:50
so now just make sure you have $GOPATH/src/github.com/hyperledger/fabric
tribbloid
2016-05-26 20:51
looks like something should be in ./images/base/scripts/common/setup.sh but was delegated to Vagrantfile
tribbloid
2016-05-26 20:51
the sync
ghaskins
2016-05-26 20:51
what part?
ghaskins
2016-05-26 20:52
but I assume you already have the tree local since you are accessing scripts, etc
tribbloid
2016-05-26 20:52
yes, its like a circular dependency
tribbloid
2016-05-26 20:53
to run the script I need git clone it to a local folder
tribbloid
2016-05-26 20:53
the script will create $GOPATH
tribbloid
2016-05-26 20:53
while assuming that I have cloned into the $GOPATH
ghaskins
2016-05-26 20:54
i understand, but theres not much you can really do about it
ghaskins
2016-05-26 20:54
most software doesnt try to help you install deps
ghaskins
2016-05-26 20:54
these scripts are, but as a result of using them, yes I suppose its a little circular
ghaskins
2016-05-26 20:54
you could chose not to use the scripts and do it by hand, but then its probably more work for you
ghaskins
2016-05-26 20:55
but bottom line, it was all designed to work with vagrant via “vagrant up”….anything else is emerging
tribbloid
2016-05-26 20:55
deps management is a very important part in both installation (e.g. apt-get) and compilation (e.g. maven, npm)
ghaskins
2016-05-26 20:55
i agree
ghaskins
2016-05-26 20:56
but even if you use something like maven, you still have to pull the pom first
ghaskins
2016-05-26 20:57
right now, the equivelent of “mvn build” is “vagrant up"
ghaskins
2016-05-26 20:57
it will build all the deps for you (short of installing vagrant/virtualbox, just like maven wont install maven)
ghaskins
2016-05-26 20:57
we need to do more than just vagrant, but its not quite there yet
tribbloid
2016-05-26 21:00
yeah, this is limited to local dev environment, the Vagrantfile confine everyone to launch a virtualbox with 4G memory, unable to scale up or down according to production demand.
ghaskins
2016-05-26 21:00
understood
ghaskins
2016-05-26 21:00
the project is young, thats just the state it is in right now
ghaskins
2016-05-26 21:00
patches welcome :slightly_smiling_face:
tribbloid
2016-05-26 21:02
it would be my pleasure
tribbloid
2016-05-26 21:03
but that's why I was asking if other candidates are likely to be accepted as well.
ghaskins
2016-05-26 21:04
you mean something in addition to hyperledger/fabric?
ghaskins
2016-05-26 21:04
have to step out, bbiab
tribbloid
2016-05-26 21:04
e.g. Sawtooth lake, and hlp-candidate written in Java/Scala
tribbloid
2016-05-26 21:05
not to fabric, but to hyperledger as a superproject
tribbloid
2016-05-26 21:05
eventually companies will reach a consensus platform-wise to minimize their effort
tribbloid
2016-05-26 21:07
and fabric is one of the 4 candiates
tribbloid
2016-05-26 21:08
ok, build finished with no error

@tribbloid: hyperledger-incubator/hlp-candidate has been superceded and is now hyperledger/fabric-api and is actually part of the same incubating project as hyperledger/fabric
cbf
2016-05-27 00:39
there are two incubating projects presently, fabric and sawtooth lake. My hope would be that at some point these are synthesized into a single platform

Github changed the policy a while back to be opt-in public. The problem though is that private members are not visible (duh) to the general public.

one thing to note, queries are read-only, so if you are trying to update rows in a query handler, that will not work

Hi, is non-deterministic execution supported by Sieve consensus protocol implemented in fabric?
ghaskins
2016-05-31 02:15
sieve is implemented, and sieve _prevents_ non-deterministic execution…is that what you meant?
zuowang
2016-05-31 03:00
@ghaskins: I mean is probabilistic algorithms supported in chaincode?
zuowang
2016-05-31 03:02
@ghaskins: I saw in the sieve paper "Protocol Sieve, in the modular approach, has been developed for executing potentially non-deterministic "smart contracts” as applications for a blockchain built with BFT replication" Thank you for your reply!
ghaskins
2016-05-31 03:11
Im not sure what you mean by “probabilistic algorithms”, but I think you misinterpreted the the intent of sieve
ghaskins
2016-05-31 03:11
its not meant to _permit_ non deterministic smart-contracts, but rather to detect/mitigate them
ghaskins
2016-05-31 03:15
non determinism is the enemy of a consensus network, sieve aims to ensure non-determinism doesn’t slip in to the block chain.

@ghaskins: thank you for your response! But I'm trying to insert a row using Invoke(), not Query(). My concern is, Do I have to send any metadata or certificate sort of arguments in REST call. Can a normal user insert a row into the table? Or has it to be an administrator?
ghaskins
2016-05-31 10:24
Each chaincode has its own private KV store, and each chaincode decides it's access policy. You could leave it wide open, but I suspect most applications will do some sort of ABAC
ghaskins
2016-05-31 10:37
@zuowang: short answer is "no". The long answer is right now the container is not very locked down so you could in fact access one. It's just a bad idea. Some consensus algorithms (like seive) will detect that you did this and reject your transactions. Others will fail to detect it but you will have a corrupted network. Either way, it's a negative outcome.

I just would like to know if it could be possible to delete a block on Hyperledger ? For example if the block involves 2 participants, theses two particpants could agree to remove a block ("invalid chaincode" , "wrong transaction" for example).
bfuentes
2016-05-31 13:31
I am not sure at all that all blocks are linked all together with hashes like for Bitcoin. So if it is true, it could be done, right ?
ghaskins
2016-05-31 13:31
in short, I don’t think that should ever be allowed…you would want a compensating transaction instead
bfuentes
2016-05-31 13:33
in case of a transaction yes, why not. In case of a wrong chaincode deployed ?
bfuentes
2016-05-31 13:33
it should be purged
bfuentes
2016-05-31 13:34
no compensation for that
ghaskins
2016-05-31 13:34
the entire point is to build an immutable history, that mistake is part of your history
bfuentes
2016-05-31 13:35
well on a transaction point of view yes
bfuentes
2016-05-31 13:35
on chaincode deployed , not really
ghaskins
2016-05-31 13:35
yes, mistakes are undesirable/unfortunate, but not nearly as unfortunate as a blockchain that cannot prevent integrity violations
ghaskins
2016-05-31 13:35
chaincode deployments are just another type of transaction
bfuentes
2016-05-31 13:37
so old useless chaincodes still remains on the blockchain
bfuentes
2016-05-31 13:37
we cannot update their code
bfuentes
2016-05-31 13:38
we will have to add a new block and to point to this one ?

2016-05-31 13:44
to be clear, you cannot (by design) “update” the record of historical state…you can always propose new state to be added to the chain…new state can include new code
ghaskins
2016-05-31 13:45
blockchains are like snapshots of immutable data, you can only propose new snapshots not delete snapshots
ghaskins
2016-05-31 13:46
so I wouldnt classify it was “we cannot update their code"
ghaskins
2016-05-31 13:46
you can update a chaincode (or delete it, or add other chaincodes, etc) as a new state
ghaskins
2016-05-31 13:47
@bfuentes: does that make sense?
bfuentes
2016-05-31 13:50

@mart0nix: Ok, I understand Are the attributes you described, such as serial number and manufacturer, stored as part of the value when calling PutState?
mart0nix
2016-06-01 07:24
I get JSON documents with key-values that describe a transaction (change of custody, old owner, new owner, business step, etc...)
mart0nix
2016-06-01 07:25
I have experience with Ethereum where I would use the transaction event logs to log those values so that I can scan the blockchain for them later
mart0nix
2016-06-01 07:25
I'm not sure how PutState could be utilized in my example - is that using native storage or it somehow works with logs as well ?
mart0nix
2016-06-01 07:26
@lfeagan: I can chat you privately a full JSON example of the data I'm trying to store
lfeagan
2016-06-01 07:33
@mart0nix: I don’t think the answer I am going to give right now is going to be as satisfying as you might like, but you have "run into" the right person, as I am the "database guy" that has a proposal to address short-comings of the present implementation. I do want to help.
lfeagan
2016-06-01 07:34
@mart0nix: The PutState method is used when writing chaincode to save state to the ledger. Ultimately, this state gets saved into a RocksDB key-value store with a name of the form <chaincode-id>_<key>.
lfeagan
2016-06-01 07:35
@mart0nix: While this state can be queried, if you wanted to have an expression to pull out something from a JSON-value, that would not perform well today, as there are no secondary indexes (database terminology).
mart0nix
2016-06-01 07:37
@lfeagan: well I'm getting JSON documents from from my API but I don't want to store the data in JSON format on the blockchain
mart0nix
2016-06-01 07:38
I can store them as key-values but I need to encapsulate them somehow so that I know those are part of one single transaction
mart0nix
2016-06-01 07:38
does that make sense ?
lfeagan
2016-06-01 07:41
Yes, it does. I wish somehow the work I just started were magically done because I think it would address your issue nicely. We just started the wiki page for the proposed ledger storage architecture and capabilities: https://github.com/hyperledger/fabric/wiki/Next-Ledger-Architecture-Proposal
lfeagan
2016-06-01 07:44
I have a *very* rough prototype and design sketches. I will be adding details and having discussions to address issues such as the ones you bring up in the coming days/weeks.
mart0nix
2016-06-01 07:47
@lfeagan: I guess it would be awesome if one can store data on the chain in JSON-LD format and then use graph queries to get data back???
lfeagan
2016-06-01 07:56
@mart0nix: Yes. My proposal does not use JSON-LD at present. I store a compact pointer to the graph edge vertices as part of each transaction in the database. This helps to quickly traverse while inspecting the value(s) at each vertex.
mart0nix
2016-06-01 08:00
@lfeagan: any thoughts on using transaction event logs as a pseudo data layer ?
mart0nix
2016-06-01 08:00
I made some progress with that approach with Ethereum
mart0nix
2016-06-01 08:00
they are using bloom filters to store indexed event logs
mart0nix
2016-06-01 08:00
one can have as many event logs per transaction as needed
mart0nix
2016-06-01 08:01
and since one business transaction = one blockchain transaction
mart0nix
2016-06-01 08:01
I use the event logs to log key:values
mart0nix
2016-06-01 08:01
and the transaction itself as the container
lfeagan
2016-06-01 08:07
It isn’t a bad approach. And the new direction I am headed in is similar. For example, I also use the transaction as the container. I had an additional constraint to create a more cryptographically secure datastore, so that required some architectural fancy-footwork. I also wanted to create something that would work with WORM media, which was more of a personal pet-project to create something that would support some physical integrity protections as well.
mart0nix
2016-06-01 08:11
I see
mart0nix
2016-06-01 08:11
hyperledger DOES support event logs right ?
mart0nix
2016-06-01 08:12
and not only pub/sub for new ones but a client can scan older events as well ?
lfeagan
2016-06-01 08:26
Yes.
mart0nix
2016-06-01 08:31
awesome
mart0nix
2016-06-01 08:31
and is there something like getTransactionReceipt(trans_hash) which will also return all event logs produced by the transaction?
lfeagan
2016-06-01 08:35
Good question. I don’t know the answer.
mart0nix
2016-06-01 08:39
well if I can find the transaction protocol description, we may know the answer
mart0nix
2016-06-01 08:39
where can I find the transaction header specs ?

I have turned to the bluemix version of fabric and stop trying to deploy on AWS EC2
tribbloid
2016-06-02 18:06
so far so good
tribbloid
2016-06-02 18:07
but now I have another problem trying to write chaincode extension:
tribbloid
2016-06-02 18:07
fabric/vendor has some dependency missing
tribbloid
2016-06-02 18:08
there is no fabric/vendor/github.com/tecbot/gorocksdb
tribbloid
2016-06-02 18:08
while its being referred in vendor.json, the actual directory and files are not there
tribbloid
2016-06-02 18:09
can it be that the vendor manager is smart enough to download it automatically
tribbloid
2016-06-02 18:09
but I haven't enable this feature yet?
tribbloid
2016-06-02 18:12
Also, in the only chaincode example
tribbloid
2016-06-02 18:12
some of the import also points to non-existing project files/dependencies:
tribbloid
2016-06-02 18:13
import (
"hyperledger/cci/appinit"
"hyperledger/cci/org/hyperledger/chaincode/example02"
"hyperledger/ccs"
)
tribbloid
2016-06-02 18:15
how do I download cci and test the example?
ghaskins
2016-06-02 18:33
@tribbloid: note that you are looking at the chaintool example. You probably meant to look at the standard examples here...
ghaskins
2016-06-02 18:38
Hyperledger/cci namespace is synthetic, that's why you can't find it
tribbloid
2016-06-02 18:56
Thanks a lot. You are right, I stumbled on chaintool which are not part of the main project. Problem solved
tribbloid
2016-06-02 18:57
Though I still need to find the gorocksdb vendor package
ghaskins
2016-06-02 19:08
ill see if I can put better documentation in place (thinking README.md files in the example folders) so that doesn’t happen again
ghaskins
2016-06-02 19:08
as far as gorocksdb, that sounds strange...

Greetings, Vinnie Falco from Ripple here. I'd like to offer our new open source library *Beast* for your perusal: https://github.com/vinniefalco/Beast its got C++/Boost implementations of the HTTP and WebSocket protocols which come up often in decentralized software. We plan on deploying this code for Ripple to replace our aging third party websocket implementation. Perhaps this code could be of use to hyperledger projects? I'm the principal architect so if you have questions or need support, ask away (preferably here: https://github.com/vinniefalco/Beast/issues) Thanks!

Hi, trying to learn as much as possible in relation to Fabric. I've been using the sample applications that IBM have built to get up to speed. I notice that IBM haven't committed any changes to GitHub for a few weeks, are these built using the current version of the hyperledger fabric?
paulx
2016-06-06 05:41
Also on IBM's sample 'commercial paper' application, I have been running this on Bluemix which works ok. If I was to clone my current code base and config, and run another instance on my computer, another Bluemix account or simply another Bluemix region should these all bind together and act as peers in the network?

Hi @paulx, I am not sure I follow your questions entirely…. When you are asking about updates from IBM, are you looking for updates on a particular application or are you talking about the fabric itself? If you are looking at the Fabric itself, IBM’s view over the last couple weeks has been stablization especially around PBFT. I have been posting in the technical-discuss channel every other week on what IBM’s focus areas are just as a head’s up and to invite any feedback that I can give the IBM team. However, that is just an IBM view, I would invite others to do the same as what I really want is more community collaboration, so any areas that the community feels should be focused on we could really focus on together and knock down some big items.

error message is "Error unmarshalling chaincode request payload: json: cannot unmarshal object into Go value of type string"
i'm new to golang, so not sure where i am going wrong with the JSON format
i can see in IBM's cp web application that they use a JSON.stringify function, but not sure why the REST API isn't accepting this format

The changes to existing state is not persisted but hold in StateDelta in memory. will the data be lost if all validting peers crashed? https://github.com/hyperledger/fabric/blob/master/core/ledger/statemgmt/state_delta.go
ibmamnt
2016-06-07 07:50
I guess if all peers crash during the process of transaction (may be during consensus), the data will not persist. I may be worth while to seperate peers to diffrent avaiability zones and diffrent data center (in case peers are hosted on cloud). I don't think data center crashes at the same time.
starsheriff
2016-06-07 08:09
@middleton: yes, just looked at it. didn't notice that it is written in Python (and didn't expect it actually). I'm quite fluent in Python since I maintain a large codebase here at my work so the entry might be easier than the fabric project. I'll follow the projects and see what I can do and what catches my attention.
starsheriff
2016-06-07 08:13
In general I'm still trying to get my head around on how the hyperledger project as a whole works and how pieces fit together. Intel brought in the sawtooth lake project, IBM and DAH the fabric codebase. Is there any bigger scheme for the hyperledger project as such or will it be a collection of more or less independent projects pushed by the respective supporters?

@starsheriff: I share your views, we need some kind of roadmap which tells us where we are at the moment and where do we want to take this. Another thing, for us to build the community around this..we will need to simplify things a lot. For example...some kind of induction program for guys new to blockchain, go lang, etc. specific to HL where they can quickly come up the learning curve to enable them to contribute back to the project.

I was told that IBM OBC was a good choice for us, and I'm barely at the beginning of my research... Is IBM OBC somehow "deprecated" now? Is HyperLedger fabric the thing I should be looking for? Am I getting it right?

Hi all, for the application level access control in ChainCode, the existing examples in hyperledger such as asset management make use of TCert to judge whether a user is the owner of an asset. While from the documentation, we know that TCert is a short-term certificate and a user will use different TCerts in different transactions. Is there any other way to identify the transaction call's identity or what’s the right way to identify the transaction caller’s identity in hyperledger? Will be appreciated for your reply!

Thanks @markparz , what about running multiple Blockchain services under the one Bluemix account? The reason I ask is that the current Bluemix service is great for demonstrating applications, but it doesn't really provide a distributed network. Work in progress I guess

@nkunkel: I know that example02 has a response in its query operation
nkunkel
2016-06-07 21:31
So for instance this block:
if err != nil {
jsonResp := "{\"Error\":\"Failed to get state for " + A + "\"}"
return nil, errors.New(jsonResp)
}
nkunkel
2016-06-07 21:32
Just by returning it, I'll get jsonResp as a response in my client?

Question...How can we change the log level of REST APIs? It seems there is no setting in core.yaml.
ghaskins
2016-06-08 00:27
@nkunkel: note that both invoke() and query() return a [resp, error] tuple
ghaskins
2016-06-08 00:27
you can put whatever string you want in resp, and you can return any golang::errors object for error
ghaskins
2016-06-08 00:28
so, if you want to change the error, formulate whatever you want in the errors field….

Hi, how is it that in IBM's Bluemix blockchain service, all of the payload is shown in clear text in the blockchain tab? when you query a block from the swagger API it is encrypted, but on their blockchain tab everything is decrypted

Ok thanks @markparz , I can't see any REST API's that would enable you to bind an new peer to the network. The network API provides a list of current peers, but doesn't seem to allow you to bind new peers. What functions does the IBM Blockchain initiate the network with the two validating peers?
ghaskins
2016-06-08 21:59
@paulx: I think that support is only emerging, also note that this is not trivial on a permissioned network
paulx
2016-06-08 22:01
Thanks @ghaskins, yes I imagine that it is still a work in progress, just interested to see how IBM managed to get it to work. I imagine it's a discovery process whereby the config of the peers all point to an initial node and send a sync message to discover anything else on the network
ghaskins
2016-06-08 22:02
not quite, I think its all based on apriori configuration
ghaskins
2016-06-08 22:02
there is the notion of a “root” but that isn’t used in the same manner as you might expect in a permissionless network
paulx
2016-06-08 22:07
I guess what you're saying is that by no 'root' there is no dominate node, besides of course the first node that's created?
paulx
2016-06-08 22:20
@ghaskins: you mentioned that 'it's all based on appropriate configuration' - any suggestions on what specific config I need to setup to enable peers to connect? I've been basing all my learnings off IBM's sample apps on Bluemix , but guessing I should spin up my own local instance as it's probably easier to configure

@paulx: You can try running a peer and point it to one of the peers on bluemix as its root discovery node. Also use one of the validator (type 4, I think) credentials provided on the peer and point it to the CA (membership services) provided on bluemix. You will have to make your peer reachable from the internet and set the CORE_PEER_ADDRESS accordingly as other peers will have to communicate with it

: Hello Guys, anyone knows currently how the ledger is synchronized between VP nodes and NVP nodes? I noticed if a VP node joint a cluster later than others, the height of the ledger is different with the others, and there is no ledger on NVP nodes at all?
kletkeman
2016-06-13 03:46
@leizh1984: The NVP has no ledger and no world state. It is essentially a gateway to the fabric for applications using gRPC or REST. It can also accept event subscriptions.
ulysses
2016-06-13 03:55
@leizh1984: To quote the fabric documentation: "Peers maintain an up-to-date copy of the blockchain, but in contradiction to validators, they do not execute transactions (a process also known as transaction validation)".
ulysses
2016-06-13 04:01
@leizh1984 Apparently, all the nodes (validators, peers) send out DISC_HELLO message whose payload is a Hellomessage object containing its endpoint. If the block height received upon DISC_HELLO is higher than the current block height of the peer, it immediately initiates the synchronization protocol to catch up with the network.
leizh1984
2016-06-13 04:06
@ulysses: well technical it should be like this, but the problem is in the environment I have, the ledger isn't sync as it should be, so I'm checking if it is just a direction but not achieved or there is something wrong with my setting.
here is the network peer status:

@ulysses: and about NVP, it only says it doesn't execute the code, according to glossary.md, the NVP should maintain a local copy of the ledger as well,
Non Validating Node (Peer) Purpose: Constructs transactions and forwards them to validating nodes. Peer nodes keep a copy of all transaction records so that solution providers can query them locally.
Key Roles:
1) Manages and maintains user certificates issued by the membership service
2) Constructs transactions and forwards them to validating nodes
3) Maintains a local copy of the ledger, and allows application owners to query information locally.
Owned by: Solution Provider, Network Auditor
leizh1984
2016-06-13 04:14
@ulysses: even NVP is a gateway, it should be able to query the information of the ledger, if it doesn't have the ledger, the query can't be done either;

@ankitkamra: the port number 443 looks strange: 172.17.0.2:443

@bryan-huang: I have used 5000 port too in that case one of VP from two gets crash.
can you please help me to resolve the same.
bryan-huang
2016-06-13 09:42
code: 'ECONNREFUSED’, seems the port cannot be connected, make sure the service was started, you can try telnet the ip port first
ankitkamra
2016-06-13 09:44
@bryan-huang: it is not listening on 443 port. so i changed that port to 5000 by default application runs for https but on 5000 port it is listening for http that's why peer gets crash

There are currently two incubator projects under the Hyperledger umbrella: Fabric and Sawtooth Lake. They seem to be independent to each other and functionally somewhat overlapping. Can they be integrated together? Apologize if this is a silly question.
cbf
2016-06-13 15:28
correct
cbf
2016-06-13 15:29
as for integrating the two, I know that there are some looking and interested in seeing what that would entail - eg could we get POET running on the Fabric, or the PBFT running on STL
cbf
2016-06-13 15:29
nothing formal has been proposed as of yet
middleton
2016-06-13 15:49
@burnabybull: in addition to what @cbf mentioned, the business logic layers are also complementary... Fabric uses Chaincode in Dockers and Sawtooth uses Transaction Families deployed to the validators. Cross-pollinating those layers could also be interesting.

hi I have a specific question....Can the transactions be replicated to selective nodes only and not all the nodes.For example if Bank A and Bank B did a transaction the data is copied only to A and B's node and other Bank's node.
vikasjakhar
2016-06-13 16:38
The banks will not like their data to be shared with unrelated banks even if the data is encrypted
ghaskins
2016-06-13 16:46
@vikasjakhar: what you are describing is called “confidentiality” in Fabric parlance. Not sure about other projects
vikasjakhar
2016-06-13 16:58
@ghaskins: So it it possible in Fabric to replicate data to certain nodes only based on some rules ?
ghaskins
2016-06-13 16:59
yes, or at least it will be when the spec is realized
ghaskins
2016-06-13 16:59
confidentiality will allow you to set the scope on data/execution within the chain
vikasjakhar
2016-06-13 17:04
@ghaskinscan you point me to any documentation around confidentiality
jeremysevareid
2016-06-13 17:08
@ghaskinscan @vikasjakhar There's an architecture WG proposal that taps into some of this: https://github.com/hyperledger/fabric/wiki/Next-Consensus-Architecture-Proposal
jeremysevareid
2016-06-13 17:10
@ghaskinscan @vikasjakhar it's sometime referred to as selective disclosure in Identity WG meetings. Companies like zcash and iconic are interesting reference points.

Me too - needs info on chaincode - is there a container which hosts all chaincodes ever submitted? But this container is not shown in the Architecture diagram
cbf
2016-06-14 12:29
@venkat_reddy: chaincode is stored in the blockchain for runtime - but the vision would be that there would be analog of dockerhub or npm for chaincode sharing/distribution
cbf
2016-06-14 12:29
right now, it’s git(hub)
cbf
2016-06-14 12:32
essentially it is what the fabric calls a smart contract
venkat_reddy
2016-06-14 12:36
@cbf: Thanks a lot for the pointers!. Yeah - I meant hosting of chaincode at runtime only. So I guess this is an enhancement to a standard blockchain (which typically contains only transactions). But my question is - will there be a daemon kind of service/container which always goes around all chaincodes, and executing them all the time?
cbf
2016-06-14 12:42
ah, no, if the container isn’t running when a transaction comes in, the peer (re)starts it
venkat_reddy
2016-06-14 12:49
Is there any language to express a SmartContract? For example, humans and courts can understand the contrasts written in English (well, legal English). How about smart Contracts?
cbf
2016-06-14 13:01
currently we support go as te chaincode language… there is a project underway to develop java shim and theoretically we can support any language or dsl
cbf
2016-06-14 13:02
there has been some discussion of use of contract standards such as legalxml
cbf
2016-06-14 13:02
or xbrl
venkat_reddy
2016-06-14 13:13
@cbf: Thanks again. May be some tempting language with just enough syntax (such as the XML standards you have mentioned) to describe a contract should be good enough, I think.
venkat_reddy
2016-06-14 13:16
So the chaincode is replicated across all validating nodes, and so all nodes will start executing it when a certain time-based trigger goes off within the contract? Apologies for my newbie questions!

How can I make the requst go to both validators for consensus
muralisr
2016-06-14 14:42
@vikasjakhar: chaincode needs to be launched for each peer. The dev mode doc refers to one node config with “noops” consensus. If you are launching multiple nodes, in dev mode, you have to launch one instance of the chaincode per peer

Sawtooth is a modular blockchain built for scalability and to support pluggable components at each layer, e.g. consensus. It has a few novel aspects including the default consensus (PoET) and the transaction family concept in the business logic layer (smart contracts if you like that term).
middleton
2016-06-15 15:23
Fabric is also modular and includes an experimental consensus (seive) and transaction logic deployed on chain executed in dockers (chaincode).

Hello guys, I've been reading some of the Hyperldger Fabric documents. It looks really robust, but I don't see much talking about currencies or assets. I know fabric is designed as a _general_ purpose blockchain framework, but is it not a suitable choice for developing cryptocurrencies? What if I want to implement an incentivized blockchain network? Can Fabric provide such functionality? Is Sawtooth maybe a better choice?... What do you think?
kelly
2016-06-15 18:17
Fabric is for permissioned usages
kelly
2016-06-15 18:18
so not the best for open cryptocurrency
kelly
2016-06-15 18:18
@cbruguera: sawtooth does not currently have incentives, although an upcoming release will likely include them
kelly
2016-06-15 18:19
the 'marketplace' transaction family that runs on top of sawtooth allows for assets to be issued and exchanged
cbruguera
2016-06-15 18:26
Thank you @kelly !
cbruguera
2016-06-15 18:28
Then, a bit off-topic now, and please excuse me... Is there any other blockchain framework/platform on your mind where I can easily implement a network with native assets and incentivized protocol?
kelly
2016-06-15 18:36
maybe multichain?
kostas
2016-06-15 18:39
@kelly: Multichain does native assets but I fail to see how there's an incentivized protocol there?
kelly
2016-06-15 18:39
afaik it's based off bitcoin
kelly
2016-06-15 18:39
so I assume that the 'mining reward' is still an option
kelly
2016-06-15 18:39
I've never used it though
kostas
2016-06-15 18:40
it's a bitcoin fork for a whitelisted set of participants without PoW and with a mining scheme called mining diversity
kostas
2016-06-15 18:40
there is no incentivized protocol
kelly
2016-06-15 18:41
ah gotcha
kelly
2016-06-15 18:41
what's that? multi-sig block signing?
kostas
2016-06-15 18:41
a simple round-robin scheme for who the leader is
kostas
2016-06-15 18:41
the thinking is that even if the next guy is a jerk and censors my transactions, eventually we'll switch to someone who doesn't
kelly
2016-06-15 18:42
gotcha

Hey! Thank you very much for the answer. I'll check out that.

turn debug logs on, there might be a more descriptive message ... usually, it's some kind of network config issue, not resolving hostname, wrong port, etc ...

greetings. what is the scope of hyperledger ?. Is this essentially a blockchain project, or should/could it include related immutable technologies. I think "something else" should probably go somewhere else, but I have an overlapping problem space I think, so this may be the right place to discuss

does/will sawtooth have a streams concept. I want a select group of parties to be able to findOrCreate a hash on a contract specific wallet, for those parties to be able to verify that all others have signed, and for external parties to also be able to verify that the entry has been signed. Is this a pattern you are working on or have.

2016-06-17 18:17
@mark_lester: within sawtooth, that would be implemented as a transaction family. in a transaction family, you define the transaction data and then validation and storage-update functions (is_valid/apply) to update the local store. I don't believe we have any transaction families as examples in which multiple participants sign an object; but generallly, you could have a transaction which created the object and subsequent transactions (from different participants) for signing it, and then a client application which could inspect local state (for external parties)
amundson
2016-06-17 18:19
@mark_lester: I just added a tutorial on transaction families to our docs - https://intelledger.github.io/ - which should help as an overview
mark_lester
2016-06-17 18:31
@amundson: thanks. a pre req is clearly to understand marketplace I guess
amundson
2016-06-17 18:37
@mark_lester: it is certainly the most complex/complete transaction family available currently. it may or may not be a good basis for what you want to accomplish, depending on whether the concepts in mktplace coorelate to your desired goals. the core concepts are also available sawtooth-arcade's tic-tac-toe example transaction family, without as much business logic
amundson
2016-06-17 18:39
(I used concepts twice there, first use was about business logic and the second use 'core concepts' was about transaction families)

i assume obfuscation of wallet addresses is considered intractable. you just have to accept that your opponents will perform traffic analysis on their validations and at the least determine a map of your connectivity and relative growth

hey @cbf , I am trying to get to the bottom of this I guess https://blog.ethereum.org/2016/01/15/privacy-on-the-blockchain/ . The system I built is essentially doing paragraph one of "stepping down". I'll try and absorb that doco, it looks pretty big. Ah, so the idea is that we use chaincodes and run a different consensus strategy, one that uses only contract members.

is there any concept of negotiation of a contract. my input spec was that the insurers needed to cook up bespoke rules depending on stuff like sales tax in kentucky etc, and so they need to dynamically add and agree rules. indeed they need to agree what the fields and structure of the thing is. so we have a system where this contention is resolved socially ,e.g. two tried adding a field called Name at exactly the same time, or when the contract is in a "live" state to apply a value. One of them has to manually back off though in most cases there will have been access rules applied so only one party would be able to do it.

@huhaiqing: Recommend to use "od" (octal dump) since the payload itself is recorded in gRPC format.

001 means there is 1 character, say "a", 002 means 2 bytes e.g. "10".

@huhaiqing: If the peer runs with normal mode (i.e. without --peer-chaincodedev option), then "peer" process will spawn new container to run chaincode, and the new container will store the chaincode (source code) under $GOPATH folder, and build and execute it. If peer spawns the docker image it will come with the name similar to "dev-<peer-name>-<chaincode-id-name>. You can inspect this docker contaier with "docker exec". For example, you can run "ps -ef" command like:
```$ docker exec dev-vp0-ea192f54467d957e98a4973b74cb8093847deac9a362928fb07334ce096f9d851fb59027e79bdaa0f119d0585c2045a020424cedc312175f5d91f03e66c84c62 ps -ef

@yacovm. The chaincode print out message to stderr, so you need to inspect logs of chaincode docker running container.
```$ docker logs dev-vp0-ea192f54467d957e98a4973b74cb8093847deac9a362928fb07334ce096f9d851fb59027e79bdaa0f119d0585c2045a020424cedc312175f5d91f03e66c84c62 2>&1 | grep Amount

Hey All
cloud.strife
2016-06-20 18:13
is it possible to remove chaincode so that we can reduce the amount of docker containers, if the chaincode is no longer needed?
muralisr
2016-06-20 18:14
@cloud.strife: you can do “docker rm….” on the containers
muralisr
2016-06-20 18:15
there is no “destroy” symmetric to “deploy” currently
cloud.strife
2016-06-20 18:16
@muralisr: yes this will remve the containers, but will the hyperledger peer have issues trying to connect to it for whatever reason?
cloud.strife
2016-06-20 18:16
or as long as the chaincode is not in use, it will be OK?
muralisr
2016-06-20 18:17
on the next invoke/query, hyperledger will/should bring it up automatically
cloud.strife
2016-06-20 18:17
as in no request come in to invoke anything for that chaincode id
cloud.strife
2016-06-20 18:18
also what is the supported docker version? I see some errors in the docker logs: DEPRECATED: Setting host configuration options when the container starts is deprecated
cloud.strife

@kostas DARPA is interested in building a messaging app backed by blockchain. For secure messaging.
hart.montgomery
2016-06-21 18:38
You could probably write a secure messaging app with good privacy/anonymity properties using a blockchain, but it would come at the expense of a huge amount of (compared to normal messaging services) extra data storage requirements.

How to create a new user in Hyperledger fabric?
tribbloid
2016-06-21 23:18
I just tried the enrollment API:
tribbloid
2016-06-21 23:19
HTTP POST https://.....http://blockchain.ibm.com:443/registrar
{
"enrollId": "new_user",
"enrollSecret": "random_password"
}
tribbloid
2016-06-21 23:19
and I got this:
tribbloid
2016-06-21 23:19
HTTP/1.1 401 Unauthorized
{
"Error" : "rpc error: code = 13 desc = 'server closed the stream without sending trailers'"
}
tribbloid
2016-06-21 23:20
It looks more complex than I expected, involves offline configuration and pluggable proof-of-identity components

Is there a limit of block size in Hyperledger? We know that is 1MB in Bitcoin. Thanks
ibmamnt
2016-06-23 09:06
I'm also curious about size limitation. I'd like to see the wiki page for possible limitations to understand the architecture better. As for the size of block, it may be 64MB, since this is hard coded in google's protocol buffer impl.
> static const int kDefaultTotalBytesLimit = 64 << 20; // 64MB
ibmamnt
2016-06-23 09:10
By the way, size of block varies, depending on consensus model. In case of noops, the max number of transaction per block is 500.
ibmamnt
2016-06-23 09:11
> consensus/noops/config.yml
> block:
> # Number of transactions per block. Must be > 0. Set to 1 for testing
> size: 500
ibmamnt
2016-06-23 09:13
In case of pbft, the default value is "2" in batch mode. I guess this is a kind of trade off of consensus speed and block creation.

@clessor: stl has PoET as its consensus algo… Hyper right now has pbft and noops
simon
2016-06-23 13:52
noops is no consensus algorithm
cbf
2016-06-23 13:52
I think one major difference is how the two deal with permission. Fabric is primarily designed to handle a permissioned network of peers, where STL supports permissionless. Also, STL has innovated around consensus and created POET (proof of elapsed time) where Fabric is focused on PBFT and a derivative we call Sieve
cbf
2016-06-23 13:53
we also have different approaches for 'smart conteacts'
codascud
2016-06-23 13:53
@simon: correct… just mentioning...
cbf
2016-06-23 13:53
note that the two are not in competition... this is not a bake off, but we are looking for synergies between top level projects
codascud
2016-06-23 13:55
@cbf: In case I want to use PoET (which is written in Python) in Hyperledger, does it mean I will have to rewrite it in go using Hyper using Consensus Framework?
codascud
2016-06-23 13:55
Or is there a way I can call consensus algo written in other languages form go?
ghaskins
2016-06-23 13:59
@codascud: the consensus portion is abstracted to a degree, though the focus has been on alternate golang based impls….im sure with some extra work that could be extended to something external
ghaskins
2016-06-23 14:00
for instance, I think in many cases, the interface is message based and using protobufs, both of which are conducive to language neutrality
ghaskins
2016-06-23 14:00

@codascud: hyperledger is the umbrella project, which contains fabric and sawtooth. PoET is in sawtooth and thus, you can already use "hyperledger" with PoET. But I think what you mean above is integrating PoET with fabric, not hyperledger.

Understood. At any rate, we have a problem in the sense that we're using this tool to exchange valuable technical info that we cannot retrieve after a while. The powers that be can always respond with "deal with it", but I hope that someone understands that this is a problem and is looking into ways to fix. (Whether that means paying for the service, or switching to an alternative, I do not know.)

What exactly is a chaincode? A smart contract or an interactive web application?
By smart contract, I mean an agreement between multiple parties, that executes transactions (asset transfers) autoamtically based on events over a span of time. A web application is similar to an online flight booking system.
So which one is chaincode?
kostas
2016-06-25 12:52
A chaincode is a smart contract, aka logic/script that you install on the blockchain.
venkat
2016-06-25 12:56
Can it be a backend (business logic) for an interactive web application?
venkat
2016-06-25 12:57
supporting CRUD for some business objects?
kostas
2016-06-25 12:57
Although, to go back to your example -- theoretically nothing could prevent you from writing an online flight booking system using a chaincode... (It really doesn't make sense. I'm just saying it's technically feasible.) Isn't an online flight booking system an agreement between Delta and you that if you pay them $200 they will give you a ticket to fly to New York? In that sense, you are giving them a token and you get a token back in return. Delta could add tokens (new available tickets) to the chaincode periodically, and you could retrieve them by giving to the contract the tokens that it asks for in exchange.
kostas
2016-06-25 12:58
^^ See comment above.
kostas
2016-06-25 12:58
What you need to ask yourself though is not whether you can do something on a blockchain, but *why*. For instance, it doesn't make any sense for Delta to set such a system up.
venkat
2016-06-25 13:01
But what about the blockchain as application platform? Ethereum and HL might be seen as one. And the chaincode sports full-fledged programming support, not just minimal templates for contracts
kostas
2016-06-25 13:02
This answers the "can it be done" part. It doesn't answer the "why should it be done" part.
venkat
2016-06-25 13:03
People are assuming that they can move applications onto blockchains
kostas
2016-06-25 13:04
For some applications it may make sense, for others it most definitely doesn't.
venkat
2016-06-25 13:05
You mean contract-focussed application? which are not latency sensitive and doesn't care about scalability?
kostas
2016-06-25 13:05
I do not understand the meaning of a contract-focused application. Too vague.
kostas

Too broad of a definition.
kostas
2016-06-25 13:07
It might be the right definition, but you cannot get a blanket statement on whether it makes sense to transfer all of these applications within that domain to a blockchain-based system.
kostas
2016-06-25 13:07
It all depends on the context, which is particular to the application.

kostas

(IIRC, Gideon's against smart contracts in general. But you can certainly use them if you think they make sense.)
venkat

Ofcourse, you only said that it could be a good starting place, which means you didn't say it relates to smart contracts.
venkat

Since I kind of digested those plain blockchain usecases, how do I go about learning about HL use cases (smart contracts) in a real business world?
kostas
2016-06-25 16:16
That's a good question. It's been a long time since I read it, but maybe this could be a starting point: https://github.com/hyperledger/fabric/blob/master/docs/biz/usecases.md
venkat
2016-06-25 16:21
Hmm... that page mentions smart contract only once, and chaincode thrice. Let's hope it really sheds light on smart contract-based use cases

venkat
2016-06-25 16:32
That page, for example, talks about contracts, but they seem very different than something to be implemented by chaincode
muralisr
2016-06-25 16:39
@venkat chaincodes are more implementation detail of those higher level use cases. I wouldn’t look for 1-1 mapping between the use-cases and chaincode. Some of the use cases go into details of what problem the blockchain approach will solve and from those details will emerge the implementation of various parts of the stack right from the “application” layer on top to the “chaincode”.
venkat
2016-06-25 16:45
Thanks @muralisr. Does that mean there is no 1:1 mapping between smart contracts and chaincodes? If yes, is a smart contract to be implemented by a collection of chaincodes?
venkat
2016-06-25 16:46
Just trying to understand the structure and relations between Application, Smart Contract and Chaincode
muralisr
2016-06-25 16:51
Sure. Chaincode is truly an implementation artefact while a smart contract - in my view at least - a higher level construct. VERY loosely, I’d think of “smart contract is to chaincode” what "DB app is to stored procedure” ? In some cases DB app IS the stored proc but in most bigger and more abstract
muralisr
2016-06-25 16:53
I’d hasten to add all the above is “in a manner of speaking”
amundson
2016-06-25 16:56
the relationship is similar to that between sawtooth's transaction families and smart contracts as well (transaction families as a detail of how one would create smart contract implementations)
jamie.steiner
2016-06-25 16:56
are there any documented examples of chaincode?
venkat
2016-06-25 17:04
I'm seeing entire applications being built out of a single chaincode by exposing all CRUD operations through Invoke, on the domain objects (types, structs). Is this pattern intended?
muralisr
2016-06-25 17:05
@jamie.steiner: there are some examples under https://github.com/hyperledger/fabric/tree/master/examples. Hopefully will be more in future
muralisr
2016-06-25 17:06
@venkat: you mean a monolithic all-contained app directly in the chaincode - basically a client/server topology ?
venkat
2016-06-25 17:13
Yes. thats where I'm having trouble seeing a smart contract in there.
venkat
2016-06-25 17:14
Then I thought HL is an application platform
venkat
2016-06-25 17:14
which justifies the case
venkat
2016-06-25 17:16
and chaincode is THE application?
middleton
2016-06-25 17:21
HL is a family of distributed ledger technologies. When you are looking at Frabric, the Chaincode is your transaction logic. An app in my mind would be something like a client submitting transactions onto the ledger.
venkat
2016-06-25 17:26
If client is submitting transactions into the ledger, what else is chaincode doing?
middleton
2016-06-25 17:27
processing the transactions
venkat
2016-06-25 17:28
Isn't that processing done by peers in a generic way? For example, a bitcoin client submits transactions. No chiancode needed to process them.
middleton
2016-06-25 17:28
[client]---submit tx-->[chaincode]--run tx rules-->[ledger]--commit result--|
middleton
2016-06-25 17:29
in bitcoin utxo ~ chaincode.
venkat
2016-06-25 17:30
so chaincode defines the output of a transaction. Is that about right?
venkat
2016-06-25 17:33
In other words, can we say that bitcoin system has a single in-built chaincode operation (transfer money)?
middleton
2016-06-25 17:37
sure :slightly_smiling_face:
middleton
2016-06-25 17:37
bitcoin is very tightly coupled
middleton
2016-06-25 17:38
fabric and sawtooth have modularized concepts so the division between layers is more clear. This is intended to promote pluggable features.
middleton
2016-06-25 17:38
If for example UTXO is insufficient you can use chaincode, or if proof of work isn't the right fit then plug in PoET.
venkat
2016-06-25 17:39
Sorry - haven't explored sawtooth yet. Mind telling its role, in brief?
middleton
2016-06-25 17:41
Sawtooth is another ledger platform.
middleton
2016-06-25 17:41
Its architecture is roughly client --> transaction family --> validator
middleton
2016-06-25 17:42
The marketplace client and marketplace transaction family give example transaction behavior running on top of the core validator (i.e. miner) which is running a consensus algorithm called Proof of Elapsed Time.
venkat
2016-06-25 17:44
The PoET sounds really nice, atleast from environmental view point. Will read about the other things you said.
middleton
2016-06-25 17:44

jamie.steiner

PoET - that's the one that requires trusted, vendor specific hardware, right?
amundson
2016-06-25 18:50
@jamie.steiner: it does use a TEE (such as SGX) - https://intelledger.github.io/introduction.html#proof-of-elapsed-time-poet
middleton
2016-06-25 19:43
All good questions @venkat :)
jamie.steiner
2016-06-25 19:50
@middleton: about pluggability - I don't really get the statement that "If for example UTXO is insufficient you can use chaincode" - it seems like these are orthogonal concepts, if chaincode is, roughly speaking, smart contracts (ie. user deployable, event driven logic).
middleton
2016-06-25 20:26
Hi @jamie.steiner. I mean they are different rule sets for authoring txn logic. I'm less familiar with chain code, but with sawtooth txn families there's no reason you couldn't make a UTXO family. In fact that sounds like kind of a fun project.

from the answers I got, it seems that a smart contract is implemented by a set of transaction types (or families) and an application is something that invokes a set of transactions over time.
venkat
2016-06-27 06:08
And that a transaction type (or types) is implemented by a chaincode
venkat
2016-06-27 06:13
What's still missing in my understanding is the composition and aggregation (or overlap) across these 3 terms (contract, app, chaincode). Whether same chaincode can support multiple apps and contracts, and whether a contract is fully contained inside and app etc.

jamie.steiner
2016-06-27 17:08
Still trying to wrap my mind around chain code - is it code that can be deployed, by users, into the blockchain, in order to extend a given blockchain's functionality, or is it better described as a set of transaction definitions and validation logic. I guess the main difference I am wondering about is whether you can deploy chain code to the blockchain, on the fly - like ethereum smart contracts.

Ive read through the examples, and, while I can't claim to understand them fully, my question is more around how chaincode gets deployed, than what it is. In ethereum, a smart contract is represented by bytecode, and any user can author brand new contracts and deploy them. The byte code for that contract is recorded in the ethereum blockchain, and is executed by miners. I'm wondering if chain code works the same way - ie. can a user, or validating node, author chain code, and inform other nodes that now it exists, and update the blockchain with this new business logic that will, henceforth, be executed by the other validating nodes.
simon

2016-06-27 17:20
@jamie.steiner - basically yes - this is called a "deploy" transaction
simon
2016-06-27 17:21
@jamie.steiner: why do doubt that?
garisingh
2016-06-27 17:21
basically, the code is packaged up in a portable Docker tar.gz file which is distributed to all of the nodes and deployed a a container
garisingh
2016-06-27 17:22
https://github.com/hyperledger/fabric/blob/master/sdk/node/lib/sdk_util.js#L119 shows how the code package is created
jamie.steiner
2016-06-27 17:23
hmm, ok. interesting.
jamie.steiner
2016-06-27 17:24
thanks - I will need to dig deeper, i see
jamie.steiner
2016-06-27 17:25
it means that the validating node must have access to a go compiler
jamie.steiner
2016-06-27 17:27
how is the chaincode sandboxed from the host OS?
simon
2016-06-27 17:27
well it is in the docker container, but that's it
simon
2016-06-27 17:27
i opened an issue about sandboxing long ago
jamie.steiner
2016-06-27 17:29
is chaincode restricted in anyway, or can it be arbitrary golang?
codascud
2016-06-27 17:33
@jamie.steiner: I wont say “restrictive” rather it requires implementing the chaincode interfaces...

is fabric chaincode pretty much the same as IBM Bluemix chaincode?
codascud
2016-06-27 17:41
yes
garisingh
2016-06-27 17:44
exactly the same. We use fabric for Bluemix
garisingh
2016-06-27 17:45
we just (attempt) to take away the pain of you needing to stand up your own network and give you a cool dashboard (full disclosure my team owns the BMX blockchain service so pardon the pseudo-marketing)
jamie.steiner
2016-06-27 17:50
not marketing - im glad for the comparison
greg_not_so
2016-06-27 17:59
has anyone registered BMX trademark yet? i couldn't find it here: https://new-console.ng.bluemix.net/docs/navigation/notices.html but i would recommend it if it's available for registration
vikasjakhar
2016-06-27 18:06
I have a question....does thr endorsement policy have to be static or can the chaincode choose the endorsers dynamically based on the data in the transaction?
nsubrahm
2016-06-27 18:14
Why does HL not have PoW algorithm?
jamie.steiner
2016-06-27 18:32
for example, chaincode, either in fabric, or in IBM Bluemix is not prevented from running things using `os/exec`
garisingh
2016-06-27 18:41
correct - chaincode can (although it shouldn't) do anything you can do in Go within a Docker container
ghaskins
2016-06-27 18:45
This will eventually be locked down, I imagine, at least within the constraints of what Docker is able to do
muralisr
2016-06-27 18:46
@vikasjakhar: so the question is about in the next generation consensus, can transactions against chaincodes be dyamically be directed towards a set of endorsers ?
muralisr
2016-06-27 18:50
by “dynamically” - different transactions to the same chaincode be endorsed by different set of endorsers ?
vikasjakhar
2016-06-27 19:06
@muralisr that is correct. Our requirement is to have endorsers dynamically selected based on transaction data

@garisingh: Thanks, I found that section. However it seems to still put the cc containers in `host` network mode. How do I ensure that the core.yaml is being loaded? Is there an ENV variable for this setting? I can confirm that all ENV variables I have set work properly. Is there a full list of ENV variables that I can view that pertain to different options in the core.yaml?

venkat
2016-06-28 08:19
I assume the outer oval is connecting different organisations (CCP, CSD etc)
buhrmi
2016-06-28 08:19
i think the outer oval has no meaning whatsoever
venkat
2016-06-28 08:20
oh, ok
buhrmi
2016-06-28 08:20
don't think it means "connection" ... probably just to group organizations visually
venkat
2016-06-28 08:20
And we have the users on the left (developer, network operator etc)
venkat
2016-06-28 08:20
which org do these guys belong to?
buhrmi
2016-06-28 08:21
actually i don't know. is this bluemix specific?
venkat
2016-06-28 08:21
Yeah. it looks like that
venkat
2016-06-28 08:21
And the nodes in the inner oval
venkat
2016-06-28 08:22
who owns and who provisioned them?
venkat
2016-06-28 08:22
The biggest question is -
buhrmi
2016-06-28 08:22
haha they are owned by whoever
venkat
2016-06-28 08:22
When I Create a network and a blockchain app/service
venkat
2016-06-28 08:23
the monitoring dashboard shows my nodes only
venkat
2016-06-28 08:23
as if the entire blockchain is only visible to me.
buhrmi
2016-06-28 08:23
the monitoring dasboard of bluemix?
venkat
2016-06-28 08:23
Then where is this shared ledger?
venkat
2016-06-28 08:23
Yes
buhrmi
2016-06-28 08:23
there is no shared ledger yet
venkat
2016-06-28 08:24
No shared ledger yet??:face_with_rolling_eyes:
buhrmi
2016-06-28 08:25
no .... i want to set up a "test network" but i don't have time / money
venkat
2016-06-28 08:26
So - it is just for you. nothing is shared?
buhrmi
2016-06-28 08:27
also, in the current version of "chaincode" - as far as i understand - it's easy to write malicious contracts that could take down the entire system. so opening up a shared ledger might not be a smart move at this time
venkat
2016-06-28 08:27
But that is the whole point of fabric, right? The Great Distributed Shared Ledger ???
buhrmi
2016-06-28 08:28
yeah i think when you create a blockchain using bluemix, you are using the certificate authority bluemix provides. so only u can use it
buhrmi
2016-06-28 08:28
well, eventually, yes ... it's just not ready yet
venkat
2016-06-28 08:29
Then I could as well use a EC2 elastic cluster with a replicated database such as mongodb, and that is just as good as fabric or better?
buhrmi
2016-06-28 08:31
ha
buhrmi
2016-06-28 08:32
yeah currently i don't know a good usecase for using blockchain created within bluemix
buhrmi
2016-06-28 08:32
it's a good playground for fabric
buhrmi
2016-06-28 08:32
to try it out before it - some time - might or might not evolve into the great ledger
venkat
2016-06-28 08:32
Got it. We can test chaincodes
buhrmi
2016-06-28 08:32
yes
venkat
2016-06-28 08:35
Even outside bluemix, who among the participant parties, creates chain codes and apps?
venkat
2016-06-28 08:36
for a shared workflow, for example
venkat
2016-06-28 08:36
may be a supply-chain case
buhrmi
2016-06-28 08:37
the answer would be "everybody who wants to"
venkat
2016-06-28 08:38
But it needs to be the same code for everybody
venkat
2016-06-28 08:38
because they all are sharing workflow and shame ledger data
buhrmi
2016-06-28 08:39
currently there is something called membersrvc involved, against which the potential users need to authorize against before being able to deploy chaincode
buhrmi
2016-06-28 08:39
yeah of course, every node should run the same code
venkat
2016-06-28 08:41
may be they will have a shared Git repo and commits go by majority vote?
jamie.steiner
2016-06-28 08:42
2/3 majority, of course..
buhrmi
2016-06-28 08:42
are you talking about the code for the blockchain or the chaincodes?
venkat
2016-06-28 08:42
chaincodes
buhrmi
2016-06-28 08:43
chaincodes are deployed via transactions ... so you submit a transaction to the blockchain saying "hey i wanna deploy this chaincode" and it gets deployed.
buhrmi
2016-06-28 08:44
no need for a shared git repo
buhrmi
2016-06-28 08:44
it will be "your personal" chaincode
venkat
2016-06-28 08:44
but what I was saying is there are multiple business partners who are participating in a business activity such as supply chain.
venkat
2016-06-28 08:45
and this activity will be defined by a set of chain codes which need to be agreed upon by all the participants
buhrmi
2016-06-28 08:45
yes ... the deployed chaincodes should be browsable
buhrmi
2016-06-28 08:45
and viewable
buhrmi
2016-06-28 08:45
and hopefully understandable
venkat
2016-06-28 08:46
And nobody should control the chaincodes
venkat
2016-06-28 08:46
as a authority
buhrmi
2016-06-28 08:46
that's the goal
venkat
2016-06-28 08:46
I mean modifications to the chaincode
buhrmi
2016-06-28 08:47
yes
venkat
2016-06-28 08:47
In that case we need a shared repo for the chaincode to reside
buhrmi
2016-06-28 08:47
currently it's not possible to change the chaincode after it has been deployed. somebody wanted this as a feature but i don't think its a good idea
venkat
2016-06-28 08:48
Ok - but what happens before deployment? I guess they all agree on a chaincode
venkat
2016-06-28 08:48
or a set of them
buhrmi
2016-06-28 08:49
no u can just deploy whatever ... what *should* be done instead is create a viewer (webapp or something) that can browse and view deployed chaincodes
buhrmi
2016-06-28 08:50
if somebody doesn't like your chaincode, they'll just won't interact with it haha
venkat
2016-06-28 08:51
Ah - ok
venkat
2016-06-28 08:51
so participants can pick chain codes to include into their apps
buhrmi
2016-06-28 08:52
that's as far as i understand it
venkat
2016-06-28 08:52
But it doesn't serve the use case of creating a contract or business activity which has some specific structure and flow.
venkat
2016-06-28 08:53
Choosing of chain codes shouldn't be left to the choice of participants
venkat
2016-06-28 08:54
Different orgs may have different apps and different chain codes, but they should all run in sync with each other
buhrmi
2016-06-28 08:54
i don't know, it might be that other people's chaincodes gonna be publicly callable
buhrmi
2016-06-28 08:54
don't know the plan for that
venkat
2016-06-28 08:54
yeah - things are in flux - don't know how it works on Ethereum
venkat
2016-06-28 08:56
Both Ethereum and Fabric should demonstrate a simple use case inovolving multiple businesses participating in a shared business activity through a shared ledger
buhrmi
2016-06-28 08:58
yeah i brought that up on the mailinglist
buhrmi
2016-06-28 08:59
it has sparked a private conversation with the hyperledger executive director but no conclusion on that yet

how do we monitor the fabric network? Say, how many peers are still active etc.
venkat
2016-06-28 09:43
The REST API doesn't seem to be enough for monitoring
venkat
2016-06-28 09:43
only blockchain height is available through REST
karthik
2016-06-28 09:47
karthik
2016-06-28 09:48
@venkat: Please refer to this REST endpoint
venkat
2016-06-28 10:01
ha - how did I miss this :open_mouth:
venkat
2016-06-28 10:01
Thanks @karthik
venkat
2016-06-28 10:01
So, that makes two metrics - block height and peers
venkat
2016-06-28 10:04
@karthik - does that Endpoint (network/peers) return all peers or just the ones known to the peer we are talking to?
karthik
2016-06-28 10:05
If you are a peer and connected to a network, this endpoint will list all the participating peers in that network.
venkat
2016-06-28 10:05
The docs say -
venkat
2016-06-28 10:05
The /network/peers endpoint returns a list of all existing network connections for the target peer node
venkat
2016-06-28 10:09
So, it could be just the ones known to the peer that is processing the REST request
simon
2016-06-28 10:09
the peers form a full mesh
venkat
2016-06-28 10:10
oh - does every peer connect to every other?
simon
2016-06-28 10:11
that's what i said
venkat
2016-06-28 10:12
Why would a peer maintain a connection to every other peer in a possibly large network? Is there some functionality which requires that?
simon
2016-06-28 10:13
the network is fixed size, and with the current algorithm, not very large
simon
2016-06-28 10:15
for a large network, you will have to develop a different consensus algorithm
venkat
2016-06-28 10:16
I thought blockchain design benefits more from larger network than a small fixed sized one.
venkat
2016-06-28 10:16
Still the question of why should a peer connect to every other peer is not answered
simon
2016-06-28 10:16
because that's how PBFT works
venkat
2016-06-28 10:17
Ah ...
venkat
2016-06-28 10:18
But it could pose limitation on the size of network, then
simon
2016-06-28 10:18
it will, yes
venkat
2016-06-28 10:19
what is th max size?
simon
2016-06-28 10:19
for every block, every node needs to send and receive 2N messages
simon
2016-06-28 10:19
we don't know what a realistic upper bound is
simon
2016-06-28 10:20
it depends on your interconnect
simon
2016-06-28 10:20
and the size of your batches
simon
2016-06-28 10:20
i.e. the frequency
karthik
2016-06-28 10:21
@simon: is it for every transaction every node send and receive 2N messages or is it for every block?
simon
2016-06-28 10:21
i said block
venkat
2016-06-28 10:22
So it is 2*N*N messages per block?
venkat
2016-06-28 10:23
for all nodes
simon
2016-06-28 10:24
yes
venkat
2016-06-28 10:24
2 = one receive and one send, i guess
simon
2016-06-28 10:24
no, the protocol is two rounds
venkat
2016-06-28 10:24
or confirm, may be
simon
2016-06-28 10:24
you receive 2 and send 2
venkat
2016-06-28 10:24
Got it
simon
2016-06-28 10:24
i guess currently it is receive 3 and send 2
venkat
2016-06-28 10:25
oh
venkat
2016-06-28 10:30
So it is 2 rounds, and in each round we have 2+3 = 5 messages (10 msgs total). Did I bloat up the numbers ?:slightly_smiling_face:
venkat
2016-06-28 10:31
Guess - I need t read more on PBFT
simon
2016-06-28 10:33
yes you did
venkat
2016-06-28 10:37
Let me try again. for every block, every node sends 2N messages and receives 3N messages. Is that about right?
simon
2016-06-28 10:40
yes
simon
2016-06-28 10:40
well, one node needs to send another N messages
buhrmi
2016-06-28 10:40
math is hard
simon
2016-06-28 10:40
or it doesn't add up
simon
2016-06-28 10:41
but really, N is the important part
simon
2016-06-28 10:41
not the small integer multiplier
buhrmi
2016-06-28 10:42
is there any consensus algorithm that has been developed for a dynamic network of large number of Nodes
buhrmi
2016-06-28 10:43
the ones i've found assume a fixed sized network where every node is known to all other nodes
simon
2016-06-28 10:46
well there is stellar and ripple
buhrmi
2016-06-28 10:48
right ... maybe port that one to hyperledger
simon
2016-06-28 10:49
go ahead
buhrmi
2016-06-28 10:49
but ...
simon
2016-06-28 10:49
but?
buhrmi
2016-06-28 10:50
afaik they also depend on a set of nodes defined in the config file for consensus
simon
2016-06-28 10:51
so?
buhrmi

buhrmi
2016-06-28 11:52
without central authority
buhrmi
2016-06-28 11:52
or certificate authority
simon
2016-06-28 11:53
i think you need to think about some fundamental properties and guarantees then
buhrmi
2016-06-28 11:53
yeah...
simon
2016-06-28 11:53
did you read satoshi's paper?

simon
2016-06-28 12:17
did you understand it?
buhrmi
2016-06-28 12:17
yeah well its just the bitcoin blockchain explained
buhrmi
2016-06-28 12:18
im thinking that instead of using proof-of-work to decide which transactions go into a block, maybe we can implement Raft
buhrmi
2016-06-28 12:19
but i don't know if thats efficient for a large number of nodes
buhrmi
2016-06-28 12:20
or stellar consensus protocol
buhrmi
2016-06-28 12:21
might be the way to go after all
simon
2016-06-28 12:21
did you understand incentivation?

buhrmi
2016-06-28 12:26
@jamie.steiner: woah brainfreeze
simon
2016-06-28 12:28
my point is that unless you understand incentivation and possibly game theory, whatever you build most likely will quickly be exploited for things you don't want
buhrmi
2016-06-28 12:31
i understand
simon
2016-06-28 12:32
so if you want an open ledger, you need to work on incentivation
buhrmi
2016-06-28 12:32
unless exploitation is part of the game
simon
2016-06-28 12:33
what do you mean by that?
buhrmi
2016-06-28 12:34
i mean that it might be fun building a system and then watch people exploiting it
buhrmi
2016-06-28 12:34
and then punch them in the face
simon
2016-06-28 12:34
i can't take you seriously
buhrmi

buhrmi
2016-06-28 13:01
im not good with Golang, tho
ibmdannywong
2016-06-28 13:14
@simon: following the discussion between you and @venkat about the no. of message to send, i would like to clarify...
I saw this statement,
For every block, every node sends 2N messages and receives 3N messages.
Then I saw this afterward
well, one node needs to send another N messages
So, in total, it is 3N messages sent and 3N messages received?
ibmdannywong
2016-06-28 13:15
where N = No. of Validating Nodes
simon
2016-06-28 13:15
no, i was wrong
simon
2016-06-28 13:15
so what happens is that first a request is broadcast (receive_count=1)
simon
2016-06-28 13:16
the primary then broadcasts a pre-prepare (receive_count=2)
simon
2016-06-28 13:16
then all replicas other than the primary broadcast a prepare (receive_count=2+N-1-1=N)
simon
2016-06-28 13:16
then all replicas broadcast a commit (receive_count=2N-1)
simon
2016-06-28 13:17
likewise, all replicas send 2N-2 messages, except for the originator, which sends 3N-3 messages
ibmdannywong
2016-06-28 13:20
Yes, right.
ibmdannywong
2016-06-28 13:20
Take me some minutes to think over your illustrations..
simon
2016-06-28 13:20
with batch it is a bit different, but close enough
ibmdannywong
2016-06-28 13:23
primary = originator?
ibmdannywong
2016-06-28 13:24
sorry for being a n00b...
simon
2016-06-28 13:27
no

Thanks Simon
ibmdannywong
2016-06-28 13:31
it clarifies a lot!
buhrmi
2016-06-28 13:35
is primary something like the leader?
simon
2016-06-28 13:36
what leader
ashnur
2016-06-28 13:37
@simon: like Paxos has a leader, I am guessing
simon
2016-06-28 13:38
sure
ibmdannywong
2016-06-28 13:38
https://github.com/hyperledger/fabric/blob/master/docs/protocol-spec.md#fabric
The Sieve protocol uses core PBFT to agree on whether to accept or discard a request. Execution of requests to Sieve is coordinated by a leader, which maps to the current PBFT primary (leveraging innerCPI.viewchange notification from core PBFT) . Upon a new request, the leader will instruct all replicas to tentatively execute the request.
jamie.steiner
2016-06-28 13:52
Is the output/result of request execution subject to consensus prior to final commitment into the blockchain/ledger/database?
simon
2016-06-28 13:53
no
simon
2016-06-28 13:53
not at the moment
middleton
2016-06-28 13:53
I believe PBFT is order N^2 messages.
simon
2016-06-28 13:54
middleton: yes, if every node sends order N messages, overall it is order N^2
jamie.steiner
2016-06-28 13:54
do you believe consensus on results is required?
simon
2016-06-28 13:55
yes
simon
2016-06-28 13:55
especially with languages like go
simon
2016-06-28 13:56
for the chaincode, i mean
jamie.steiner
2016-06-28 13:57
it seems like it would be required to me also, though I'm not sure I understand why it would have much to do with the choice of languages.
simon
2016-06-28 13:58
well if you have a deterministic language, then the result is the same everywhere
jamie.steiner
2016-06-28 13:59
sure, but a byzantine node could execute some other code. The result, or at least the final state of the ledger should be agreed upon in a BFT manner before final committment.
simon
2016-06-28 14:00
pbft can tolerate a byzantine node
simon
2016-06-28 14:00
so it doesn't matter
middleton
2016-06-28 14:01
PBFT can handle a byzantine node in a "practical" way. :wink:
jamie.steiner
2016-06-28 14:03
perhaps I am missing something. I thought I understood the process thusly:
1) chaincode is invoked
2) the invocation is subject to consensus, if it is agreed,
3) the nodes execute the code that was called, producing some results which get committed
my point was that it seems necessary to have a 4th step - the results (or at least the final state of the ledger, resulting from all transactions) are subject to consensus, before commitment
jamie.steiner
2016-06-28 14:06
although, I suppose, if a byzantine node executes some other code, and ends up with a different new ledger state as a result, this will prevent it from being part of the next round of consensus. or at least it does not provide a way to impose it's incorrect state on other nodes

yacovm

otherwise it's the fully qualified config name in uppercase
cloud.strife
2016-06-28 14:11
I set `NetworkMode: hlnet` in core.yaml. but the hyperledger ignores this and creates the conatiners in the default host network mode

hlnet is the name of the overlay network I created

@buhrmi - the consensus mechanism for # allows for large validator populations
kelly
2016-06-28 15:37
it also allows for dynamic membership
kelly
2016-06-28 15:37
it is very similar to nakamoto/dmms consensus, but it requires a intel processor with SGX instead of a mining chip
buhrmi

@kelly: @buhrmi - trusted execution environment is great when you want to be sure your machine is working as you want. It's not so good when you want to prove to a third party that your machine is working as they expect.
kelly
2016-06-28 17:14
@jamie.steiner: if you trust the hardware, things like intel SGX allow for remote attestation
kelly
2016-06-28 17:15
the TEE can generate a certificate that details which computation it ran, and the output
kelly
2016-06-28 17:16
it is signed by the TEE with a hardware based key that _theoretically_ can't be extracted
jamie.steiner
2016-06-28 17:28
if you believe the hardware implementation is secure, you still have a PKI web of trust model for key security. I guess that's the theoretical part

@kostas: i think the difficulty with stellar is that your network has to have the property of quorum intersection despite all your ill behaved nodes ... not sure how you practically guarantee that (without devolving into something not far removed from PBFT). If you want to dig a bit deeper into the stellar white paper, i found this to be a useful overview: https://www.youtube.com/watch?v=vmwnhZmEZjc

How much traction has hyperledger gotten?
kelly
2016-06-28 21:56
as measured by?
shadedjon
2016-06-28 21:57
is it understood how it's going to work?
shadedjon
2016-06-28 21:58
I guess I just don't understand the point of it?

i hope it can become "the great ledger" where everybody can submit transactions to without a central authority or root certificate
buhrmi
2016-06-29 02:58
but before that happens, there needs to be a better consensus implementation and the chaincodes should be run in some kind of VM so that they can't take down an entire host system lol
danayelx
2016-06-29 03:00
do you guys have a source to that story?
danayelx
2016-06-29 03:00
i would like to see how it happened
danayelx
2016-06-29 03:00
and replicate the scenario
buhrmi
2016-06-29 03:09
no i just made this up
ibmdannywong
2016-06-29 03:20
From my understanding, the chaincode is executed in a secured container in bluemix, it provides certain level of isolation
buhrmi
2016-06-29 03:21
anyone here who has worked on chaincode isolation and can shed some light on it? what works, what doesnt... with golang
buhrmi
2016-06-29 03:22
obviously we can't all pay for bluemix if we wanna run a node (even though IBM would probably like that)
danayelx
2016-06-29 03:24
you can just spin off your own network
danayelx
2016-06-29 03:24
download the code and test it
danayelx
2016-06-29 03:24
everything is executed within containers
danayelx
2016-06-29 03:24
isolated
bgorman

@buhrmi I'm having a play around with hyperledger now and it looks like each chaincode gets run in its own Docker container
bgorman
2016-06-29 03:28
each of my (4) peers seem to have a chaincode app container, as well as their own container... for a total of 8 containers

You can check the peer logs and see them spin up the containers.

I'm just running `docker ps -a` and looking at what's there
buhrmi
2016-06-29 05:20
does a new container get created when u deploy another contract?
ashishkel
2016-06-29 05:25
@buhrmi: u meant the docker container rite?
buhrmi
2016-06-29 05:25
yeah
ashishkel
2016-06-29 05:26
that is my understanding also
bgorman
2016-06-29 05:27
yes, the docker container labels are of the format <networkID>-<nodeID>-<chaincodeID>
ashishkel
2016-06-29 05:27
@bgorman: if i understood correctly, u have setup 4 peers, and then in each peer u hav deployed one chain code each ?
bgorman
2016-06-29 05:27
so each contract gets its own chaincode ID and it's own container on each network/node
bgorman
2016-06-29 05:28
@ashishkel: I have four peers and I deployed two chaincodes, which were distributed amongst the peers
ashishkel
2016-06-29 05:29
so the other two peer also picked up the same chain code? and created a docker container to execute the same..?
bgorman
2016-06-29 05:29
so 2x4 containers for chain codes, 1x4 containers for the peer hosts and a few other containers for things like fabric-baseimage
bgorman
2016-06-29 05:29
@ashishkel: yes
jamie.steiner
2016-06-29 05:30
wait, so each chaincode *is* deployed in it's own container?
bgorman
2016-06-29 05:30
I could have the peers on other machines, but I'm doing this all in the one vagrant VM
ashishkel
2016-06-29 05:30
@bgorman , same here.. I m also doing in one single vagrant vm
ashishkel
2016-06-29 05:32
@jamie.steiner , thats what I have seen..
bgorman
2016-06-29 05:34
It looks like each chaincode runs in its own VM and is interacted with by its owning peer only through REST calls
ashishkel
2016-06-29 05:35
are u sure about the REST calls?
ashishkel
2016-06-29 05:36
u mean the chaincode <-> peer interaction is thru REST. ? are u sure about this?
bgorman
2016-06-29 05:36
pretty sure
ashishkel
2016-06-29 05:36
cos I read something like the gRPC .. which was a bit different..
ashishkel
2016-06-29 05:36
some messaging protocol used by google on its microservices.. which was more like faster in communicating..
bgorman
2016-06-29 05:37
I think gRPC is between peers
buhrmi
2016-06-29 05:37
so what if there are millions of chaincodes
buhrmi
2016-06-29 05:37
each peer has millions of docker containers?
jamie.steiner
2016-06-29 05:37
exactly
bgorman
2016-06-29 05:38
talks about JSON on /chaincode API -> https://github.com/hyperledger/fabric/blob/master/docs/API/CoreAPI.md#chaincode
bgorman
2016-06-29 05:39
hmm... but this one talks about gRPC -> https://github.com/openblockchain/obc-docs/blob/master/protocol-spec.md
jamie.steiner
2016-06-29 05:42
maybe JSON is client <-> peer and gRPC is peer <-> chaincode?
bgorman
2016-06-29 05:45
could be :slightly_smiling_face:
ashishkel
2016-06-29 05:47
the way i understood is, for a peer to interact with a chaincode, they hv developed a SHIM layer.. which has a set of APIs in go language, nd uses this protocol buffer based Message structure ( proto3 is the standard name)
ashishkel
2016-06-29 05:48
and for any of us, i mean the client apps, to interact with the chaincode, there is this REST interface and CLI interface
ashishkel
2016-06-29 05:49
nd @bgorman , that openblockchain link you have given,
ashishkel
2016-06-29 05:49
that is uptodate?
bgorman
2016-06-29 05:49
I don't know sorry. I'm still trying to get this all straight in my own head :slightly_smiling_face:
ashishkel
2016-06-29 05:50
cos i also heard that those folks merged and formed the hyperledger repo.
ashishkel
2016-06-29 05:50
nd they maintain the latest in this .. https://github.com/hyperledger/fabric/
ashishkel
2016-06-29 05:50
nd the latest protocol spec here.. https://github.com/hyperledger/fabric/blob/master/docs/protocol-spec.md
bgorman
2016-06-29 05:50
that seems true
Notice: This repository has been moved to the Linux Foundation's Hyperledger project.
bgorman
2016-06-29 05:51
cheers, I'll read that one instead
ashishkel
2016-06-29 05:51
nd this current one is buzzing with activity..
ashishkel
2016-06-29 05:51

2016-06-29 06:35
Actually wanted to know about the security features of HL which makes it stand out compared to may be ethereum?
What would be that trump card other than the obvious that HL is a permissioned ledger taking in mind a a huge inflow of transactional data as an inflow to the ledger?

We have just started playing around with hyperledger and have some basic question on deploying chaincode on fabric:
If we have to deploy our own chaincode, does it need to be in public github repo? We looked at stack overflow (http://stackoverflow.com/questions/37433618/how-to-use-a-chaincode-thats-not-on-github) and that answer seem to cover dev scenarios but we are interested in knowing if chaincode can be deployed without having to rebuild the validating peers and/or host the chaincode in public github repo?
danayelx
2016-06-29 22:41
you can push any chaincoide you have
danayelx
2016-06-29 22:41
just need to pass absolute path
danayelx
2016-06-29 22:41
are you running your own instance of hyperledger?
danayelx
2016-06-29 22:41
they have this in the path: http://github.com/hyperledger/fabric/peer/yourfolderwiththecc
danayelx
2016-06-29 22:42
if you follow the tutorial you will realize that http://github.com/hyperledger/fabric/peer/yourfolderwiththecc is a a path on your local machine
danayelx
2016-06-29 22:42
not a path in github
atulkc
2016-06-29 22:47
our validating peer is not running on the same machine where the new chaincode is...would it still be able to pick up the chaincode from the client machine where the chaincode is located (machine that is issuing deploy command)

@atulkc: after the "deploy" command the chaincode actually gets embedded into the blockchain and distributed amongst the peers
danayelx
2016-06-30 01:53
@atulkc: To clarify, per hyperledger’s github page: The IBM Bluemix IBM Blockchain service currently requires that chaincode to be in a GitHub repository. Therefore, if you don't already have a GitHub account, you should get one.
danayelx
2016-06-30 01:54
that means that if you are using bluemix then def need to host your code within github

@venkat: it really depends on the/your definition of serious apps...
jonathanlevi
2016-06-30 20:58
Fabric is still at the `Incubation` stage (see the docs/wiki for definitions)
jonathanlevi
2016-06-30 21:00
There is a dev-preview tag from a few weeks ago, there are issues on various platforms (ongoing development to stabilize the zLinux build, for example) and some of the underlying components are moving relatively rapidly. HOWEVER,
jonathanlevi
2016-06-30 21:06
I believe that you should start developing against/with it, and if it's a serious application that requires loads of testing/trying/scaling, etc... the sooner you start developing, the better. I clearly don't know enough about what you are trying to do, but in general, a PoC/Mockup will give you a much better sense as for its readiness for your specific needs [And will allow you to ask us many more questions! ;-)]. There are a few companies/developers that are doing this these days already... I can tell you this.
atulkc
2016-06-30 21:14
@cbf what are the other means to uploading chaincode to Fabric besides rebuilding the peer binary with the chaincode embedded?

ghaskins
2016-07-01 00:31
@atulkc: to be clear, you do not ever need to rebuild the peer binary to deploy chaincode
atulkc
2016-07-01 00:34
@ghaskins: that was one of the options proposed in stack overflow...however, I am still unclear on how to deploy chaincode that is not on public github repo. Lets say I want to deploy something from private repo. Since deploy codechain uses `go get` I think it is kind of forcing me to have my chaincode in public github repo unless somehow peer gets the creds for private github repo
ghaskins
2016-07-01 00:37
The shortest answer I can offer is to use member.deploy() from the node sdk
ghaskins
2016-07-01 00:38
No peer binary rebuilds, no GitHub necessary
ghaskins
2016-07-01 00:39
I'm not sure what was said on stack overflow but it sounds like misinformation
atulkc
2016-07-01 00:41
thanks @ghaskins it sounds like I need to use node sdk rather than `peer` cli or REST api...i was told about node sdk on #memerbship-services channel as well
ghaskins
2016-07-01 00:42
People (including myself) have been confused about peers, clients, and the rest api. But at no time was it ever necessary to rebuild the peer and the SDK exposes a more obvious path forward (even though both offer the same basic mechanism under the hood)
atulkc
2016-07-01 00:43
i think the stack overflow answer was mentioning it in context of dev setup...where you put the chaincode under `fabric/examples/go/chaincode/` and then rebuild the peer image...
atulkc
2016-07-01 00:44
but that might be just that...dev env only...
atulkc
2016-07-01 00:45
when I tried deploying from private github repo with `peer` cli then deployment failed because `go get` couldn't get the files...once I used public repo it worked....
ghaskins
2016-07-01 00:50
yeah, the confusing thing is that the REST api is only meant to be used as an extension of your client to an NVP
ghaskins
2016-07-01 00:50
if you think of it as an entry point to the network, the way it behaves doesnt make sense
ghaskins
2016-07-01 00:50
to that point, it only makes sense if you have a client+NVP running on the same machine
ghaskins
2016-07-01 00:51
in which case, the deployment that references a local file is logical
ghaskins
2016-07-01 00:51
The SDK collapses the NVP function into your nodejs process, which is more natural
ghaskins
2016-07-01 00:52
but regardless, even with the client+rest+nvp model, you still do not need to rebuild the peer binary
atulkc
2016-07-01 00:55
oh ok, got your point about rebuilding peer binary. i will explore the node sdk further.
jonathanlevi
2016-07-01 01:24
@atulkc: the simplest is probably to use the (public) github for now... btw, I like to view the node/sdk as one 'reference implementation' (potentially, one of many). It might be easier to start at a higher level (without building).
jonathanlevi
2016-07-01 01:25

I have some query on Hyperledger Tables and World state (stub.CreateTable(…), stub.PutState(…))
1) When the table creates, will it create into all other nodes in the network?
2) Is the tables and world state persists in RockDB or any other system file?
3) Will the table or state of the table add to block when any state changes in table columns or only world state will be add to the block?
4) Is the tables part of world state ?

garisingh
2016-07-01 10:37
@g_alexander:
1) Tables are actually created by chaincode. Assuming you do the table creation in the "init()" method of chaincode, then when the chaincode is deployed to all the nodes the tables will be created. If you chose to create the tables at first use the same would hold true. Chaincode execution is what "creates" the tables
2) Yes - RocksDB persists world state. Tables are just a layer created on top of the standard K/V structure of RocksDB
3) Blocks contain transactions and transactions are basically the "instructions" which tell the peer which chaincode / function to execute using the parameters passed in the invoke. A "block" is created after the execution of the transaction(s) (number of transactions per block is configurable) and each block contains a hash of the world state after all of its contained transactions have executed
4) I think 3) above answers this as well

that means hash of the world state contains the table values and the old status of the table row can be taken from the old block ?
simon
2016-07-01 11:59
no
g_alexander
2016-07-01 12:03
u mean the old status of the table row CAN NOT be taken from the old block ?
g_alexander
2016-07-01 12:30
Also as per protocol specification
3.2.1.4 Transaction Execution
When chaincodes execute, they may modify the world state. The hash of the world state is then recorded in the block.
1) If the table rows status also be part of the world state, then table row should be recorded in the block.

b. How it will works for Audit Support?
2) Audit Support is there in current version or is it in the feature enhancement?

I have a question from our potential partner, they ask about crypto algorithms that are used in fabric and if it's possible to 'plug-in' other algorithms.

Why does the environment variable CORE_PEER_ADDRESSAUTODETECT have to be set to true when starting the peer, or else, chaincode handler could not process any messages
bgorman
2016-07-04 05:52
@james.buckett: have you set the peer's address and listenAddress separately? I think they may be related

[btw hi, not spoken to you in ages :slightly_smiling_face: ]

Hi, some documents on GitHub says that a non-validating peer maintains local copy of the ledger. However, by observing the behavior of NVPs, it seems they don’t maintain ledger data. Is it intended, or just a matter of out-dated documents? https://github.com/hyperledger/fabric/blob/03c751fcc72b3a9c89985b1c4c290233a6871995/docs/glossary.md

hey guys I'm testing the car lease demo and I have a question about running queries based on a license number
mart0nix
2016-07-07 12:43
my understanding is that the data storage is a key-value store so my question is how are different events related to a particular license plate stored so that later one can pull up the entire history by quering for a license plate number
ant2221
2016-07-07 13:49
the V5C ID is the key rather than the license
mart0nix
2016-07-07 14:16
@ant2221: I thought you can have only unique keys
mart0nix
2016-07-07 14:16
can you store different values for the same V5C ID ?
ant2221
2016-07-07 14:45
I believe it is the V5C ID that is passed into the Smart Contract which then retrieves the data relating to that V5C

@pards I think it only keeps a hash of the previous states, not the actual values. So to retrieve old values I'm guessing you would have to re-calculate them... either starting from block 0 and working your way forward, or it might be possible to also work your way back from the current state

I also want to know if we can see all the previous values for a particular key.

Otherwise we need to keep the version of values for a particular key in chaincode. That's sure not a good idea.

tables are just a helper with partial key queries. At the end of the day it’s still keys/values. In the next ledger architecture we’re looking to adding more advanced query mechanisms

Hi all! I have two dumb questions, and hope someone knowledgeable can save me from this, which will be really appreciated.
1) can I run multiple peer nodes on local machine via devenv vagrant? (not using docker) — I hit an error (Failed to listen: listen tcp 0.0.0.1:30303: bind: address already in use)
2) if I use docker following this doc(https://github.com/hyperledger/fabric/blob/master/docs/dev-setup/devnet-setup.md), then how can I access to its REST API server? I set up 0.0.0.0:5000 in the core.yml file, but this address isn’t responding from webbrowser & postman.
My goal is deploy a chaincode in my local machine, run multiple nodes in the network, and communicate via REST API to build a webapp...

@yiseul: if you follow devnet-setup.md it is going to end up using docker containers for chaincode and peers. To avoid docker, you need to follow this: https://github.com/hyperledger/fabric/blob/master/docs/API/SandboxSetup.md
bgorman
2016-07-11 01:26
You'll need to configure each peer to listen on a different ports to the other as well
bgorman
2016-07-11 01:27
As for the REST API, try http://localhost:5000/ or http://<hostnameHere>:5000/ - there should be a port forward from your Virtual Box / Vagrant VM set up to forward the port to the hosting machine

how to list the resources available on the ledger, I keep receiving the following error
`Error: Error querying chaincode: rpc error: code = 2 desc = "Error:Failed to launch chaincode spec(Could not get deployment transaction for chaincode-helloworld - LedgerError - ResourceNotFound: ledger: resource not found)"`

How can multiple businesses control the same network running a blockchain? I mean for contributing peer nodes etc, in a consortium context. They will all be using a single blockchain. Currently I don't think we can do this on BlueMix. There is a dropdown for selecting an application though. Not sure what it is for.
venkat
2016-07-11 12:26
In other words - are there any API in Fabric, which allow nodes to download the same blockchain and be connected to peers owned by other businesses?
venkat
2016-07-11 12:34
I guess, the membership services is the key here? But how are the peer nodes bootstrapped with URLs for other peer nodes and blockchain ID etc?
venkat
2016-07-11 12:36
Some off-line enrollment is used?

guys, has anyone tried to use hyperledger in some real use cases? as far as I have understood it is in the early incubator stage and not production ready, right?
ashnur
2016-07-11 13:36
imho none of the current blockchain technologies are in production ready state yet
roman
2016-07-11 14:12
well, bitcoin and etherium is kind of there. I may rephrase to avoid that kind of discussion. My understanding is that hyperledger is far from being ready even for beta testing, right?
ashnur
2016-07-11 14:35
Hmm, harder question. I find it quite easy to experiment with it and a lot of features are already there.

hey guys, so i have two nodes running and trying to deploy chaincode, however, only way i have been able to do so is by adding my code to github and deploying from there
danayelx
2016-07-11 16:58
the code is in both the vm path and my local machine path
danayelx
2016-07-11 16:58
for some reason even if i use absolute path (both vm or local host) or even relative paths, it wont launch
danayelx
2016-07-11 16:59
what am i doing wrong? btw, running local nodes, not bluemix
codascud
2016-07-11 17:29
@danayelx: I have tried deploying contracts from within $GOPATH and it works.. Are the absolute paths you are using in GOPATH?
danayelx
2016-07-11 18:06
yes, which is weird
codascud
2016-07-11 18:07
can you paste the command that you use to deploy the CC?

2016-07-11 18:08

2016-07-11 18:09
from within /opt/gopath/src/github.com/hyperledger/fabric/peer
danayelx
2016-07-11 18:09
I call
danayelx
2016-07-11 18:09
CORE_PEER_ADDRESS=172.17.0.2:30303 ./peer chaincode deploy -p https://github.com/danayelx/chaincode/finished -c '{"Function":"init", "Args": ["hi there"]}'
danayelx
2016-07-11 18:10
that works well, but if I do $GOPATH/path/to/chaincode it won’t work
danayelx
2016-07-11 18:10
even if I do absolute path
harsh
2016-07-11 18:10
correct me "CORE_PEER_ADDRESS=172.17.0.2:30303 ./peer chaincode deploy -p $GOPATH/path/to/CC/ -c
harsh
2016-07-11 18:10
should work
danayelx
2016-07-11 18:11
yeah won’t work, perhaps something is misconfigued on my system
harsh
2016-07-11 18:11

danayelx
2016-07-11 18:11
if you guys can do it, then it is my config
codascud
2016-07-11 18:15
@danayelx: Is your chain code under $GOPATH/src/path/to/chaincode ?
danayelx
2016-07-11 18:15
yes
danayelx
2016-07-11 18:17
well, I will keep experimenting. My setup is at home so can’t debug now :slightly_smiling_face:

We running a use case like, deploy, invoke( insert some data into table), into one peer (172.17.0.2) then query the table data from another peer (172.19.0.3). but we are not able to get the value and it throwing the error like "Error: Error querying chaincode: rpc error: code = 2 desc = "Error:Failed to launch chaincode spec(Failed to init chaincode(handler not found for chaincode usecase))". it is not working for both security is turned off/on.

what is the error u are getting on the console when u deploy?

when we enable the security , then we are getting "[ledger] sendProducerBlockEvent -> ERRO 702 Error unmarshalling deployment transaction for block event: proto: protos.ChaincodeDeploymentSpec: wiretype end group for non-group" while deploying the chain code. there no error of security off mode

I think the Docker images have the chain code baked in

does anyone know if there is a limit in terms of how much we can store in the state?
danayelx
2016-07-12 16:41
since its nothing but a key value store
danayelx
2016-07-12 16:41
i wonder how much content we can store on it
danayelx
2016-07-12 16:42
also, another question. Each invokation is recorded on the blockchain right? ideally. So we can track everyting that is stored there? If so, how do we decode the tx information. For bitcoin there are plenty of utilities that decode tx hashes/serialized content. Are there such utilities for hyperledger?
danayelx
2016-07-12 16:43
like I can use a tx hash to fetch its contents and deserialize them
danayelx
2016-07-12 16:43
in the bitcoin client, not sure if that is doable with hyperledger
pards
2016-07-12 17:03
I think it uses RocksDB for the key-value store
pards
2016-07-12 17:04
I haven't figured out how to decode the TX payload yet.
pards
2016-07-12 17:04
If you do, please post it here
pards
2016-07-12 17:05
bgorman didn't seem to think it was possible
danayelx
2016-07-12 17:31
mmm, interesting. It would be nice to be able to decode txs
danayelx
2016-07-12 17:31
right I know it uses rocks db
danayelx
2016-07-12 17:32
but when you do a write, say using chaincode, is there limit in terms on how much data you persist?
pards
2016-07-12 17:33
RocksDB doesn't seem to have a real limit, but there may be one in Fabric
cbf
2016-07-12 17:34
the storage is limited by the physical constraints… there is currently some thought being given to pruning a blockchain (think of archiving from the active database to some other store, ala glacier
danayelx
2016-07-12 17:35
yeah rocks doesnt but does the fabric limit chaincode from storing too much
danayelx
2016-07-12 17:35
well like @cbf said, physical limits
danayelx
2016-07-12 17:36
mmm, ill look into the decoding part and share anything i find
danayelx
2016-07-12 17:37
that is a really useful thing, the python tools i used to decode bitcoin tx were a life saver, something like that would be very useful here too imo
pards
2016-07-12 17:37
I agree.
pards
2016-07-12 17:37

https://bobsummerwill.com/2016/07/12/ethereum-everywhere/
TL;DR – What are you proposing?
I am proposing to the contributors that the C++ Ethereum client runtime cpp-ethereum be re-licensed from the copyleft GPLv3 license to the more permissive Apache 2.0 license, to enable Ethereum software to be used as broadly as possible - a long-standing plan. This proposal only addresses the client runtime and does not include Solidity or Mix (the C++ tools).
There is another blog post detailing the likely operational steps in that process. This document seeks to explain why I am making that proposal.
https://bobsummerwill.com/2016/07/12/c-re-licensing-plan/
I would personally love to see Ethereum as part of the Hyperledger story, and I know that many others feel the same way. Hopefully this re-licensing can be the first step in the journey leading to that outcome.
See also https://bobsummerwill.com/2016/06/12/cats-and-dogs-can-be-friends/.
Best wishes to you all!

Hi Guys any way we can upload files via chaincode into blockchain
\
like in ethereum we have IPFS and Swarm
simon
2016-07-13 10:48
pranob: you'll have to write a chaincode to do that
pranob
2016-07-13 10:50
@simon: thanks! but how do i store file in a blockchain , do we have any API available in hyperledger
simon
2016-07-13 10:50
i suggest reading the chaincode documentation
pranob
2016-07-13 10:50
or we convert it to bytes and then just store
simon
2016-07-13 10:54
what else?
pranob
2016-07-13 10:55
Thanks @simon
muralisr
2016-07-13 11:33
@pranob: an approach could be to store hash of the file in the ledger

rocksdb supports key/value pairs
danayelx
2016-07-13 17:01
the hash should suffice

Hi, I am trying to understand what I need to get prepared for the July Hackathon. The guys from my company who will participate (me included) have no experience with it. I would like to make sure that everyone is prepared with the tools / code etc… Is there something like this being prepared ? What is expected for the hackathon?

Hi everyone, I have submitted a Hyperledger Improvement proposal to TSC, to be discussed in the meeting tomorrow. The proposal is currently on the Wiki page. https://github.com/hyperledger/hyperledger/wiki/Proposals Would love any feedback. I have a quick demo on my github that you can check out. https://github.com/konradpabjan/fabric/tree/master/peer/Explorer (The video is really fast, had to get in under 25Mb)

@ashishkel thanks... I am thinking a testing (before production perspective)... if we want to really init a state of somethings (say a balance as $100), After running a few tx, the balance becomes $70. However, if we found a bug of a private method in the contract (which called by Invoke)
ibmdannywong
2016-07-14 08:55
after I fix the contract... and redeploy the contract
ibmdannywong
2016-07-14 08:56
if init really called, then the balance will become $100 again /_\....
ibmdannywong
2016-07-14 08:56
:joy: Anyone has idea how to resolve this?...
ibmdannywong
2016-07-14 08:59
we can protect the Init() method from being called Invoke() easily... but not from the deploy flow...

Hello, I myself along with other team members are new to Hyperledger and stuff. Being in initial phase of it, we are trying to setup the development environment for the same on our local machines . We followed the hyperledger fabric documentation on http://github.com. We are facing problems in having first and second validating peers up and running. First peer works fine but for the second peer, it is giving error as "grpc: ClientConn.resetTransport failed to create client transport: connection error: desc = "transport: dial tcp [::1]:50051: getsockopt: connection refused"; Reconnecting to "localhost:50051" . Can anyone help us in getting out of this problem? Thanks!
simon
2016-07-14 11:30
firewall?
abhishekseth
2016-07-14 11:35
@simon what do u mean by firewall over here? Could u plz elaborate?
simon
2016-07-14 11:35
do you have a firewall that prevents connection between the peers
abhishekseth
2016-07-14 11:39
See the problem is that if we run command for second peer without having the attributes for certificates like CORE_PEER_PKI_ECA_PADDR=172.17.0.1:50051 -e CORE_PEER_PKI_TCA_PADDR=172.17.0.1:50051 -e CORE_PEER_PKI_TLSCA_PADDR=172.17.0.1:50051, it runs fine and second peer becomes up. But if i include these attributes, error occurs.
simon
2016-07-14 11:41
okay
simon
2016-07-14 11:41
i don't know
simon
2016-07-14 11:41
the CA stuff is a mystery to me
garisingh
2016-07-14 11:45
@abhishekseth: so you are trying to get multiple peers plus membersrvcs (CA) running on the same machine? I assume you are using Docker for the peers and the CA? And am I correct in assuming you have security enabled?
garisingh
2016-07-14 11:47
and are you also passing `CORE_PEER_PKI_ECA_PADDR=172.17.0.1:50051 -e CORE_PEER_PKI_TCA_PADDR=172.17.0.1:50051 -e CORE_PEER_PKI_TLSCA_PADDR=172.17.0.1:50051` when you start the first peer?
abhishekseth
2016-07-14 11:49
Yes, we are using dockers but no, security is not enabled because command having security enabled does not make peer one up.
abhishekseth
2016-07-14 11:50
and same thing happens for peer 2nd also.
Also, are we supposed to edit something in core.yaml and membersrvc.yaml files?
garisingh
2016-07-14 11:51
did you start a container running membersrvcs ?
garisingh
2016-07-14 11:51
if security is not enabled, you don't need membersrvcs at all
garisingh
2016-07-14 11:52
and the peer should not be trying to communicate with membersrvcs if security enabled=false
abhishekseth
2016-07-14 11:56
the problem is that if the security is not enabled then we will not be able to login/enroll the test user.
So, my problem is how to enable security and get both the peers up and running?
can u plz help on that?
simon
2016-07-14 11:56

did you start member service?
garisingh
2016-07-14 13:12
If so, you can try the following:
1) Create a file called `docker-compose-security-base.yml` and paste the following contents:
```
vpSecurityBase:
extends:
file: compose-defaults.yml
service: vp
environment:
- CORE_SECURITY_ENABLED=true
- CORE_PEER_PKI_ECA_PADDR=membersrvc0:50051
- CORE_PEER_PKI_TCA_PADDR=membersrvc0:50051
- CORE_PEER_PKI_TLSCA_PADDR=membersrvc0:50051
```
garisingh
2016-07-14 13:12
you will also need the `compose-defaults.yml` located in the `fabric/bddtests` folder
dthom

garisingh

2) Create a file called `docker-compose-security-2-peers.yml` and paste the following contents:
```
membersrvc0:
extends:
file: compose-defaults.yml
service: membersrvc
vp0:
extends:
file: docker-compose-security-base.yml
service: vpSecurityBase
environment:
- CORE_PEER_ID=vp0
- CORE_SECURITY_ENROLLID=test_vp0
- CORE_SECURITY_ENROLLSECRET=MwYpmSRjupbT
links:
- membersrvc0
ports:
- 5000:5000
vp1:
extends:
file: docker-compose-security-base.yml
service: vpSecurityBase
environment:
- CORE_PEER_ID=vp1
- CORE_PEER_DISCOVERY_ROOTNODE=vp0:30303
- CORE_SECURITY_ENROLLID=test_vp1
- CORE_SECURITY_ENROLLSECRET=5wgHK9qqYaPy
links:
- membersrvc0
- vp0
```
simon
2016-07-14 13:19
haha, this is ludicrously complicated
garisingh
2016-07-14 13:22
make sure that `compose-defaults.yml , docker-compose-security-base.yml and docker-compose-security-2-peers.yml` are all in the same folder and the run `docker-compose -f docker-compose-security-2-peers.yml up`
garisingh
2016-07-14 13:23
@simon - agreed

2016-07-14 13:23
after this, evreything will be okay in security mode as well?

I'm having the same problem. And my intuition tells me that membership service must be initialized first, am I right?
cbruguera
2016-07-14 13:25
The problem is that documentation doesn't mention that. It suggests to run the first node with such arguments, pointing to a membership service that isn't up yet.
cbruguera
2016-07-14 13:26
First step should be how to run the `membersrvc`, then the nodes :slightly_smiling_face:
cbruguera
2016-07-14 13:32
Now, I'm trying to build the member service, but a lot of "permission denied" comes out.. Any idea?

@abhishekseth: did you have any luck with @garisingh’s suggested compose files? I have been spending some cycles refactoring the documentation and adding some clarity. You might want to try that on for size: https://github.com/christo4ferris/fabric/blob/98f3b6f482f27b1c6d6ac26cf6fb093e14cb988f/docs/index.md - Here’s the link to the ca-setup: https://github.com/christo4ferris/fabric/blob/98f3b6f482f27b1c6d6ac26cf6fb093e14cb988f/docs/Setup/ca-setup.md - granted, that only has one peer node.

yes! That's exactly my problem.
cbruguera
2016-07-14 17:48
Although no errors were shown during the `vagrant up`, only the process seemed to stall, so I had to Ctrl-C, and when I re-tried getting the vagrant up, it said the image is "up to date".
cbruguera
2016-07-14 17:49
I guess that's what's happening.

also, it looks like there's no need to "vagrant destroy" when something goes wrong. `vagrant provision` should fix it (or that's what I hope)
grapebaba
2016-07-15 00:05
no, i asked same question before
grapebaba
2016-07-15 00:08
destroy will better because the provision script not idempotent

cbruguera
2016-07-15 00:09
Well, I've destroyed it many times already, and got impatient while building it up so Ctrl-C'ed...

i start vagrant up 7:15
grapebaba
2016-07-15 02:58
not end till now
grapebaba
2016-07-15 02:58
network is so bad in china
grapebaba
2016-07-15 02:58
:scream:
grapebaba
2016-07-15 03:00
my environment came across a issue no space left
slaxman
2016-07-15 03:01
@grapebaba: me also from china, I am ok with vagrant+virtual box, now I am just set up with centos 7,
slaxman
2016-07-15 03:01
should not be network issue,
grapebaba
2016-07-15 03:01
i really hate rebuild
grapebaba
2016-07-15 03:02
use what script
slaxman
2016-07-15 03:02
no script
grapebaba
2016-07-15 03:03
sorry, i have no idea for that
slaxman
2016-07-15 03:04
vagrant up is ok for me, network is better in the morning

anyone has issues with the rest api?
danayelx
2016-07-15 04:12
for some reason I am unable to get data using /transactions/uuid
danayelx
2016-07-15 04:13
I used the uuid from 04:02:04.861 [devops] invokeOrQuery -> INFO 02e Transaction ID: %v dc3e9a6f-2f1b-423f-80a3-67d8ebb38e22

Question... If my v1 of chain code (contract) is deployed (say there are 3 peers in my business network). Then say I found a bug and fixed it afterward, and I would like to deploy the new chain code.
ibmdannywong
2016-07-15 04:15
I will make one Deploy REST / CLI to deploy the new contract from my VP
ibmdannywong
2016-07-15 04:15
will the new contract requires deployment by other 2 VPs?
ibmdannywong
2016-07-15 04:15
i.e. my business partner
danayelx
2016-07-15 04:15
should be in the ledger
danayelx
2016-07-15 04:15
you only deploy once
danayelx
2016-07-15 04:16
they need to know how to invoke it tho
ibmdannywong
2016-07-15 04:16
Yes, assume they know as we are business partner
danayelx
2016-07-15 04:16
they just need hash of new chaincode
ibmdannywong
2016-07-15 04:16
ic, so the new contract (i.e. Deploy, not invoke) will be replicated similar to Invoke Transaction to other peers
danayelx
2016-07-15 04:16
yes
ibmdannywong
2016-07-15 04:16
ok
ibmdannywong
2016-07-15 04:17
damn, i thought we need to coordinate all business partner and schedule a downtime
ibmdannywong
2016-07-15 04:17
lol
danayelx
2016-07-15 04:17
no
danayelx
2016-07-15 04:17
haha
danayelx
2016-07-15 04:17
that’s the whole point
ibmdannywong
2016-07-15 04:18
so actually... is there a concept of "revising" a contract (i.e. v0.1 to v0.2)
ibmdannywong
2016-07-15 04:18
or there is only "new" contract
danayelx
2016-07-15 04:18
whenever you deploy its a new entry in the ledger
danayelx
2016-07-15 04:19
no v1, or v2 as far as I know
ibmdannywong
2016-07-15 04:20
e.g. in my git, a contract /x/y/contract_a.go (i.e. this is a v1) then this v1 is executed for several days. And we found a bug in it and fixed it as /x/y/contract_a.go (v2)
ibmdannywong
2016-07-15 04:20
so... the version is just from development perspective
ibmdannywong
2016-07-15 04:21
from perspective of HL, there is only 1 copy / 1 version of contract_a.go
danayelx
2016-07-15 04:22
every contract will generate a new hash
danayelx
2016-07-15 04:22
when you invoke you will pass the hash of the contract
ibmdannywong
2016-07-15 04:22
right...
danayelx
2016-07-15 04:22
so v1 hash will be different from v2
ibmdannywong
2016-07-15 04:23
ok, so... that v1,v2 in git are just from source management perspective
danayelx
2016-07-15 04:23
yes
ibmdannywong
2016-07-15 04:23
ic
ibmdannywong
2016-07-15 04:23
ok
ibmdannywong
2016-07-15 04:23
thanks
danayelx
2016-07-15 04:23
sure n[
danayelx
2016-07-15 04:23
np
ibmdannywong
2016-07-15 04:23
any area puzzling me is that the init method
ibmdannywong
2016-07-15 04:24
if we PutState("my balance", 100) in init method
ibmdannywong
2016-07-15 04:24
then we deploy a new contract (say after bugfix)
ibmdannywong
2016-07-15 04:25
then my balance will be overwritten by the deploy instruction
ibmdannywong
2016-07-15 04:25
of course, we need to design our code
ibmdannywong
2016-07-15 04:25
but just the usage of init is very dangerous..
danayelx
2016-07-15 04:25
I am not sure, but the balance will be defined by the chaincode
danayelx
2016-07-15 04:25
so deploying a new contract may have a new state
danayelx
2016-07-15 04:26
that is a good question
danayelx
2016-07-15 04:26
the state is nothing but a kvs
ibmdannywong
2016-07-15 04:26
yes...
danayelx
2016-07-15 04:26
that you can manage through the given chaincode
danayelx
2016-07-15 04:26
v1 and v2 do not share states
danayelx
2016-07-15 04:26
at least, that is my understanding, someone here please correct me
ibmdannywong
2016-07-15 04:27
umm... v1 and v2 do not share states.. it can be translated into 2 contracts (with 2 hashes) on same ledger (business network )do not share states, right?...
danayelx
2016-07-15 04:29
that is a good q, I am not 100% sure how that would work tbh
danayelx
2016-07-15 04:29
one countract could indeed invoke the other
danayelx
2016-07-15 04:29
and alter the other’s state
ibmdannywong
2016-07-15 04:30
btw, nice profile pic.
danayelx
2016-07-15 04:30
haha, yes, its a classic :slightly_smiling_face:
ibmdannywong
2016-07-15 04:30
love it :stuck_out_tongue:
bgorman
2016-07-15 05:37
@ibmdannywong @danayelx I think a good way to migrate from chaincode v1 to v2 might be to have your v2 Init() query the v1 for its current state and save it as its own
bgorman
2016-07-15 05:38
there's a RangeQueryState() function that you would just walk the whole table with, otherwise you might have the v1 state changing underneath you as you try to populate v2's state
danayelx
2016-07-15 05:46
anyone knows a good way to reset the ledger?
danayelx
2016-07-15 05:47
after a few invocations I keep getting a corrupted ledger
danayelx

I think you can delete /var/hyperledger/production
danayelx
2016-07-15 05:48
taht dir is empty
danayelx
2016-07-15 05:48
that is what I thought too
danayelx
2016-07-15 05:48
but that dir is empty
danayelx
2016-07-15 05:48
what is weird is that on my other setup it is not empty
danayelx
2016-07-15 05:48
i thought rocksdb lived there
bgorman
2016-07-15 05:48
ok... that's where the db is stored.... so that's not good
bgorman
2016-07-15 05:48
yes
danayelx
2016-07-15 05:48
hahah
bgorman
2016-07-15 05:48
you're inside the peer's docker container right?
danayelx
2016-07-15 05:49
yes
danayelx
2016-07-15 05:49
vagrant ssh
danayelx
2016-07-15 05:49
loged in
danayelx
2016-07-15 05:49
launched two instances
danayelx
2016-07-15 05:49
so have 2 node network
danayelx
2016-07-15 05:49
can deploy and query code
bgorman
2016-07-15 05:49
you're on the vagrant machine?
danayelx
2016-07-15 05:49
yes
bgorman
2016-07-15 05:49
not inside docker?
bgorman
2016-07-15 05:49
run `docker ps -a`

your peers are sharp_tesla and amazing_albattani
bgorman
2016-07-15 05:51
maybe determined_sinoussi too
bgorman
2016-07-15 05:51
try `docker exec -it NAME bash`
bgorman
2016-07-15 05:51
that'll get you inside their containers
danayelx
2016-07-15 05:52
yeah one of them has a db
danayelx
2016-07-15 05:52
wait ok, so I thought I had an isolated network
danayelx
2016-07-15 05:53
with bitcoin I can run regtest local
bgorman
2016-07-15 05:53
sorry, I'm not familiar with bitcoin so `regtest local` doesn't mean much to me
danayelx
2016-07-15 05:53
sorry, regtest was the test network
danayelx
2016-07-15 05:53
isolated
danayelx
2016-07-15 05:53
so I could run my own peers
danayelx
2016-07-15 05:54
in like a test env
danayelx
2016-07-15 05:54
with hyperledger, when I start my peer, does it connect to other peers?
bgorman
2016-07-15 05:54
only if you tell it about the other peers
danayelx
2016-07-15 05:54
mmm intereting
bgorman
2016-07-15 05:56
you start a root peer, then subsequent peers need to be told who to talk to about joining the network with CORE_PEER_DISCOVERY_ROOTNODE=172.17.0.x:30303 (or equivalent YAML setting)
danayelx
2016-07-15 05:56
right
danayelx
2016-07-15 05:56
so I have 1 root and one peer I told to join
danayelx
2016-07-15 05:56
where do the others come from?
danayelx
2016-07-15 05:57
or are they just random nodes added to the network?
bgorman
2016-07-15 05:58
first, check what peers are in your network... you can do a GET /network/peers
danayelx
2016-07-15 05:58
{"peers":[{"ID":{"name":"vp1"},"address":"0.0.0.0:30303","type":1},{"ID":{"name":"vp0"},"address":"172.17.0.2:30303","type":1}]}
danayelx
2016-07-15 05:58
only the two I know
danayelx
2016-07-15 05:59
ohhh
danayelx
2016-07-15 05:59
wait
danayelx
2016-07-15 05:59
I see
bgorman
2016-07-15 05:59
well, you've got the peer network you expect then
danayelx
2016-07-15 05:59
the names are random
bgorman
2016-07-15 05:59
yeah, that's a docker thing
bgorman
2016-07-15 05:59
it gives you a "nice" name if you don't assign one
danayelx
2016-07-15 05:59
got it
danayelx
2016-07-15 05:59
thanks
bgorman
2016-07-15 06:00
you can set a name using CORE_PEER_ID=vpX
bgorman
2016-07-15 06:00
when you run peer node start
danayelx
2016-07-15 06:00
got it
danayelx
2016-07-15 06:01
in this case I see I have several docker instances running
bgorman
2016-07-15 06:01
I've started doing that with mine, and got rid of the `--rm` that deletes them when you ctrl+C
danayelx
2016-07-15 06:01
besides the two I just started
bgorman
2016-07-15 06:01
yeah... some will be chaincode instances
danayelx
2016-07-15 06:01
ohhhh
danayelx
2016-07-15 06:01
right
danayelx
2016-07-15 06:01
i forgot about that
danayelx
2016-07-15 06:01
chaincode runs in its own
danayelx
2016-07-15 06:02
is this all written somehwere?
danayelx
2016-07-15 06:02
haha
bgorman
2016-07-15 06:02
you do look like you have 3 peers running though
bgorman
2016-07-15 06:02
not that I've found :slightly_smiling_face:
danayelx
2016-07-15 06:02
yes, I think so too
danayelx
2016-07-15 06:06
awesome thanks!
danayelx
2016-07-15 06:06
im new to devops so still trying to understand all the moving pieces
bgorman
2016-07-15 06:07
found the rocks DB? :slightly_smiling_face:
bgorman
2016-07-15 06:08
nps, the way all this gets deployed (at least in a dev env) is quite new to me too
danayelx
2016-07-15 06:10
yes fond it
danayelx
2016-07-15 06:10
since it is two instances will need to delete both
danayelx
2016-07-15 06:10
that should reset them right?
danayelx
2016-07-15 06:10
is there something more graceful?
bgorman
2016-07-15 06:11
Sounds like it should to me. I'm not aware of anything else, sorry.
bgorman
2016-07-15 06:12
I don't think resetting the ledger is going to be a very common use case :slightly_smiling_face:
danayelx
2016-07-15 06:13
well it is
danayelx
2016-07-15 06:13
here is the problem I am seeing
danayelx
2016-07-15 06:13
I use the default finished chaincode in the tutorial
danayelx
2016-07-15 06:13
I deploy it and write to it
danayelx
2016-07-15 06:14
CORE_PEER_ADDRESS=172.17.0.2:30303 peer chaincode invoke -n $NAME -c '{"Function": "write", "Args": ["key1", "value1"]}'
danayelx
2016-07-15 06:14
that works ok...
danayelx
2016-07-15 06:14
do thsi for a few times

can you link me the tutorial you are using please?
danayelx
2016-07-15 06:16
it still breaks things tho
danayelx
2016-07-15 06:17
the invoke should cause some sort of error

2016-07-15 06:18
instead after that happens, getting transactions through rest does not worl

danayelx
2016-07-15 06:18
that works if invoke does not get called
bgorman
2016-07-15 06:19
looking at the Invoke() in that tutorial, it shouldn't do anything unless the `Function:init` or `write`
bgorman
2016-07-15 06:20
you should have got an error `"invoke did not find func: " + function`
bgorman

bgorman

I've seen Transaction IDs get logged when doing queries, but they don't actually make blocks or transactions

that only happens when a successful PutState() happens (ie. a good Init() or Invoke())

ok, good
danayelx
2016-07-15 06:23
i think you are right
bgorman
2016-07-15 06:23
you could walk your blockchain to confirm that (or just check the chain length afterwards)
danayelx
2016-07-15 06:24
I tried using the logger utility to walk it

I only watched the short video for the explorer, didn't try to use it. Might be buggy?
danayelx
2016-07-15 06:28
possibly, the corrupted tx is at block 6 and it is the only one with an issue

yes
danayelx
2016-07-15 06:32
the thing is that both fabricLogger and possibly the explorer key off the ‘transaction’ key

should it be added?

@bgorman The erorr you got:

Means your chaincode has a compile error so it can't deploy it. Go to your chaincode file and do a go build file.go
Fix any of your compile errors/warnings and then try deploying again.

what is the status of "private" validation on HL. by that I mean validation only using parties to a contract as the data needed to validate may be private. I am assuming that this hasnt as yet been implemented in the consensus system. is that right ?, that it's currently left to the user or wait, we all know we are going to need to do this ?. I also need this network to be dynamic, i need to add and remove parties mid-flight as long as we all agree.

Hello All I am getting an error : panic: Invalid PBFT mode: classic since today when launching hyperledger images
james.buckett
2016-07-17 07:02
has a new image been released that depreciates PBFT mode: classic
james.buckett
2016-07-17 07:20
ok so it looks like classic is depreciated and have to use "batch" with hyperledger images

as Bob Summerwill notes in comments, Hyperledger Fabric is not about public blockchains. It is designed for permissioned blockchain networks "where everyone knows your name”, as it were.

You all know this https://blog.ethereum.org/2016/01/15/privacy-on-the-blockchain/ . The only realistic way of doing this is by only using the nodes on the contract. What I am asking is, is this business of just using the nodes on the contract, and ALL those nodes (everyone has to agree) practice or theory right now with hyperledger ? I have a working solution, but f I can find a standard platform that does this then I dont have to implement my own blockchain from the bottom up, which is in effect what I am doing right now. Proof of work as mentioned above is another one as we appear to be in the hands of the application programmers in the fintech world not to leather the system to death and behave in a socially acceptable manner. My experience of the insurance biz so far doesnt bode well on that front, but if we can restrict the traffic so you only screw your own business partners' systems then it could work.

Guys any one knows which file has been used to configure the vagrant env's IP address?
ashishkel
2016-07-18 06:48
the one which is being used by the fabric of HL
bgorman
2016-07-18 06:53
@ashishkel: you want to change the IP address of the vagrant VM? or you just want to set the IP of the fabric when starting a peer?
ashishkel
2016-07-18 06:53
yea, i want to change the ip address of the vagrant..
ashishkel
2016-07-18 06:53
i see that it always 172.17.0.1
bgorman
2016-07-18 06:54
ok... that's the docker0 interface
ashishkel
2016-07-18 06:54
oh,
ashishkel
2016-07-18 06:54
thats is the docker's ip addres..
ashishkel
2016-07-18 06:54
?
ashishkel
2016-07-18 06:54
ohkay.

Not a docker expert, but I guess something in here may help: https://docs.docker.com/v1.8/articles/networking/
ashnur
2016-07-18 07:50
when using `peer chaincode deploy` how are the path and/or name parameters resolved?
bgorman
2016-07-18 07:58
@ashnur if you mean the chaincode paths, they're on disk in $GOPATH/src for the VM and docker containers
bgorman
2016-07-18 07:59
the names you're referring to might be the docker container names (listed in `docker ps -a`)
ashnur
2016-07-18 07:59
bgorman: no, i don't mean the chaincode paths, i mean the peer chaincode deploy command
ashnur
2016-07-18 07:59
i want to deploy chaincode that is not in $GOPATH/src right now
ashnur
2016-07-18 07:59
because it is not even on the validating peer
ashnur
2016-07-18 08:00
i don't even understand how you can read that question and think about me asking "where are the chaincodes?"
bgorman
2016-07-18 08:01
sorry, I'm not sure what "path and/or name parameters" you are talking about then
bgorman
2016-07-18 08:01
perhaps you could provide an example
ashnur
2016-07-18 08:02
you can give either a path or a name parameter for the peer chaincode deploy command
bgorman
2016-07-18 08:02
as my deploy commands look like `peer chaincode deploy -p <chaincodePath> -c '<args>'
ashnur
2016-07-18 08:02
yeah, you are using path
ashnur
2016-07-18 08:03
but you could be using name
ashnur
2016-07-18 08:03
my question refers to the internal part of this: what kind of paths are allowed there, how they are resolved
ashnur
2016-07-18 08:03
what are my options when passing a path
ashnur
2016-07-18 08:05
all the examples assume that i only ever want to run the examples that are given with the fabric repo, i feel like when I was learning trigonometry and i only had to work on easy triangles with easy angles. when I tried a random triangle with random angles I was confused what should I do
bgorman
2016-07-18 08:06
I think you either have to load the files onto your peer, or I think it also can fetch them from a URL (like a github repo)
bgorman
2016-07-18 08:07
the name part is for this type of development setup: https://github.com/hyperledger/fabric/blob/master/docs/Setup/Chaincode-setup.md
ashnur
2016-07-18 08:09
Yeah, the name part is probably not what I want because after I asked the question here I read somewhere that the chaincode has to be already deployed to the network with that name in order to be used
ashnur
2016-07-18 08:09
which is weird, because why i want to redeploy
ashnur
2016-07-18 08:09
the more I read the more confused I get, that's why I came here :slightly_smiling_face:
bgorman
2016-07-18 08:13
are you developing the chaincode actively, to test locally?
bgorman
2016-07-18 08:13
if so, you want that tutorial I linked to
ashnur
2016-07-18 08:13
:smile:
ashnur
2016-07-18 08:13
people telling me i want something else that i want
ashnur
2016-07-18 08:14
@bgorman: I appreciate you trying to help, don't take it wrongly, it's just that I simply wanted to know the exact algorithm the -p parameter uses
ashnur
2016-07-18 08:14
nothing more, nothing less
bgorman
2016-07-18 08:15
sure, I think it's either a file path on your peer, or a URL it can use for `go get` or similar
ashnur
2016-07-18 09:49
@bgorman: I think this is what I was looking for https://github.com/hyperledger/fabric/blob/v0.5-developer-preview/core/chaincode/platforms/golang/platform.go#L46

The current code saves changes to the vehicle object - but how does it record a history of the changes/updates during the lifecycle of a vehicle ?
mart0nix
2016-07-18 13:58
I remember seeing a vehicle_log.go chaincode which looked like a log of events recorded in an array but that file no longer exists in the repo

@ibmdannywong: I'm not sure I understand the question but... your code does not need to reside in GitHub, it can be on the peer's disk or it could be at another URL
bgorman
2016-07-19 06:36
if you're using the `--peer-chaincodedev` flag you can even just run a compiled binary
pranob
2016-07-19 08:06
Hi Guys do we have any option of querying everything from table without passing key?
bgorman
2016-07-19 08:09
@pranob are you speaking as a developer or the end-user of a chaincode?
ashnur
2016-07-19 08:13
can someone point me to an explanation, or if they have time explain what is the most defining reason to have separate Query and Invoke?
bgorman
2016-07-19 08:13
@pranob if you're developing a chaincode, you can make Query() take no params and return everything it can with GetTable() and related functions.... if you're just a user, it's up to the chaincode's implementation
ashnur
2016-07-19 08:14
so me, as a developer of chaincode, what should I use them for
bgorman
2016-07-19 08:14
@ashnur Query() does not make a Transaction and cannot change the blockchain ... Invoke() can and does
ashnur
2016-07-19 08:14
@bgorman: thank you

2016-07-19 08:15
you're welcome :slightly_smiling_face:

pranob
2016-07-19 09:26
@bgorman: thanks! i am a chaincode developer, but GetTable function just returns table
pranob
2016-07-19 09:27
and getRow or getRows takes keys as parameter
simon
2016-07-19 09:38
pranob: querying all values is a bad idea
simon
2016-07-19 09:39
pranob: it means that you serialize all chaincode invocations

does anyone know what is the solution for that?
muralisr
2016-07-19 12:34
@s.matthew.english: if you running peer in docker you may want to use the docker instance’s ipaddress instead of 0.0.0.0
s.matthew.english
2016-07-19 12:37
I'm not
s.matthew.english
2016-07-19 12:37
I'm running it with vagrant
s.matthew.english
2016-07-19 12:37
I first set up all this http://hyperledger-fabric.readthedocs.io/en/latest/dev-setup/build/
s.matthew.english
2016-07-19 12:38
finally I got it to the point of 'cd $GOPATH/src/github.com/hyperledger/fabric'
s.matthew.english
2016-07-19 12:38
inside of having ssh-ed into vagrant
s.matthew.english

2016-07-19 13:27
hmm
s.matthew.english
2016-07-19 13:27
and I can look at that on localhost?
s.matthew.english
2016-07-19 13:27
let me give it a try

s.matthew.english

vagrant up
s.matthew.english
2016-07-19 13:28
configure the go env in another window also
muralisr
2016-07-19 13:28
right

2016-07-19 13:28
is there a way in linux to like- split a window
s.matthew.english

that has all the same env stuff as one
s.matthew.english
2016-07-19 13:28
like clone it
muralisr
2016-07-19 13:30
as in two vagrant windows bundled into one physical window ?
muralisr
2016-07-19 13:30
not sure … would be platform specific
muralisr
2016-07-19 13:31
but basically you need to “vagrant ssh” in and work the system
cbruguera
2016-07-19 13:32
Yes, you can just open another console windows, step on `devenv` and make `vagrant ssh`.
cbruguera
2016-07-19 13:32
Or at least that's the way I'm doing it.

2016-07-19 21:00
we are seeing some unexpected behavior when trying out hyperledger fabric...we set up our own network with 3 validating peers (using pbft consensus) and pushed deployed some chaincode and did some invoke/query transactions....then we added another validating peer to the network and queried (using REST endpoint) the newly added peer about the block chain length (`/chain/blocks`) and found that it is always `1`. So when we try to do `query` of already deployed chaincode then it fails saying transaction id not found....we tried with `noops` consensus also and saw the same behavior...are we missing something?
atulkc
2016-07-19 21:01
we waited for more than 5 mins to make sure that it is not a timing issue (the total block chain height was 4 so it shouldn't have taken long for syncing)
tuand
2016-07-19 21:16
@atulkc: you need to have all your peers at startup. fabric does not support dynamic addition of peers
atulkc
2016-07-19 21:18
@tuand: oh...then how do we address the usecase of dynamically adding parties to existing block chain. Our usecase is to let third parties join our block chain by using the nodes from their own data center
atulkc
2016-07-19 21:31
is this (no support for dynamically adding peers) a designed/expected behavior or a bug/missing feature?
tuand
2016-07-19 21:35
it's a missing feature. There's a new architecture being proposed. I would say go through this first https://github.com/hyperledger/fabric/wiki/Next-Consensus-Architecture-Proposal

@axc you need to do that inside each peer's docker container, or if you're using --peer-devenv it would be located on your vagrant VM

Hai All, I have deployed a chain code using a IBM Bluemix services and now I am setting up dev Instance using Vagrant . I am able to bring up the instance and work with the existing examples . now I want to deploy the same chain code that I used in BlueMix so below are the steps I followed
somashekar
2016-07-20 06:21
copy the chain code in examples folder ( in a new folder ) and then called the deploy interaction
CORE_PEER_ADDRESS=172.17.0.2:30303 CORE_SECURITY_ENABLED=true CORE_SECURITY_PRIVACY=true peer chaincode deploy -u jim -p http://github.com/hyperledger/fabric/examples/chaincode/go/singleview -c '{"Function":"init", "Args": ["aak1234"]}'

@somashekar: look in the Makefile and comment out the line

you probably want to check that your chaincode didn't get the import statement removed too

I'm having some issues with inconsistencies of GOPATH during the travis build in between what the docker images are built in and the Travis environment. It seems that when the images are built the GOPATH is /opt/gopath but when the container runs it is /home/travis/gopath which causes some of the new BDD tests I've written to fail.
Is anyone able to help me with this?

After "vagrant halt", how to re-start it properly? I tried three methods: "vagrant up", "vagrant up --provision" and "vagrant up" + "vagrant provision", no error returned. But after I login via "vagrant ssh", the bash prompt shows "root@ubuntu-1404:", no "hyperledger" keyword. In addition, the peer-image and membersrvc-image I built before can't show up correctly --- Their REPOSITORY and TAG are <none>. If I "vagrant destroy" and then "vagrant up", I can login host VM properly, but it's timeconsuming and images need rebuilt. Any suggestion here? Thanks!

Well I had to spend some significant time to make sure the VM was properly provisioned. If `vagrant provision` doesn't fix it, it might be needed to `destroy` and `up` again.

Hello all.. I needed one help regarding creating my own chaincode examples.
I wrote one chaincode in GO and inserted the folder containing it in the directory where other examples are. Now, when I try to deploy this chaincode, it shows the error “path to chaincode does not exist “ which is not the case actually. Any help is appreciated!
bgorman
2016-07-21 05:45
Heya @abhishekseth did you put the .go files on the Vagrant VM or the peer docker containers?
abhishekseth
2016-07-21 05:49
@bgorman how do we check that? I manually put the new folder containing that newly created .go file in the ./examples/chincode/go folder
bgorman
2016-07-21 05:49
I'm guessing you did that on the vagrant VM
bgorman
2016-07-21 05:50
you can run `docker exec -it <container_name> bash` to get into the peers containers
bgorman
2016-07-21 05:51
from there you can add the file
bgorman
2016-07-21 05:51
otherwise I think you could rebuild the peers with `make peer-image` on the vagrant VM... that's is probably going to destroy your existing peers in the process though
bgorman
2016-07-21 05:52
third alternative is to deploy your chaincode from source on http://github.com (or any other website I guess)
abhishekseth
2016-07-21 05:55
adding a new folder at the place where other example folders are, does not suffice?
bgorman
2016-07-21 05:55
the peers have their own file systems, if you add a file to the vagrant VM, the peer will not see it
bgorman
2016-07-21 05:56
you need to get the files into the peer containers - through manual means, rebuilding the container or fetching from a website
abhishekseth
2016-07-21 05:56
ok. sounds good
abhishekseth
2016-07-21 05:56
thanks
bgorman
2016-07-21 05:56
let me know if you have trouble
abhishekseth
2016-07-21 06:03
@bgorman: I run make peer-image command. Then I started peer again and tried to deploy the new chaincode. But still it gives me the same error.
bgorman
2016-07-21 06:03
ok, maybe you need to make peer-image-clean first
bgorman
2016-07-21 06:04
let me have a go at this too
bgorman
2016-07-21 06:05
oh... you'll have to stop and remove the peers, then restart them too
bgorman
2016-07-21 06:06
otherwise the new image won't be used for the containers
abhishekseth
2016-07-21 06:12
i stopped the terminals on which the peers were running, make peer-image-clean, make peer-image and then i started everything again and tried to deploy but this does not help.
bgorman
2016-07-21 06:13
your machine is a lot faster than mine... I'm still running `make peer-image`

maybe run `docker exec -it <container_name> bash` and check if your .go files are in there
bgorman
2016-07-21 06:22
ok perhaps I misunderstood how the peer containers get made... I thought they were based off the local disk, but they may just get downloaded from the internet :confused:
bgorman
2016-07-21 06:27
ok that's wrong too.... it downloads a base image but layers file git is tracking on top...
bgorman
2016-07-21 06:28
so... @abhishekseth you may want to `git add <your_files>` then run `make peer-image` again

Hi Guys do we have any document comparing different consensus algorithms used by different frameworks
jcarrivick
2016-07-21 06:32
@pranob: The only two consensus algorithms are `noop` which just blindly accepts everything and Byzantine Fault Tolerance which can tolerate `(n-1)/3` out of `n` nodes being faulty
bgorman
2016-07-21 06:33
he mentioned other frameworks... so presumably Proof of Work (bitcoin and co) and Sawtooth's Proof of Elapsed Time would be compared as well?
bgorman
2016-07-21 06:33
I've not seen a comparison, but then they're really quite different
pranob
2016-07-21 06:41
@bgorman: from frameworks perspective i am looking at Eris, Ethereum and hyperledger
pranob
2016-07-21 06:41
or any other blockchain framework
abhishekseth
2016-07-21 06:45
@bgorman: Problem solved! You were right in that the peers are not able to see the chaincode. I went into the containers and added the chaincode file and now it works fine. Thanks a lot!
bgorman
2016-07-21 06:50

i am executing a chaincode (as docker container). its successful. Invoke and Query also successful. I wanted to see the print output in the chaincode. In documentation it says to check in chaincode window. . itseems they are referring to Vagrant . In my setup .. i dont have vagrant .. is there a way to see the chaincode print statement output some where in the linux console.

It generates some hash but also it throws some error on peer terminal and i think due to this, my invoke and query functions are not working. This is the snap shot of the error. It says that container is not able to build docker image.
Any help is appreciated.
muralisr
2016-07-21 12:02
@abhishekseth: it is likely due to an error building the chaincode(the “go install” part of the command)
muralisr
2016-07-21 12:02
did you try it in —peer-chaincodedev mode and make sure it works there first ?

I have one question on membership service. When we run a Hyperledger based solution across multiple participants (e.g. enterprises), who should take the role to operate the membership service? Should it be a trusted independent 3rd party? What if the participants can not agree on one trusted membership service operator?

Since fabric does not pick up the dependencies involved, we are supposed to add those packages in the vendor folder. I tried to add this package in the vendor folder using “govendor add +extrernal” command. But after that, member services start throwing error and do not get up. Here is the snap shot of the error.
bgorman
2016-07-22 05:42
@abhishekseth: encoding/json is part of the core golang packages, are you sure you couldn't just use it in the chaincode?
bgorman
2016-07-22 05:43
there are example chaincodes that use it like examples/chaincode/go/map/map.go (I admittedly haven't used that one)
abhishekseth
2016-07-22 05:46
yeah, that is the part of the core golang packages but it needs to be added in the vendor folder otherwise fabric does not pick up. Here is the reference link: http://stackoverflow.com/questions/38293279/error-starting-container-api-error-500-hyperledger
bgorman
2016-07-22 05:49
that's talking about a package that isn't part of Go itself though
abhishekseth
2016-07-22 05:56
It used my old vendor folder and member services are now up. But the previous problem still remains same i.e. the chaincode having encoding/json package shows error of “building image” when i try to deploy.
bgorman
2016-07-22 05:57
did you try running `go install http://github.com/hyperledger/fabric/examples/chaincode/go/patient` ?
abhishekseth
2016-07-22 06:02
yeah, but it doesn’t show any error
bgorman

so I need both docker-compose-files/hyperledger/ and docker-hyperledger-peer @ashnur ?

the compose files are just to start them, you need all the peer images you want to use of course

docker-compose is a separate tool from docker
mart0nix
2016-07-25 14:58
yeah I understand
mart0nix
2016-07-25 14:58
but I'm confused as I thought the hyperledger fabric docker image will also include the peer stuff
ashnur
2016-07-25 14:59
i am not good with names, so i don't know which is which. I know that there is basically 2 images that I used. both from yeasy one the membersrvc and the other for the peers
ashnur
2016-07-25 14:59
and these are the two that were in the docker-compose file too
mart0nix

[Hyperledger in scale]
Since Hyperledger use an internal /var/hyperledger/db as to store the database, and we actually need to mount this directory outside of its container.
Generally, I can mount each specific mount to each container using a static docker-compose file.
So in case of scaling the node with docker-swarm, how can I mount the separated volume directory to each different node?

I'm trying to find out about the process of validating a block.
As far as I am aware, the hashing function is SHA-256. Does anybody know what parameters are passed, and what data is actually hashed?
jake.turner
2016-07-26 14:47
To clarify, I'm referring to how an individual block hash is generated.

Hey all,
If i want to enable user in “outside of vagrant” mode i.e. security enabling in “outside of vagrant”, what are we supposed to do?
Are we supposed to add some security attributes in docker-compose.yml file?

you may want to use the vagrant devenv
bgorman

did you install Oracle VirtualBox?
vajadhav
2016-07-29 06:00
yes
bgorman
2016-07-29 06:01
great, you should be able to `cd $GOPATH/src/github.com/hyperledger/fabric/devenv`
bgorman
2016-07-29 06:01
then `vagrant up`
vajadhav
2016-07-29 06:01
with vagrant up I have created hyperperledger
bgorman
2016-07-29 06:01
if it completes you should be able to run `vagrant ssh` and be in a development environment with all the tools you need
vajadhav
2016-07-29 06:01
yes done with vagrant ssh as well
bgorman
2016-07-29 06:02
so you don't have `make` inside your vagrant?
bgorman
2016-07-29 06:02
it should be at `/usr/bin/make`
vajadhav
2016-07-29 06:03

2016-08-01 12:31
@matpasha: you should use the peer’s IP address in docker instead of “0.0.0.0” in CORE_PEER_ADDRESS
muralisr
2016-08-01 12:32
also, fabric questions should be addressed in relate channels such as “fabric”, “fabric-dev”, “chaincode”….

Hey all,
I am working in outside of vagrant setup using docker images. I have peers and member services up and running. Also, I am able to deploy and run chaincodes.
Now, I have two physical machines each having same setup and 2 peers running on each machine. How do I communicate between the peers on one machine and the peers on different machine?
bgorman
2016-08-02 05:14
@abhishekseth: you need to have a reachable port for each peer on machines 1 and 2
bgorman
2016-08-02 05:15
when starting up each peer, set its CORE_PEER_ADDRESS to the reachable address:port
bgorman
2016-08-02 05:16
and probably set CORE_PEER_ADDRESSAUTODETECT=false while you're at it
bgorman
2016-08-02 05:18
e.g. machine1 opens ports 30303 and 30304 for vp0 and vp1,
so you'd start vp0 with CORE_PEER_ADDRESS=http://machine1.domain.com:30303
and then vp1 would have CORE_PEER_ADDRESS=http://machine1.domain.com:30304 CORE_PEER_DISCOVERY_ROOTNODE=http://machine1.domain.com:30303
abhishekseth
2016-08-02 05:19
see, I am using docker-compose up to start peer and member services. It uses docker-compose.yml file to take the config details. I think all the changes must be made in this file only, right?
bgorman
2016-08-02 05:19
I don't know much about docker-compose but can you set environment variables for the processes in the containers it brings up?
bgorman
2016-08-02 05:20
normally when running just `docker ` it uses the `-e` flags to do so
abhishekseth
2016-08-02 05:23
no, i think that using docker-compose command, I can not set the variables. But yeah, I can change these things in docker-compose.yml file and those changes will reflect in the peers
abhishekseth
2016-08-02 05:26
@bgorman: If i set the address and discovery-rootnode for the peers on both the machines the way u mentioned, would I be able to communicate between them?
bgorman
2016-08-02 05:26
if it's done correctly, yes
bgorman
2016-08-02 05:28
you'll also need to ensure the ports are exposed at the docker and machine levels, then traffic is routable between the machines as well, of course
abhishekseth
2016-08-02 05:30
okay, I will try.

How does one query the transaction history of an item in the ledger? For example, given key X and PutState(X, Y), followed by PutState(X,Z)… is there an API for following/linking those transactions so that I can see X was first Y and then Z, or is that left to application level logic?

Hey folks, may I ask that is there any particular reason that fabric transfers from Github to Gerrit? Just out of curiosity, would be great if anyone would tell me or throw me some insights (emails/discussion records, etc). Thanks!
jonathanlevi
2016-08-03 02:38
Hi @dinghaiyang84, there were several discussions about this... and a long presentation by @cbf and @ry, but among the key differences are multiple reviewers (requiring two `+2`s for a merge), better granularity (-2, -1, 0, +1, +2) in the reviews, the ability to look into each file version in a patch-set along with multi-party discussions inline per file (patchset) version.
jonathanlevi
2016-08-03 02:40
I am sure this list of upsides is not exhaustive - the one thing I do miss from GitHub is its more extensive markdown (syntax formatting). But maybe this can be added as a plug-in or so?
dinghaiyang84
2016-08-03 03:00
Hi @jonathanlevi, thanks for the reply. Is there any records of the presentation? I am interested in the difference between Github and Gerrit, and I think learning with the "long presentation" is a good way to do that. Plus I could know more about the development style of fabric.
ry
2016-08-03 03:01
@dinghaiyang84: I don’t think there was a recording of it. It wasn’t on the schedule - @cbf was going to talk about something else and I kind of took over
dinghaiyang84
2016-08-03 03:04
@ry, thanks for the information. Best regards
ry
2016-08-03 03:05

2016-08-03 03:05

ry

Quick question, As git repo is currently a read-only repo not accepting pull requests, what would be the best way to contribute to the project
maltaf
2016-08-04 02:11
like joining the dev team etc
maltaf
2016-08-04 02:15
Thanks @baohua , would I be able to generate PR on this repository?
maltaf
2016-08-04 02:16
or I'll have to submit the patch
baohua
2016-08-04 02:16
certainly, let me find the doc for u
maltaf
2016-08-04 02:16
sure
maltaf
2016-08-04 02:17
how frequently is the git repo updated?
baohua
2016-08-04 02:19
see the latest doc here http://cbf-fabric-docs.readthedocs.io/en/latest/CONTRIBUTING/, soon it will be merged into the official one.
baohua

there is no regular update now, will be setup later
maltaf

maltaf
2016-08-04 02:21
Another question. is there a path to becoming committer to this project?
jonathanlevi
2016-08-04 02:25
Nope, it's pretty straight-forward. Once you have your user, you clone the repo, code and you can submit a patch set for review...
jonathanlevi
2016-08-04 02:27
[@maltaf note that it's not really a PR (which is the "GitHub's way") with Gerrit - but yes, it's pretty open to contributions]
maltaf
2016-08-04 02:28
Thanks @jonathanlevi I understand that
maltaf
2016-08-04 02:29
What I mean is that if someone wants to become a commiter or be pat of the dedicated team, is ther a process? like he should have x number of contributions or should be a contributer for y number of years etc
maltaf
2016-08-04 02:29
or perhaps there is a training that can lead to becoming a committer in short time
maltaf
2016-08-04 02:30
like Pivotal dojo for cloud foundry etc
jonathanlevi
2016-08-04 02:31
I see what you are asking. I don't know of any formal training. Some individuals contribute on their own, others contribute as part of their professional work.
baohua
2016-08-04 02:31
no, this project is open for every LF user currently. no training is required.
jonathanlevi
2016-08-04 02:32
But yes, you/one can pick up issues and fix them, suggest improvements, submit proposals, participate in discussions and regularly attend the various WGs.
jonathanlevi
2016-08-04 02:33
(There are several Working Groups, dedicated to particular topics...)
maltaf
2016-08-04 02:33
Sounds cool. Probably I'll be intersted to attend some of the WG meetings
maltaf
2016-08-04 02:34
any link or reference the calendar for the timings of these meetings
jonathanlevi
2016-08-04 02:38
Yes, it's really nice. Seriously. I have to admit that, at times, I am stunned myself by how open HL is.
jonathanlevi
2016-08-04 02:39
I suggest spending some time on this: https://github.com/hyperledger/hyperledger/wiki/Requirements-WG-Members and https://github.com/hyperledger/hyperledger/wiki/PublicMeetingCalendar
jonathanlevi
2016-08-04 02:40
There is a menu on the right with about 106 pages. Knock yourself out :wink:
maltaf
2016-08-04 02:40
Thanks @jonathanlevi , I'll go through this page
jonathanlevi
2016-08-04 02:40
But do come back with more questions!

hi everyone - how mature is the Java shim support currently for chaincode development?
venkat
2016-08-04 09:14
Is it just as good as golang chaincode?
venkat
2016-08-04 09:16
I ask this because, there is whole lot of existing business code in Java, which may need to be converted into smart contracts / chaincode. And there is an easily available Java skilled resource pool compared to golang.
venkat
2016-08-04 09:16
So what do you think of using Java instead of Golang for chaincode development?
abhishekseth
2016-08-04 10:28
Hey all, I am running the setup outside of vagrant which uses docker compose to run peer and member services.
When we are in dev mode, it works fine but we we go out of that mode and come to network/production mode, containers for the chaincode should have been created for all the peers.
But in my case, it is throwing error saying “not able to build images and hence not able to create containers."
abhishekseth
2016-08-04 10:29
Any pointer or help is appreciated.
satheesh
2016-08-04 15:05
@venkat: I wouldn't call the Java shim support as mature yet, but it is slowly catching up with goland counterpart. There are couple of releases planned for Java chaincode development. The first one carries huge re-organizaion of the project structure to make it easier for chaincode development easier, and a separate java docker image for chaincode deployment. It also gets support for range queries. This will be pushed to gerrit in a day or two.
satheesh
2016-08-04 15:08
@venkat: Spec wise it will soon reach golang's equivalence. Table support is in progress.

And yes you are correct, we started this with the objective to make existing java business code reusable in the hyperledger/chaincode environment

hi there, from what I google so far. At this moment, state change is not recorded in ledger (only in proposed next generation architecture)
ibmdannywong
2016-08-04 15:49
the state only stores the latest value
ibmdannywong
2016-08-04 15:50
the ledger only stores transaction invocation history (which func is called, what input param, and result hash)
ibmdannywong
2016-08-04 15:51
I read the source code as well.. and seems my understanding is correct... is that anyone on the same page with me?
simon
2016-08-04 15:55
the ledger only stores current state
simon
2016-08-04 15:55
the blockchain stores transactions
simon
2016-08-04 15:55
there is some side table that stores the changes of transactions

Hi all,
In go, only these are the column types supported? anyone is aware if we can store the complex types like os.File ?
ColumnDefinition_STRING
ColumnDefinition_INT32
ColumnDefinition_INT64
ColumnDefinition_UINT32
ColumnDefinition_UINT64
ColumnDefinition_BYTES
ColumnDefinition_BOOL
Please share your thoughts.
bgorman
2016-08-05 03:24
@pushpalatha: that's a Hyperledger/RocksDB thing ... you could always serialise your file into []bytes
pushpalatha
2016-08-05 04:37
@bgorman: Thank you so much for the quick response. I was wondering if rock's db supports complex files types like, pdf, images, cvs, xml etc. But I guess no. Hence thought that if you guys have come across any such scenarios and any workarounds for the same.
bgorman
2016-08-05 05:12
@pushpalatha: if you really want to store files in a blockchain, you could just store them as bytes keyed to a filename
grapebaba
2016-08-05 05:14
yep, why need store files in DB?just need store info which can find the file on server
jonathanlevi
2016-08-05 05:22
[While I don't know enough about the use-case need, FWIW:]
Another technique is to `hash(something)` where `something` is uniquely identifying what was hashed.
jonathanlevi
2016-08-05 05:23
So some people store a hash of a document (or a URL to the document) and then they can prove that a block that was added to the blockchain contained a ("timed") hash of that doc.
jonathanlevi
2016-08-05 05:24
... where one may or may not want to reveal the context of that `something`.

Does the make behave test suite for Hyperledger require Python 2.7.X or Python 3.X?
jonathanlevi
2016-08-05 22:59
Both are supported [by the Behave framework], but I believe we run it using Python 2.7
jonathanlevi
2016-08-05 22:59
... which is located in `/usr/lib/python2.7` in our vagrant/vbox image.

Are you trying to upgrade to Ubuntu 16.04 (with python3 as the default) or so?
jonathanlevi
2016-08-05 23:04
We can start thinking about upgrading our image at some point (so while Behave supports it, we might need to revisit/upgrade the testing code).
The above is just my quick 'first aid'. Jeff Garret is our Behave guru...

@garisingh: How to logout? You can run “peer network login” to login or POST to registrar through REST API, but there is no logout command
garisingh

@alexho: use a DELETE with the `/registrar/{enrollmentID}` endpoint

@alexo - yep. sorry - that is what I was trying to say earlier. I just commented here: https://jira.hyperledger.org/browse/FAB-2
garisingh
2016-08-06 14:12
hopefully that will help explain what is happening - but the bottom line is that "logging out" with the REST API is not really like logging out in the classic sense.
garisingh
2016-08-06 14:13
Using the NodeSDK is the way to go moving forward
alexho
2016-08-06 14:15

unfortunately not

Hi everyone, i am trying to deploy my go chaincode. I am using a single validating peer to test it. I always get the following error:
Error: Error querying chaincode: rpc error: code = 2 desc = "Error:Failed to launch chaincode spec(Could not get deployment transaction for 398527d587b2497815e2a1ed4ae4c651ad61f80736c4b634d6ea2d5b44bc17cc2fe738340720690eb782e44189b339da714b7aa3686c4b30cb3dd994e0a559be - LedgerError - ResourceNotFound: ledger: resource not found)"
Is there a way to check if the deployment was successful? I have tried to deploy a non compiling go code too, and it did not complain......
garisingh
2016-08-07 15:45
@szlaci83: one easy check is to see if the Docker container for your chaincode is actually created and running - e.g. `docker ps` or `docker ps -a`
szlaci83
2016-08-07 15:45
thanks @garisingh
szlaci83
2016-08-07 15:48
@garisingh: for the compiling chaincode I have the containers so deployment seem to be successful, but at query i still get the same error..... any idea?
garisingh
2016-08-07 16:24
@szlaci83: when are you getting this error? when trying to run a query or an invoke on the actual chaincode?
garisingh
2016-08-07 16:25
it may be that you are using the wrong identifier for the chaincode
szlaci83
2016-08-07 16:26
@garisingh: thanks for the quick response.... i am still trying, it seems i called the Query too quick in a script , and the docker container was not ready yet...:smile: i should be ok now. Thanks
garisingh
2016-08-07 16:28
yeah - generally you have to wait some period of time before calling the initial query / invoke

if you're using the gerrit code, I think it has port 7053

@pushpalatha: oh ok.... can you see port 31315 listening with `netstat -na |grep 31315` ?
bgorman
2016-08-08 07:11
you might need to run block-listener inside the peer container, or have the peer's docker image publish the port externally

I've noticed that fabric has moved its repo to gerrit. Based on standard go code conventions - in which the directory structure is supposed to match the repository location - this implies that this is supposed to be stored in something like http://gerrit.hyperledger.org/r/fabric, as that's the clone directory gerrit gives. However, the code still assumes that all packages are in http://github.com/hyperledger/fabric. While I could just move the code to the correct location, and work with that, it seems an inelegant method of getting new code. It makes me think I'm missing something about how I'm supposed to be getting new versions. What is the proper way of importing the code from gerrit?
garisingh
2016-08-08 19:22
@davisbroda: I'll let @cbf or one of the maintainers correct me, but for now you should still clone from Gerrit into the previous location (e.g. $GOPATH/src/github.com/hyperledger/fabric). I believe that once things are up and running, the github repo will be a mirror of Gerrit and then all imports will continue to work
davisbroda
2016-08-08 19:28
thanks for the update @garisingh I'll do that until they sync the two repos

@abhishekseth: i m working inside vagrant, and i m trying to a simple development environment setup.

if anyone else is having the docker "HostConfig" errors, make sure you're using the latest code from http://gerrit.hyperledger.org/r/fabric (not github)
gaurav
2016-08-10 06:58
@bgorman: moving to gerrit from guthub, should also then resolve the "LedgerError - ResourceNotFound" errors on query/invoke api's, since this issue results because of previous errors during deployment of the chaincode

Hi all,
lyriarte
2016-08-11 09:51
I'm having problems with chaincode parameters after sync'ing from gerrit
lyriarte
2016-08-11 09:52
past change eacd0e0de3a0d147efea0278e69bddb8709174ef
lyriarte
2016-08-11 09:52
Merge "Use repeated bytes instead of repeated string for chaincode call args"
lyriarte
2016-08-11 09:53
I'm building peer and chaincode_example02
lyriarte
2016-08-11 09:54
I get the following error when invoking the chaincode as
peer chaincode deploy -n example02 -c '{"Function":"init", "Args": [ "a", "200", "b", "100" ] }'
Error: Chaincode argument error: illegal base64 data at input byte 0
lyriarte
2016-08-11 09:55
I'm working outside gerrit, running the peer in --peer-chaincodedev mode
lyriarte
2016-08-11 09:55
same thing works fine @f1b6762f569852f1fa75bd9a280507c3178fbe6d
lyriarte
2016-08-11 09:56
Also, I did a clean build for the peer.
lyriarte
2016-08-11 09:59
If I understand correctly, I should not have to rewrite chaincode since change fd498d2fa7fdc048b4150db1a15eef572f536a87 makes no change to chaincode_example02, but just to examples 04 and 05 that call into example 02 ?

lyriarte: what path did you clone to?
hgabor
2016-08-11 11:25
the problem is that 200 and 100 arent base64
simon
2016-08-11 11:26
wait, why does it have to be base64?
hgabor
2016-08-11 11:26
since Merge "Use repeated bytes instead of repeated string for chaincode call args"
hgabor
2016-08-11 11:26
args are bytes
simon
2016-08-11 11:26
yes
simon
2016-08-11 11:26
and the REST api now expects base64?
hgabor
2016-08-11 11:26
yes it does
simon
2016-08-11 11:27
i see
simon
2016-08-11 11:27
that's inconvenient
simon
2016-08-11 11:27
i see
hgabor
2016-08-11 11:27
i ve also modified the corresponding tests in that commit, to use b64
simon
2016-08-11 11:27
that's the reason
simon
2016-08-11 11:28
maybe that should be a different REST api call?
simon
2016-08-11 11:28
oh i don't know
hgabor
2016-08-11 11:28
maybe we could add some conversion for the command line
gaurav
2016-08-11 11:28
Can someone please point or share some documentation on Hyperledger Fabric Client (HFC) for Node.js, I wish to explore it features, capabilities
simon
2016-08-11 11:28
hgabor: i guess
hgabor
2016-08-11 11:28
I think that is OK if the REST needs b64
simon
2016-08-11 11:28
bloats everything tho
simon
2016-08-11 11:29
silly json
hgabor
2016-08-11 11:29
it is not OK if the command line needs it
simon
2016-08-11 11:29
ideally there would be a way to use strings or b64
simon
2016-08-11 11:29
but json can't distinguish them
simon
2016-08-11 11:29
so yea
hgabor
2016-08-11 11:30
1st we should investigate if there is a way to use string in the REST
hgabor
2016-08-11 11:30
I am not sure there is
hgabor
2016-08-11 11:35
who is the expert of the REST api?
gaurav
2016-08-11 11:39
i need more than setup information, information like how to retrieve chain related information like chain height, transaction details, and to explore event related capabilities of hyperledger from HFC
simon
2016-08-11 11:40
lyriarte: no, to which directory locally
lyriarte
2016-08-11 11:40
~/git/hyperledger/fabric
lyriarte
2016-08-11 11:40
that's outside vagrant
lyriarte
2016-08-11 11:41
I don't understand how it is relavant ?
lyriarte
2016-08-11 11:41
BTW I got the issue using the CLI, not REST
lyriarte
2016-08-11 11:41
REST worked before (@f1b6762f569852f1fa75bd9a280507c3178fbe6d)
lyriarte
2016-08-11 11:42
but I haven't even bothered fixing my web clients since I couldn't even get the CLI to work
hgabor
2016-08-11 11:44
@lyriarte: I dont think this has anything to do with the place where you cloned your repo to
lyriarte
2016-08-11 11:44
sure
ashnur
2016-08-11 11:44
gaurav: the url is misleading, you can find a lot of information there, not just about setup
hgabor
2016-08-11 11:45
@lyriarte: the problem is the b64 thing we described below
lyriarte
2016-08-11 11:45
I get that, but what should I do about it ?
hgabor
2016-08-11 11:45
I am looking at the REST code now to sort this out
hgabor
2016-08-11 11:46
lets suppose that I am able to fix it, this way you have to use the fix, and for now you can use master HEAD^1 :slightly_smiling_face:
hgabor
2016-08-11 11:46
if I am unable... that s another story :slightly_smiling_face:
lyriarte
2016-08-11 11:46
But just using the Command Line Interface is broken also, what's the REST supposed to do with it ?
lyriarte
2016-08-11 11:47
Well anyway I'm @f1b6762f569852f1fa75bd9a280507c3178fbe6d and I'm fine, working with the new 705x ports
hgabor
2016-08-11 11:47
the REST wants base64 instead of string like "100"
mohan
2016-08-11 11:47
@gaurav: Yes @ashnur is right. It has lot of information other than setup. Just dig through the links
lyriarte
2016-08-11 11:47
@hgabor: oh... painful.
hgabor
2016-08-11 11:48
and the command line sends just simply what you give to it
lyriarte
2016-08-11 11:48
ok... any example in the documentation ?
simon
2016-08-11 11:48
lyriarte: no, that won't work
hgabor
2016-08-11 11:48
from a program it is no so painful to create a b64 thing and pass that
simon
2016-08-11 11:48
lyriarte: you need to put it in your GOPATH in http://github.com/hyperledger/fabric
lyriarte
2016-08-11 11:49
sure, from a JS web client that would be ok
simon
2016-08-11 11:49
or go will pick up the old files
hgabor
2016-08-11 11:49
@lyriarte: maybe the docs are outdated, please link me those and I will try to fix it or ask somebody who is more familiar :slightly_smiling_face:
lyriarte
2016-08-11 11:51
@simon: my GOPATH is ok, the peer executable I'm running is just a symlink in /usr/local/bin to the one I'm building in build/bin/peer
simon
2016-08-11 11:51
where is your GOPATH
lyriarte
2016-08-11 11:52
/home/lyriarte/obc-distrib/docker:/home/lyriarte/obc-distrib/obc-vendor:/home/lyriarte/obc-distrib/openblockchain
lyriarte
2016-08-11 11:53
the hyperledger sources are the last ones (openblockchain)
lyriarte
2016-08-11 11:53
I started from the github/openblockchain repo, then added a remote to github/hyperledger, then another remote to thehyperledger gerrit
lyriarte
2016-08-11 11:55
@simon: Should I have only one folder in my GOPATH ? In case the docker sources take precedance ?
simon
2016-08-11 11:55
what docker sources?
lyriarte
2016-08-11 11:56
/home/lyriarte/obc-distrib/docker
lyriarte
2016-08-11 11:56
They are also in my GOPATH as I used to build docker - older linux version, I built go + docker from sources
simon
2016-08-11 11:56
no, my point is that the hyperledger sources need to be in gopath
lyriarte
2016-08-11 11:57
they are: /home/lyriarte/obc-distrib/openblockchain
lyriarte
2016-08-11 11:57
that's where I pulled them.
simon
2016-08-11 11:58
you said they're in ~/git/hyperledger/fabric
lyriarte
2016-08-11 11:59
sorry, symlink. look:
lyriarte
2016-08-11 11:59
lyriarte@lyriarte-e5410:~/git/hyperledger/fabric$ ls -al /home/lyriarte/obc-distrib/openblockchain/src/github.com/
lyriarte
2016-08-11 11:59
lrwxrwxrwx 1 lyriarte lyriarte 30 juin 30 11:06 hyperledger -> /home/lyriarte/git/hyperledger
simon
2016-08-11 11:59
ah!
simon
2016-08-11 12:00
then it is not the problem i thought it was
lyriarte
2016-08-11 12:00
I moved my sources around and symlinked everywhere since openblockchain -> hyperledger -> gerrit
lyriarte
2016-08-11 12:00
so yeah it's a symlink spaghetti plate right now
simon
2016-08-11 12:00
i think hgabor is looking at the source
lyriarte
2016-08-11 12:01
but I guess my issue is more the base64 thing @hgabor mentionned
simon
2016-08-11 12:01
yea
hgabor
2016-08-11 12:01
yes definitely
lyriarte
2016-08-11 12:02
Anyway, encoding everything in b64 is ok for the REST API I guess but for the CLI it's painful
hgabor
2016-08-11 12:03
yes I see it the same way
hgabor
2016-08-11 12:03
it seems now that the easy way of fixing this is to modify the cli
hgabor
2016-08-11 12:04
what do you think?
lyriarte
2016-08-11 12:04
If you can upload a patch on gerrit for the CLI I'll try it out
lyriarte
2016-08-11 12:04
That seems to make sense to encode REST in base64
lyriarte
2016-08-11 12:05
but use CLI as plain text
simon
2016-08-11 12:06
right on
lyriarte
2016-08-11 12:07
Ok, so I'll keep an eye on gerrit, and try to update my Javascript code to work in base64 with the latest peer
lyriarte
2016-08-11 12:07
Thanks you guys for explaining.
lyriarte
2016-08-11 12:16
@hgabor: regarding the documentation, I'm using docs/API/CoreAPI.md for reference, and @acac0e98ffd12ecb1c8cd6f766b020bd343a2991 the REST API sample still shows plain text in the JSON args.
lyriarte
2016-08-11 12:17
POST host:port/chaincode .... "args":["a", "1000", "b", "2000"]

@lyriarte: it seems that there is a JSON parsing in the CLI client itself
hgabor
2016-08-11 12:49
you give something to is and it tries to parse it as a json
hgabor
2016-08-11 12:50
and go json decoder wants []byte as base64. I do not know if there is any way to workaround this
safitudo
2016-08-11 12:52
Hi all,
I have few general architecture questions: Will appreciate any input on this (may be in private chat not to bother others).
In our project, transaction entity has 4 states. Each state and entity itself has some properties. Is it effective to store that data in shim (chaincodeStub) tables? What are the alternatives? What if data should be easy to access and filter by parties?
lyriarte
2016-08-11 12:56
@hgabor: So that means parsing the JSON structure, and replacing the "args" array in the resulting hash with an array containing the b64 representations of each item? Oh well...
lyriarte
2016-08-11 12:57
BTW, looking at the source it seems that the "function" argument needs to be converted in b64 as well ?
hgabor
2016-08-11 12:58
Please have a look at protos/chaincode.proto
hgabor
2016-08-11 12:58
I remember there is no function parameter now
hgabor
2016-08-11 13:01
function is just an argument if you need one
hgabor
2016-08-11 13:02
you can also pass encoded structures as the arguments are just bytes
hgabor
2016-08-11 13:02
you can have "more than one functions"
lyriarte
2016-08-11 13:03
ok, looking at the json samples you something like:
lyriarte
2016-08-11 13:04
"ctorMsg": {"function":"query", "args":["a"]}
lyriarte
2016-08-11 13:04
but in the chaincode.proto
lyriarte
2016-08-11 13:04
I can see that
hgabor
2016-08-11 13:05
yeah it turns out that the docs are out of date
lyriarte
2016-08-11 13:05
message ChaincodeSpec {.... ChaincodeInput ctorMsg = 3; ....
simon
2016-08-11 13:05
ok, rest_api.go is a spaghetti maze
hgabor
2016-08-11 13:05
I will have to fix those
lyriarte
2016-08-11 13:05
and message ChaincodeInput {
repeated bytes args = 1;
}
hgabor
2016-08-11 13:05
@simon for lyriarte it is the peer/main.go that fails json unmarshalling
lyriarte
2016-08-11 13:06
so actually ctorMsg is now a byte array.
hgabor
2016-08-11 13:06
yes
lyriarte
2016-08-11 13:07
@hgabor: One thing though: The callbacks signatures in chaincode examples are still like that:
lyriarte
2016-08-11 13:07
func (t *SimpleChaincode) Invoke(stub *shim.ChaincodeStub, function string, args []string) ([]byte, error) {
lyriarte
2016-08-11 13:08
So from the chaincode perspective there's one single "function" parameter.
simon
2016-08-11 13:09
yes
hgabor
2016-08-11 13:09
yeah that remained is it were. chaincode API change will come in another step: the chaincode will have to use stub to get all the args. stub.GetArgs() return [][]byte
simon
2016-08-11 13:10
oh while we're in there we need to change the chaincode api
lyriarte
2016-08-11 13:10
ok so it's not the shim layer underneath that's going to translate the arguments.
simon
2016-08-11 13:11
not in the long run
lyriarte
2016-08-11 13:11
will the "function" arg still have some kind of special statusus though ?
lyriarte
2016-08-11 13:11
I mean, is this:
lyriarte
2016-08-11 13:11
"ctorMsg": {"function":"query", "args":["a"]}
lyriarte
2016-08-11 13:11
still valid ?
simon
2016-08-11 13:11
no
lyriarte
2016-08-11 13:11
okay
lyriarte
2016-08-11 13:12
good to know, I was starting to rely on it as a selector.
simon
2016-08-11 13:12
well i suggest for the cli we can just unmarshal an array of strings
simon
2016-08-11 13:12
and cast them to bytes?
simon
2016-08-11 13:12
does that seem reasonable?
simon
2016-08-11 13:12
lyriarte: now you can just use the first argument as selector
simon
2016-08-11 13:13
we need to change the chaincode API so that you don't pass in an object to the shim
lyriarte
2016-08-11 13:13
@simon: sure, that does'nt prevent anything.
simon
2016-08-11 13:13
but a factory function
lyriarte
2016-08-11 13:13
makes sense
simon
2016-08-11 13:14
people are tempted to store state in the object across invocations
lyriarte
2016-08-11 13:16
kind of kills the purpose of a "REST" API then, especially when you have a blockchain to store state if you need that.
hgabor
2016-08-11 13:18
@simon what kind of factory function you me, explain please

@zsolt: I using docker-compose up to start my peer and membersrvc which reads docker-compose.yml for config and stuff.
zsolt
2016-08-11 15:00
current docker, or the beta?
abhishekseth
2016-08-11 15:04
beta
zsolt
2016-08-11 15:16
it did not work for me with the beta (but with a different error), last time I`ve tried it is about a month ago. I didn’t dive deeper into the problem at that time
abhishekseth
2016-08-11 15:18
Are u working in outside of vagrant setup right now?
zsolt
2016-08-11 15:39
i moved to inside vagrant, as it cause too much hassle to maintain the outside-of-vagrant build working
abhishekseth
2016-08-11 15:42
hmm...
simon
2016-08-11 15:44
lol
simon
2016-08-11 15:44

The tutorial assumes that vagrant and virtualbox are going to work without issues, but I keep hitting walls...It seems to point to virtualbox more than vagrant.

I am going to say no since I was following the tutorial, and the first steps are to ensure that vagrant and vbox are installed. Are there other instructions I should be following? Can you link me?
boydjohnson
2016-08-11 19:16
Yeah, check out https://github.com/hyperledger/sawtooth-docs/issues/10. The tutorial is out of date right now but in the next two weeks should be up-to-date. That github issue shows how some of the Marketplace tutorial issues can be fixed.

2016-08-11 19:36
thanks for the link...when you ask if I am using the sawtooth-dev-tools Ubuntu vagrant vm, can you expand on that? I am on an Ubuntu 14.04 vm. I've cloned the stl files from github, and have tried multiple times and ways to get virtualbox to work, but it does not. Is the vm you reference within the dev-tools folder structure? I am not used to feeling like such a noob, thanks for the help...
jce23
2016-08-11 19:36
I should be clear, I am not seeing anything in the link you provided that will help me right now.

@jce23: I don’t think running VirtualBox inside a VM is supported.
jce23
2016-08-11 20:06
•Note that your Host should not run within a VM. If you attempt this, the VM within your Host may fail to boot with a message indicating that VT-x is not available.
The above is from the Fabric docs. Should I take this to mean that they (STL and/or Fabric) should be installed on physical hosts, not cloud-based or other VMs?
rbuysse
2016-08-11 20:07
You can install Sawtooth directly onto a VM
jce23
2016-08-11 20:09
ok, so follow up the sys admins guide for STL then if using a VM?
rbuysse
2016-08-11 20:33
yeah the sysadmin guide might be a better place to start. The Transaction Family section of the Tutorial will help you understand the system a little better so that is worth a read too.

Thanks. But I am searching specifically if there are APIs part of HFC SDK for Node.js for retrieving transaction details, chain heights, a particular block details(say block no. 10), etc. These capabilities are present as part of the REST API through the /chain, /chain/block/{blockNumber} REST interface. So i am looking for similar API's interfaces in the HFC SDK for Node.js if there.

we took out the default config file and instead set defaults within the validator code. Those can still be overridden by a config file -- see the example in validator/etc
middleton
2016-08-12 14:37
Also I changed the default PoET timing for 5 second interblock timing. The original default settings were for 25 node networks but these settings are more useful for quick turn experiments developers are doing with smaller networks.

@vijayr24: if you are going to use CORE_PEER_ADDRESS=0.0.0.0:30303 you will need to set CORE_PEER_ADDRESSAUTODETECT=true
otherwise you need to set CORE_PEER_ADDRESS to a valid hostname/IP that other machines can connect to

So the last error is thrown at the REST API layer right after marshalling the login spec.
maltaf
2016-08-16 03:28
ok
jonathanlevi
2016-08-16 03:28
Seems like the lookup for the EnrollmentID could not be found.
jonathanlevi
2016-08-16 03:29
I need some more info as for how you run it...
maltaf
2016-08-16 03:29
sure
jonathanlevi
2016-08-16 03:29
(and to be clear, these error messages are not clear!)
maltaf
2016-08-16 03:29
Agreed

(don't think these have gone unnoticed)

2016-08-16 03:30
I am starting membership service first and then the peer node in a development environment
maltaf
2016-08-16 03:31
then I start the car-lease-demo app using node server
maltaf
2016-08-16 03:31
the demo tries to create the users
maltaf
2016-08-16 03:31
this is when these errors appear
maltaf
2016-08-16 03:32
I deployed this to Blumix, and it worked without any issue
maltaf
2016-08-16 03:32
So I guess there is some specific setup configuration that I am missing
jonathanlevi
2016-08-16 03:32
Yes, that's what I think too.
jonathanlevi
2016-08-16 03:33
I can't see the setup - I understand, but I can try to give you more info.
maltaf
2016-08-16 03:33
sure
jonathanlevi
2016-08-16 03:33
The top exception (before the unwinding)... starts at the node...
maltaf
2016-08-16 03:33
ok
jonathanlevi
2016-08-16 03:34
The EnrollID is 'DVLA' and the node is trying to get an ECert from the ECA with a username password pair
maltaf
2016-08-16 03:34
ok
jonathanlevi
2016-08-16 03:34
I don't know what your configuration is...
jonathanlevi
2016-08-16 03:34
But the ECA is trying to retrieve a record from its local db, and I believe that this is where everything is breaking...
jonathanlevi
2016-08-16 03:35
... there isn't a record for DVLA (I suspect)
maltaf
2016-08-16 03:35
I am using instructions from here ```https://github.com/IBM-Blockchain/car-lease-demo/blob/master/Documentation/Installation%20Guide.md#deploying-locally111
maltaf
2016-08-16 03:36
I agree, but demo should be creating that record
jonathanlevi
2016-08-16 03:36
So I believe that it's to do with the ECA's configuration...
jonathanlevi
2016-08-16 03:36
Yes, the demo should be creating that record that you are asking for.
maltaf
2016-08-16 03:37
ECA is the membersrvc right?
jonathanlevi
2016-08-16 03:37
Yes, the ECA's (and others') configuration are in fabric/membersrvc/membersrvc.yaml
jonathanlevi
2016-08-16 03:37
` fabric/membersrvc/membersrvc.yaml` for the artists among us (== nicer colors)
jonathanlevi
2016-08-16 03:38
There are both initial users/IDs that are pre-configured, and also the ability to register new ones dynamically
maltaf
2016-08-16 03:39
yes I see that, but DVLA is not one of them
maltaf
2016-08-16 03:41
actually DVLA is in the demo's membersrvc.yaml
maltaf
2016-08-16 03:41
let me try with this one
maltaf
2016-08-16 03:45
yes
jonathanlevi
2016-08-16 03:45
I think we should also slightly change these errors (especially in dev mode)
jonathanlevi
2016-08-16 03:46
[Sorry, a typo]
jonathanlevi
2016-08-16 03:46
To assist us with understanding what's going on.
jonathanlevi
2016-08-16 03:47
BUT the ECA and the TCA are undergoing some more changes... that should make such things easier.
jonathanlevi
2016-08-16 03:48
I'm wondering what other REST (API) calls were expected... after the ECA step. But one thing at a time.
jonathanlevi
2016-08-16 03:48
How does it look over there? :wink:
maltaf
2016-08-16 03:48
It is looking good so far
maltaf
2016-08-16 03:48
no more errors
maltaf
2016-08-16 03:49
somehow I messed up membersrvc.yaml.demo and the actual membersrvc.yaml
maltaf
2016-08-16 03:49
not sure if ```03:48:36.439 [dockercontroller] Start -> ERRO 0fa start-could not start container API error (400): {"message":"starting container with HostConfig was deprecated since v1.10 and removed in v1.12"}``` is really an error
maltaf
2016-08-16 03:51
tried to create scenarios using the demo but it failed with a lot of these errors
maltaf
2016-08-16 03:51
perhaps I should try with the latest code base
maltaf
2016-08-16 03:54
Thanks @jonathanlevi I'll try this with HEAD and see if I can fix these error
maltaf
2016-08-16 03:55

Hey guys, I have a question regarding replay attack protection and I hope that this is the correct channel to post this kind of question:
In section 4.3.3 of the protocol spec there’s a section on replay attack *protection*, where this will be achieved by including a generated nonce together with the user’s Ecert in a transaction.
Yet in section 4.7 it states that “Replay attack *resistance* mechanism is not available”
Is there a difference between “protection” and “resistance”, or is the nonce-method a planned feature that is not yet added? Does that mean that there is currently no way of ensuring replay protection?

Is there a canonical list of environment variables taken by fabric peer and fabric chaincodes?

Is there any examples on User Registration and Security / roles or ecert ? I am trying to understand how can I can use security credentials for user validations with in the chaincode.

@bfuentes: both projects will continue in parallel. hyperledger is meant to be a collection of tools

@bfuentes: Sawtooth does not require an intel processor explicitly, one of the supported consensus mechanisms (PoET) does however

kelly
2016-08-16 16:43
there is another consensus mechanism in the sawtooth repo (quorom) that does not require an intel processor, and is similar to the ripple/stellar consensus
kelly
2016-08-16 16:44
you could also use a traditional BFT-style consensus mechanism as well, although we have not yet released an open source version of that
jenkins
2016-08-16 16:45
Where is the blocksize parameter for hyperledger?
kelly
2016-08-16 16:46
@lbonniot: I agree, we need a public document highlighting the differences, we will work on getting a draft of that up that IBM can comment on
kelly
2016-08-16 16:47
@jenkins: there is no blocksize parameter for HL
ashnur
2016-08-16 16:47
to me it looked that sawtooth is mostly for intel sgx
ashnur
2016-08-16 16:47
and unless i am interested in sgx, there isn't much interesting in sawtooth
jenkins
2016-08-16 16:48
@kelly: So, a block (and its transactions) can be arbitrarily large? Is there no limit except for network constraints?
kelly
2016-08-16 16:48
@jenkins: hyperledger is focused on private deployments, some consensus mechanism used don't even contain 'blocks'
kelly
2016-08-16 16:48
it's a parameter that can be set by those that deploy it though if it is used
kelly
2016-08-16 16:48
@ashnur: sawtooh is focused more on permisionless networks with POET
kelly
2016-08-16 16:49
the PBFT consensus used by fabric doesn't support dynamic addition of peers, or permisionless usages
kelly
2016-08-16 16:49
It also will be difficult for it to scale to hundreds of validators due to the consensus mechanism
ashnur
2016-08-16 16:49
yeah but permissionless is the more common thing anyway
ashnur
2016-08-16 16:49
dynamic addition of peers is something needed though
kelly
2016-08-16 16:49
we agree :slightly_smiling_face:
ashnur
2016-08-16 16:50
so you can't add new peers to a network of fabric peers that run on pbft?
kelly
2016-08-16 16:50
I believe that is correct
kelly
2016-08-16 16:50
though you may want to ask in #
ashnur
2016-08-16 16:50
i was not aware of this
ashnur
2016-08-16 16:50
i will, thank you
kelly
2016-08-16 16:51
also fabric supports execution of arbitrary chain code in docker containers
kelly
2016-08-16 16:51
we have taken an approach where state transitions are explicitly defined
kelly
2016-08-16 16:52
so in some sense fabric is more 'programmable' while sawtooth makes the tradeoff towards security over expressability
ashnur
2016-08-16 16:52
yeah, the arbitrary chaincode is crazy, it was trivial to write some chaincode that goes online, fetches something and does something else based on the response
ashnur
2016-08-16 16:52
i just wish go wouldn't be the only usable language
jenkins
2016-08-16 16:53
@kelly So, it’s conceivable that a single transaction could be hundreds of megabytes, and a resultant block of such transactions could grow to gigabytes? (all arbitrary) This all comes down to application logic?
ashnur
2016-08-16 16:54
@jenkins: but you don't send all the blocks to everyone
ashnur
2016-08-16 16:54
afaik
kelly
2016-08-16 16:54
@jenkins: it's a parameter that is set when you launch the network
jenkins
2016-08-16 16:56
@kelly: Yes, you can set the number of transactions per block. But there doesn’t seem to be a limit on the size of a single transaction?
kelly
2016-08-16 16:56
well fabric doesn't use blocks as far as i know
kelly
2016-08-16 16:57
but yes, for example the deploy transaction on fabric allows you to push a smart contract to the network which could be arbitrarily large i believe
kelly
2016-08-16 16:57
but with both you could enforce a max transaction size or max block size
kelly
2016-08-16 16:57
when i say both I mean sawtooth and fabric
jenkins
2016-08-16 16:58
@kelly: Thanks.

I saw several things were removed from rest_api.json (e.g. port 5000 -> 7050, and deploy function schema was removed)
It seemed the code on gerrit, REST API is now going to be deprecated? is that correct?
So, which direction should I go for, node.js SDK, or direct grpc?

Hey all,
I have a doubt.
Does anyone know how the images for peer and memberservices are built in docker-hub?
They might be using fabric code stored somewhere to build these images, right?
hgabor
2016-08-17 06:20
I guess the images are uploaded from somewhere. Docker-hub works that way
abhishekseth
2016-08-17 06:24
Yeah, but what is that "somewhere”? That is my doubt.
hgabor
2016-08-17 06:26
I guess it is the CI - Jenkins
abhishekseth
2016-08-17 06:27
Actually, the problem is that I am working with docker images for peer and memberservices as published by docker-hub.
Now, If I change something in my local fabric code, how to reflect that change in the containers for peer and memberservices because peer and member services are still using those images published by docker-hub.
abhishekseth
2016-08-17 06:28
Is there any way by which I could reflect my changes in fabric code to the containers for peer and services?
hgabor
2016-08-17 06:31
the images can be built locally. I have never tried using the ones from docker hub. make images builds all the images locally. make peer-image compiles peer image and the ones needed for that
abhishekseth
2016-08-17 06:35
In the documentation for “outside of vagrant” setup, they have pulled images for both the things from docker-hub and I was following that documentation.
By the way, When I run make peer-image, I get the following error
Step 2 : ADD gopath.tar.bz2 $GOPATH/src/github.com/hyperledger/fabric
Error processing tar file(bzip2 data invalid: bad magic value in continuation file):
make: *** [build/image/src/.dummy] Error 1
abhishekseth
2016-08-17 06:37
@hgabor: Do u know how to eliminate this error?
hgabor
2016-08-17 06:39
so are you running it outside of vagrant?
abhishekseth
2016-08-17 06:40
yup.
hgabor
2016-08-17 06:41
and the docs say that you have to download those images from docker-hub, right?
abhishekseth
2016-08-17 06:42
Yeah, they are using that way only.
hgabor
2016-08-17 06:46
are you on mac?
abhishekseth
2016-08-17 06:46
Yes.
hgabor
2016-08-17 06:50
ah cool
hgabor
2016-08-17 06:50
I think @zsolt had a similar problem
hgabor
2016-08-17 06:51
Error processing tar file(bzip2 data invalid: bad magic value in continuation file): <- this is caused by - not 100% sure but - Mac specific tar implementation
hgabor
2016-08-17 06:51
one should install gnu tar maybe
abhishekseth
2016-08-17 06:57
I will ping u again if i have some other issue.@hgabor

I managed to create two validating peers, both running on different virtual boxes. In one of the boxes, I am running membersrvc and started one validating peer. In the other box I started one more validating peer connected to validating peer of the first box and using membersrvc stared in the first box.
First box-
``` CORE_PEER_ID="vp0" CORE_SECURITY_ENABLED=true CORE_SECURITY_PRIVACY=true CORE_PEER_ADDRESSAUTODETECT=false CORE_PEER_PKI_ECA_PADDR=9.161.161.13:50052 CORE_PEER_PKI_TCA_PADDR=9.161.161.13:50052 CORE_PEER_PKI_TLSCA_PADDR=9.161.161.13:50052 CORE_SECURITY_ENROLLID=test_vp0 CORE_SECURITY_ENROLLSECRET=MwYpmSRjupbT peer node start --peer-chaincodedev ```
Second box-
``` CORE_PEER_ID="vp1" CORE_SECURITY_ENABLED=true CORE_SECURITY_PRIVACY=true CORE_PEER_ADDRESSAUTODETECT=true CORE_PEER_DISCOVERY_ROOTNODE=9.161.161.13:30304 CORE_PEER_ADDRESS=9.161.161.13:30304 CORE_PEER_PKI_ECA_PADDR=9.161.161.13:50052 CORE_PEER_PKI_TCA_PADDR=9.161.161.13:50052 CORE_PEER_PKI_TLSCA_PADDR=9.161.161.13:50052 CORE_SECURITY_ENROLLID=test_vp1 CORE_SECURITY_ENROLLSECRET=5wgHK9qqYaPy peer node start --peer-chaincodedev ```
Here 9.161.161.13 is the ip address of the first box.
Once I start the peers, I am seeing the following error
``` 09:21:06.599 [peer] handleChat -> ERRO 266 Error handling message: Peer FSM failed while handling message (DISC_HELLO): current state: created, error: transition canceled with error: Error Verifying signature for received HelloMessage: rpc error: code = 2 desc = "grpc: the client connection is closing"
2016/08/17 09:21:06 grpc: ClientConn.resetTransport failed to create client transport: connection error: desc = "transport: dial tcp 9.161.161.13:30304: getsockopt: connection refused"; Reconnecting to "9.161.161.13:30304" ```
But the command ` peer network list` is able to show the list of peers.
a) Should I be concerned about the error?
b) Is there a way for me to see or verify how the interaction between validating peers happens, I am trying to understand the scenario of more than one validating peer. Any documentation or test cases which I can use? I couldn't find it, hence posting here

@rnemani: As per my info, they are two diff implementations of blockchain, both in incubating stage, both differing in certain concepts. Fabric is a collaboration of a set of companies ( ibm and a set, don't remember other names now :disappointed: ) Sawtooth is also like wise, but its Intel and another set of companies..

here are is a brief snap shot - fabric: written in go, supports permissioned blockchains, goal is high throughput, smart contracts are deployed as individual dockers | sawtooth: written in python, supports permissioned and permissionless usages, goal is high decentralization, smart contracts are defined as 'transaction families'
ashnur
2016-08-17 14:35
what is an individual docker? i am not up to date with the terminology, do you mean that there will be some kind of separate docker image for each chaincode app?
hgabor
2016-08-17 14:40
individual containers, I guess
hgabor
2016-08-17 14:40
one container per chaincode

Hi, I'm talking about fabric project.
I saw several things were removed from rest_api.json (e.g. port 5000 -> 7050, and deploy function schema was removed)
As I checked on the recent code from gerrit, REST API is now going to be deprecated? is that correct?
So, which direction should I go for, node.js SDK, or the direct grpc?
jonathanlevi
2016-08-17 23:48
Membership Services: gRPC
jonathanlevi
2016-08-17 23:49
ClientSDK: NodeJS
jonathanlevi
2016-08-17 23:49
The REST API is still supported, but you might have a lot more control and better granularity as the gRPC API is extended we make progress
jonathanlevi
2016-08-17 23:51
Changing the ports, etc... should not be a big concern (especially if you work within a Vagrant... as these changes have uniformly updated the servers, client, tests... config files, etc.)

jonathanlevi
2016-08-17 23:52
But, of course, a lot depends on what you are trying to do. Some people write their own wrappers or utilize the ClientSDK API... extensively.
jonathanlevi

@stylix ^^^
jonathanlevi
2016-08-17 23:54
(hope this helps)
stylix
2016-08-18 00:05
@jonathanlevi: Thanks for your answer.
BTW, for the REST API, which I extensively used a month or two is now changed someway.
For the port, it's not a big concern.
But another thing, for example, I cannot deploy any chaincode right now, with the error about
"Error unmarshalling chaincode request payload: illegal base64 data at input byte"
This one, as I checked the rest_api.json, the schema about deploy function was removed from ChaincodeInput, and I think this might be removed for some purpose (not a mistake)
---------- rest_api.json ----------------
...
"ChaincodeInput": {
"type": "object",
"properties": {
////////////////// <==== "function" used to be here on github version
"args": {
"type": "array",
"items": {
"type": "string"
},
"description": "Arguments supplied to the Chaincode function."
}
}
},
...
--------------------------------------------------
jonathanlevi
2016-08-18 00:07
Re: the REST API, it wasn't removed - it's still there, but I envision that many of the new features/functionality will be exposed by the gRPC on the Membership Services side and the ClientSDK's end.
jonathanlevi
2016-08-18 00:08
You might also want to follow/watch this item (that was opened this morning):
https://jira.hyperledger.org/browse/FAB-156 `[node-SDK] Create a REST wrapper around SDK`
jonathanlevi
2016-08-18 00:08
Which might be of interest to you, too.
stylix
2016-08-18 00:09
I see.
stylix
2016-08-18 00:10
Actually, I use REST for testing purpose. And probably, for building up client, I might need to follow SDK with Node.js direction.
stylix
2016-08-18 00:11
BTW, is there any concern about running fabric under docker swarm?
stylix
2016-08-18 00:20
Right now, I'm working on running fabric at scale. I somehow managed to set the parameters to each fabric node dynamically. But when I deploy a new chaincode, fabric generally creates a new container to handle a new chaincode separately.
The problem is there, fabric nodes (system chaincode) run under swarm environment. and the user chaincode run outside of swarm. So, no any communication can be done between them.
So, I'm not sure how to deal with this properly.
stylix
2016-08-18 00:22
@jonathanlevi: Since the community seemed to be moved from github, please let me (us) know the right communication channel, for example, to ask some question.
jonathanlevi
2016-08-18 00:25
I think that Slack is fine
jonathanlevi
2016-08-18 00:25
We also have jira.hyperledger.org...
jonathanlevi
2016-08-18 00:25
(which is openly accessible, so you can also open issues there (re: the move from GitHub)
jonathanlevi
2016-08-18 00:26
There are a few current efforts that I know of regarding scale. Nothing confidential, I can share the requirements and I are logged in JIRA.
jonathanlevi
2016-08-18 00:27
One thing is to have multiple Membership Services instances... so that you/the ClientSDK/deployer/etc... don't need to rely only on one instance
jonathanlevi
2016-08-18 00:28
The other is about the collaboration between them (hot-swapping and dynamic addition of nodes/servers)
jonathanlevi
2016-08-18 00:28
I have been playing with some benchmarking WRT generating certs recently. Sometimes working natively on Ubuntu is much faster.
jonathanlevi
2016-08-18 00:29
However, it comes at a cost (say we upgrade to Go1.7 overnight, etc.... having the vbox image is closer to a 'one click deployment')
jonathanlevi
2016-08-18 00:30
As for comm. channels, I would try to pick specific ones. For this kind of general Fabric questions - I'd move to Fabric. There are the # channel, the #, #, #, a few working groups, etc.
stylix
2016-08-18 00:41
@jonathanlevi: Thank you. I'm looking around and following the community.
jonathanlevi

Sure thing. I'd suggest obtaining a cool username at http://identity.linuxfoundation.org/

Hi guys. I’m a little confused about the relationship between Hyperledger, Sawtooth Lake, Fabric, etc. Can someone clarify? Are Sawtooth and Fabric two separate projects under the Hyperledger name? is there a product also by the name of Hyperledger, or is Hyperledger just the name of this initiative?
kelly
2016-08-18 02:16
hey @ac0rn, it's a bit confusing now, but hyperledger is the banner name for this open source group
kelly
2016-08-18 02:16
it used to be the name for a specific product that was acquired by digital asset, but now it's just the name of this open source effort
kelly
2016-08-18 02:16
sawtooth and fabric are two projects under the hyperledger name
jonathanlevi
2016-08-18 02:17
"What is the Hyperledger Project?"
The Hyperledger Project is a collaborative effort created to advance blockchain technology by identifying and addressing important features for a cross-industry open standard for distributed ledgers that can transform the way business transactions are conducted globally.
kelly
2016-08-18 02:17
here is the quick recap I gave above on the differences
kelly
2016-08-18 02:18
I am working on putting together a file that the Intel and Sawtooth teams can add to that will delineate the two projects
kelly
2016-08-18 02:18
here are is a brief snap shot - fabric: written in go, supports permissioned blockchains, goal is high throughput, smart contracts are deployed as individual dockers | sawtooth: written in python, supports permissioned and permissionless usages, goal is high decentralization, smart contracts are defined as 'transaction families'
ac0rn
2016-08-18 02:21
I see, thanks very much @kelly and @jonathanlevi
kelly
2016-08-18 02:23
no problem, let me know if I can help out any other way
jonathanlevi
2016-08-18 02:25
My (formal) answer was taken from https://www.hyperledger.org. I think we should add @kelly's answer in some form to the docs... as this is becoming a FAQ, and many people like to see the global picture with more/enough detail/overview also about each sub-project (e.g., go/Python, philosophy/approach/...)
ac0rn
2016-08-18 02:25
Do either of the projects have true finality? And, also just curious if either of them have checkpoints for the state of the chain?
jonathanlevi
2016-08-18 02:25
That is, I like @kelly's answer more :wink:
jonathanlevi
2016-08-18 02:25
Define finality please?
kelly
2016-08-18 02:25
yes - fabric supports settlement finality with it's pbft algorithim
kelly
2016-08-18 02:26
sawtooth supports probabalistic finality with PoET, and true finality with quorom consensus
kelly
2016-08-18 02:26
I don't believe there is any 'checkpointing' in either, but don't hold me to that
ac0rn
2016-08-18 02:26
Finality as in, once something has been written into the ledger, that it cannot be changed and is done for good. As in, settlement finality.
kelly
2016-08-18 02:26
correct
ac0rn
2016-08-18 02:26
Thanks @kelly
ac0rn
2016-08-18 02:26
:smile:
kelly
2016-08-18 02:27
fabric uses PBFT which provides finality, sawtooth has an implementation of ripple/stellar protocol that provides finality
kelly
2016-08-18 02:28
sawtooth PoET is form of 'nakamoto consensus' so has the same finality characteristics as bitcoin
ac0rn
2016-08-18 02:31
One more question: you mentioned high throughput for Fabric. Is there a comparison for throughput between the two, in tx/s?
jonathanlevi
2016-08-18 02:32
(btw: glad you didn't ask about execution finality)
ac0rn
2016-08-18 02:32
@jonathanlevi: Well, now that you mention it, I am curious :stuck_out_tongue:
jonathanlevi
2016-08-18 02:33
Well, fabric is very permissive in terms of chaincode (the actual code that is executed).
jonathanlevi
2016-08-18 02:34
The design/architecture, or saw, workflow is one where you have parties that authorize actions or certain sets/types of transactions.
jonathanlevi
2016-08-18 02:35
You can still run into weird 'loops', but it is still executed within a docker container.
ac0rn
2016-08-18 02:35
I see
kelly
2016-08-18 02:48
I don't think there is a comparison
kelly
2016-08-18 02:48
I think I saw fabric is targetting 100k/second or something
kelly
2016-08-18 02:48
which seems insane, but what do I know
kelly
2016-08-18 02:52
"The current performance goal for the fabric is to achieve 100,000 transactions per second in a standard production environment of about 15 validating nodes running in close proximity. The team is committed to continuously improving the performance and the scalability of the system."
kelly
2016-08-18 02:54
i read fabric is targeting geographically centralized blockchains (and perhaps administratively centralized)
ac0rn
2016-08-18 03:01
Yeah seems like the goal is 100k tps, and currently users are getting closer to 700 tx/s
ac0rn
2016-08-18 03:02
can’t find anything on the throughput for Sawtooth
jonathanlevi
2016-08-18 03:53
My quick 2 cents on this @ac0rn, is that tx/s by itself is not a super meaningful metric.
jonathanlevi
2016-08-18 03:54
(I believe you know it, from the impression I get by reading the above - I just feel that I should mention it)
jonathanlevi
2016-08-18 03:55
I have ways of stripping down components, working with a super simple chaincode, and playing with the deployment set-up/configuration that will affect 'performance' in many ways.
jonathanlevi
2016-08-18 03:55
I do think though, in that respect, that we should start assembling a set of 'tests'
jonathanlevi
2016-08-18 03:56
We need a set of 'geekbench'-like tests... or so.
jonathanlevi
2016-08-18 03:56
Because there are many factors there.... and the variance in results is huge.
stylix
2016-08-18 04:00
Actually, I also did some experiment on the throughput. And I agreed about several factors might be involved.
BTW, I still not be able to reach ~100k tps.
I deployed 15-20 validating nodes on 15-20 VMs, and I can reach only about 800 tps.
Then I tested with 4 validating nodes on 4 physical servers, so I reach about 1200 tps.
These test were done with a very simple chaincode, by doing just val++ on the state, and transactions were sent through the REST API.
jonathanlevi
2016-08-18 04:00
OK, let's not `compare sizes`... but :wink:
jonathanlevi
2016-08-18 04:01
I can't reach even 50K tx/s... but I can show you some set ups that can reach a *stable* 2K/s
stylix
2016-08-18 04:02
Umm, that was interesting.
jonathanlevi
2016-08-18 04:09
I know, but again, I was focusing on a particular component.... (TCert generation... in case you wondered), and the invoke()d code is super simple, etc.
jonathanlevi
2016-08-18 04:10
I believe we can get 5 figures... in some deployments too (again, subject to hardware, etc.)... I'm talking about a modest, local PC, etc.
jonathanlevi
2016-08-18 04:11
If you either 1) have more patient, or, 2) want to help with some of these...
jonathanlevi
2016-08-18 04:11
We are going to have some nice tasks in that respect.

ashishkel
2016-08-18 04:26
does this mean that we have to use NodeJS to deploy the custom chaincode from now onwards?
bgorman
2016-08-18 05:00
@ashishkel you can use any of the three interfaces: the Node.js SDK, the CLI or the REST interface
bgorman
2016-08-18 05:00
the REST interface is a bit weird at the moment though
ashishkel
2016-08-18 05:02
@bgorman weird, in the sense ? doesn't work as intended?
bgorman
2016-08-18 05:02
the syntax has changed as of last week, I'm working to restore it
bgorman
2016-08-18 05:03
you can see an example here: https://gerrit.hyperledger.org/r/#/c/499/1/docs/API/AttributesUsage.md
bgorman
2016-08-18 05:03
Function got moved into the args array, all args also need to be base64 encoded at the moment
ashishkel
2016-08-18 05:06
ohkay, thts why stylix mentioned that function is missing.
ashishkel
2016-08-18 05:06
and u mentioned u are gonna restore.
ashishkel
2016-08-18 05:06
so its gonna be back, the way it was. rite? in some days.. ?
ashishkel
2016-08-18 05:09
args in base64 encoded format. that is still okay to live with. One can claim that we should take care of the data security over the n/w a bit.
bgorman
2016-08-18 05:09
sorry, what does base64 have to do with security?
ashishkel
2016-08-18 05:09
i mean its better than sending the bare unencoded data along the network.
bgorman
2016-08-18 05:10
no.... it is no better than unencoded data
bgorman
2016-08-18 05:10
encoding != encryption
bgorman
2016-08-18 05:10
anyone can decode base64 encoded data
ashishkel
2016-08-18 05:10
ohkay... i get it. cos its straightforward decoding
ashishkel
2016-08-18 05:10
yea, i get it
bgorman
2016-08-18 05:10
there is no secret :slightly_smiling_face:
ashishkel
2016-08-18 05:11
:slightly_smiling_face: rite :slightly_smiling_face:
bgorman
2016-08-18 05:15
but yes, I'm trying to change the REST API to take either form of the Function argument, and not to need base64 encoding
ashishkel
2016-08-18 05:17
Thank god. Cos i have a lot riding on this REST API now. - because it makes straightforward decoupled interfacing possible with Fabric
ashishkel
2016-08-18 05:17
and with node.js, i dont know honestly - a client program -> ?? -> Node.js -> Fabric. Dont know how to make this work
bgorman
2016-08-18 05:18
I guess you could write a REST API for the Node.js SDK... or maybe it has one already, I haven't used it
bgorman
2016-08-18 05:19
hopefully you don't need to though
bgorman
2016-08-18 05:19
I just need to figure out why the unit test fail on my code :disappointed:

2016-08-18 10:14
ChaincodeInput looks like { Args :: [][]byte } note that function was removed as it is the 0. argument of Args
REST API needs base64 strings in a list to be able to unmarshal that as [][]byte
hgabor
2016-08-18 10:15
but this will "fix it", so you can use it with strings https://gerrit.hyperledger.org/r/#/c/531/

the docker hub pushing thing is done by some automated Jenkins job, I guess

hmm to be honest I cant really answer your question. :S I just suppose that the change is already on docker hub
venkat
2016-08-18 10:39
no problem. I think the base64 thing should be optional and may be declared through an attribute - may be some content-type etc.?
hgabor
2016-08-18 10:40
that base64 thing is caused by the json encoder/decoder of go. it cannot be made optional, it can only be workarounded. and https://gerrit.hyperledger.org/r/#/c/531/ is doing that. :slightly_smiling_face:

All go examples in : fabric/docs/setup/chaincode-setup,md ...
hgabor
2016-08-18 10:58
@venkat @trichalo all the docs from this changeset: https://gerrit.hyperledger.org/r/#/c/499/ those are the same docs you have in your repo but they are updated which means they contain examples for the new REST API where base64 Args parameter is needed. but as I said that changeset won't make it into the repo (that is why I am giving you that link) because it will be deprecated in some days.
hgabor
2016-08-18 10:59
do you get it? :slightly_smiling_face:
trichalo
2016-08-18 11:00
Which repo ? Git or Gerrit/Main
venkat
2016-08-18 11:00
@hgabor - we are fabric users. Not fabric developers. The only documentation we have is from github wiki
trichalo
2016-08-18 11:00
guhub rather
trichalo
2016-08-18 11:00
or github :wink: ....
hgabor
2016-08-18 11:01
yes but you can open the link and see these docs there, right? :slightly_smiling_face: I can't merge it myself for you
hgabor
2016-08-18 11:01
no other way for me to help you, I can only link those docs

Sure - now after you have given the links, I can see and fix. But before that I had no clue about what was going on.
trichalo
2016-08-18 11:02
that is the new cli ....line
hgabor
2016-08-18 11:02
yes that is the CLI
trichalo
2016-08-18 11:02
ah
trichalo

hgabor
2016-08-18 11:02
@venkat @trichalo sorry for that
trichalo
2016-08-18 11:04
@hgabor: No worries... I'm sure I'll be up and running now...
hgabor
2016-08-18 11:04
I have updated the docs last week but the other devs said we don't want to merge it
venkat
2016-08-18 11:04
whoever tries to use the latest fabric image from docker hub will run in to this issue
venkat
2016-08-18 11:05
no issues - I'm good now.
hgabor
2016-08-18 11:05
yes I know. we have two ways to solve this: 1) merge those docs 2) workaround rest api to use string as it used to https://gerrit.hyperledger.org/r/#/c/531/
hgabor
2016-08-18 11:06
okay you are right this cannot go on this way. I will try to contact other devs to help and solve this problem
hgabor
2016-08-18 11:09
@trichalo: is it working?
trichalo
2016-08-18 11:10

venkat
2016-08-18 11:14
@hgabor - can you please help in finding a recent fabric peer image tag that doesn't require base64?
hgabor
2016-08-18 11:14
yes
venkat
2016-08-18 11:14
Thanks!!
trichalo
2016-08-18 11:14
I also noticed some doc errors : COREPEERADDRESS should be CORE_PEER_ADDRESS ...
trichalo
2016-08-18 11:15
Same doc page...
hgabor
2016-08-18 11:15
are there more than one fabric images on dockerhub?
ashnur
2016-08-18 11:15
yeah
ashnur
2016-08-18 11:15
but there is only one that's good, and you can find it easily which one because the others are either old or the dockerfile says that it's deprecated
hgabor
2016-08-18 11:16
@ashnur by being good, do you mean it requires no b64?
ashnur
2016-08-18 11:17
i didn't mean that.
ashnur
2016-08-18 11:17
i was thinking of this one

2016-08-18 11:21
But the chaincode exec did not fail
hgabor
2016-08-18 11:21
@trichalo do you mean that the base64 part works? :slightly_smiling_face:
trichalo
2016-08-18 11:21
yes
trichalo
2016-08-18 11:21
I think... no error but tx not yet processed.
hgabor
2016-08-18 11:22
sorry but in consensus internal issues I cannot help
hgabor
2016-08-18 11:22
do you use pbft?
hgabor
2016-08-18 11:24
@trichalo
trichalo
2016-08-18 11:24
yes
hgabor
2016-08-18 11:25
could you please try it with noop consensus? I know that it is not interesting at all for users but maybe that works and we can be sure that it is a pbft issue :slightly_smiling_face:

Do Fabric and Sawtooth use hash pointers of the previous block the same way Bitcoin does?
middleton
2016-08-18 13:46
@ac0rn Sawtooth uses a previous block ID in the block header.

@middleton uploaded a file: https://hyperledgerproject.slack.com/files/middleton/F22JW9890/-.txt

Hi all. Hyperledger looks like the right blockchain for my new startup. Thanks for all your hard work. We need to be live in the next few months. *When will hyperledger be production ready?*
Also, IBM has a hosted hyperledger. Do they deploy from http://gerrit.hyperledger.org? How long is the delay before something hitting the master branch there to when it is deployed in IBM’s hyperledger cloud?

hi i am new here can anybody help me understand the concept of consensus in hyper ledger and why it is used
bithin
2016-08-19 06:16
hey ranjan008
bithin
2016-08-19 06:17
you need to know the concept of blockchain first, so may be you should read about it first
bithin
2016-08-19 06:17
@ranjan008 ^^
ranjan008
2016-08-19 06:18
i am not new to blockchain concept just new to hyperledger
bithin
2016-08-19 06:19
So you know how concensus work in blockchain right?
bithin
2016-08-19 06:20
you now about permissionless and permissioned blockchain?
ranjan008
2016-08-19 06:20
yes
bithin
2016-08-19 06:20
what is it?
bithin
2016-08-19 06:20
can you explain
ranjan008
2016-08-19 06:22
basically permissionless blockchain is public one where you dont need any permission to connect to it while the other is just opposite
bithin
2016-08-19 06:22
can you be more specific?
ranjan008
2016-08-19 06:25
in public blockchain anybody can connect with the chain and implement their own node and do transactions which will again be visible to everyone connected while in private one to connect to the chain you should gain permission from the node which you want to connect then only you will be able to join the network
bithin
2016-08-19 06:25
Ok
bithin
2016-08-19 06:27
So in permissionless blockchain, that is being used by Bitcoin uses a consensus algorithm called as Proof-of-Work whereas in Permissioned Blockchain we usually use concensus algorithm such as PBFT(Practical Byzatine Fault Tolerence).
bithin
2016-08-19 06:27
In case of PoW, the nodes which participate in concensus need not trust each other
bithin
2016-08-19 06:27
so as the case in bitcoin
bithin
2016-08-19 06:28
if you want to add a node to the blockchain, the node which solves a crypto puzzle get the chance to add a new node to the blockchain
bithin
2016-08-19 06:29
but in PBFT, each node participating in the concensus process
bithin
2016-08-19 06:30
so concensus algorithms is basically used by a qurom of node to decide among themselve abt who is going to make change to the blockchain next
bithin
2016-08-19 06:31
In hyperledger, there are different project(you can watch the introductory video in youtube) fabric uses PBFT and also sawtooth lake which have PoEF and quroum voting
bithin
2016-08-19 06:31
this is very abstract explaination and based on my understanding
bithin
2016-08-19 06:31
hope it is clear
ranjan008
2016-08-19 06:31
thanks
bithin
2016-08-19 06:32
You are welcome
ranjan008
2016-08-19 06:33
one more thing if i am deploying a chaincode is it mandatory to put the chaincode in github or we can do it through local path also
bithin
2016-08-19 06:36
I have not worked with chaincode, focusing more on sawtooth :slightly_smiling_face:
bithin
2016-08-19 06:37
may be someone else in the group can help
ranjan008
2016-08-19 06:37
its k anyway thanks for the help
jcarrivick
2016-08-19 06:37
@ranjan008 I believe you can using the NodeJS SDK but I have not had any experience using it myself
ranjan008
2016-08-19 06:38
i am using rest api call but its not taking but github urls its taking
jcarrivick
2016-08-19 06:39
Using the REST api you definitely can only deploy public projects from github
ranjan008
2016-08-19 06:39
in private network also
ranjan008
2016-08-19 06:40
?
jcarrivick
2016-08-19 06:40
it essentially does a `go get <path>` to build the chaincode which requires a public git repository
jcarrivick
2016-08-19 06:40
yes, even in a private network
jcarrivick
2016-08-19 06:40
If you want to deploy private code you will need to use the SDK, however I have not had any experience using it myself unfortunately.
ranjan008
2016-08-19 06:41
thank you for the help i will try with github @jcarrivick

Hi, I just wanted to understand what all data is logged on the blockchain as a part of a transaction, i understand that it contains hash of the delta (changes made in world state as part of transactions in a block). Can we back trace values of a variable in the world state, so as to get the changes done to it historically, including time at which such changes happened. Hope my question is clear.
puneet-itpc
2016-08-19 09:33
In case we cannot back trace the values as it is all stored in a hash which cannot be decrypted, what are other methods through which we can record this transition of state variable values data, so as to be immutable.
simon
2016-08-19 09:35
puneet-itpc: maintain a log?
simon
2016-08-19 09:35
puneet-itpc: what's your objective?
puneet-itpc
2016-08-19 09:35
how, in a world state itself
simon
2016-08-19 09:35
imagine you design a database
puneet-itpc
2016-08-19 09:36
I am trying to create an auditable record of ownership changes to an asset
puneet-itpc
2016-08-19 09:37
I just want to make sure that we cannot actually do this by decrypting the delta hash in the block
simon
2016-08-19 09:37
in what way do you want to audit it? off-line, or within the chaincode
puneet-itpc
2016-08-19 09:37
within the chaincode
simon
2016-08-19 09:37
then you need to keep the information in the world state
puneet-itpc
2016-08-19 09:38
Is there a limit to memory of world state
simon
2016-08-19 09:38
i don't think that there is currently a quota
puneet-itpc
2016-08-19 09:38
because I guess that will fill up fast if there is
puneet-itpc
2016-08-19 09:38
ok
simon
2016-08-19 09:38
of course physically there is a limit
puneet-itpc
2016-08-19 09:38
yes
simon
2016-08-19 09:39
and make sure that you're only adding to your state, and not change it completely every time
puneet-itpc
2016-08-19 09:39
yes, you mean I just append and not overwrite the rows
simon
2016-08-19 09:39
yes
puneet-itpc
2016-08-19 09:39

@vijayr24 in latest fabric's version the format was changed. Function name should be in Args and all parameters should be base64 encoded. The arguments for deploy command will look like ""args":['aW5pdA==', 'YQ==', 'MTAwMA==', 'Yg==', 'MjAwMA==']"

The binary peer file's location is ./build/bin/ folder. For your configuration the full path is "/opt/gopath/src/github.com/hyperledger/fabric/build/bin/".
remove it and make peer, if you want re-make it.

Hi - I have a question about an exact number of projects running under Hyperledger umbrella right now. There is Fabric (IBM, Digital Assets, DTCC...) and Sawtooth Lake (Intel). Recently, a block explorer from DTCC was introduced. However, back in March various crypto news sources informed that JPMorgan opened a new blockchain project called "Juno" and that it will be managed through Hyperledger. Since there is no factual reference to this on http://hyperledger.org I assume this either did not come to fruition or news outlets were misinformed.

@balakrishna instead of "-n mycc" you should provide real chaincode ID which was generated by "deploy" command

Folks, the docs for example02 chaincode seem to be way out of sync with the latest fabric shim code. Can someone look at this?
venkat
2016-08-22 09:52
This is very critical for us as we need a stable shim interface for our chaincode to interact with
venkat
2016-08-22 09:54
We need a really working example that can show us chaincode deployment and using the chaincode through REST API. Currently, both of these basic features are broken, if we follow the docs for the examples.

in addition, it seems there are changes to the ctorMsg args (method name is added), and base64 is enforced.
venkat
2016-08-22 10:30
We are fabric users and not fabric devs. My expectation is, we can do a standard setup by following the guidelines from the Chaincode Setup page. And then focus on writing chaincodes, deploy them and test. May be I'm wishing for too much?

And the Chaincode:

It worked for some time ( at least an hour) before no results being returned. The logs on the peer do not reveal anything for us to figure out the issue. Could you please help us on this issue. We have notice the same last week and therefore, we reset the chaincode and redeployed it today.

Am I right to ask sawtooth issues? I just followed tutorial http://intelledger.github.io/tutorial.html . After ./bin/txnvalidator -v --http 8800 --config /project/sawtooth-docs/source/tutorial/txnvalidator.js command there is an issue that No module named sawtooth.config from File "/project/sawtooth-validator/txnmain/validator_cli.py", line 25
jzou3700
2016-08-23 02:48
The python code is that "from sawtooth.config" import ArgparseOptionsConfig

2016-08-23 02:51
Hi @jzou3700 . We just restructured the repos this past weekend.
middleton
2016-08-23 02:52
Whereas there was a separate repo for sawtooth-validator and so forth, now everything is in sawtooth-core. The directory structure under sawtooth-core maps pretty closely to the old repo structure ... e.g. sawtooth-validator is in sawtooth-core/validator etc.
middleton
2016-08-23 02:54
That json configuration file will be in /sawtooth-core/docs/source/tutorial
middleton
2016-08-23 02:55
and the config module in the error is here: /sawtooth-core/core/sawtooth
kelly
2016-08-23 03:09
@middleton also the -http command is deprecated now too right?
middleton
2016-08-23 03:11

I have few experience of python. I suppose the sawtooth.config should be a directory structure like config/sawtooth. After searching sawtooth with find , no config/sawtooth directory exists

ok, let's take it over to the #sawtooth channel.

2016-08-23 09:57
or whatever the current suggested version is.
cbf
2016-08-23 10:00
@ashnur it is baked into the build. however, when we transitioned to Gerrit, we also had to change how the docs are hosted. Previously, they were hosted by http://redthedocs.com servers, but they don’t support Gerrit, only GH with webhooks. We currently have an ask in to spin up a server to host all of our docs (fabric and sawtooth) and I hope to have that operational in a couple days. IN the interim, you can use https://cbf-fabric-docs.readthedocs.io/
cbf
2016-08-23 10:00
I maintain a fork that runs the readthedocs build.
ashnur
2016-08-23 10:02
I see, just because all the http://github.com mentions are really confusing imho
cbf
2016-08-23 10:23
@ashnur we welcome help in improving the docs. Yes, there are some references still because we only recently transitioned to Gerrit. If you see things needing to be changed, please either open a JIRA issue or send in a patch. Thanks!

Hi, while doing vagrant up with latest hyperledger fabric source from gerrit, it is exiting with result below
==> default: make: ***

The SSH command responded with a non-zero exit status. Vagrant

@stylix uploaded a file: https://hyperledgerproject.slack.com/files/stylix/F24Q1PEFR/discovery_list.png and commented: Hi,
I managed to run Hyperledger/Fabric at scale with docker swarm on the cluster.
In this scenario, the new node can join the network when we scale up,
and some will leave when we scale down.
---- Thing is that ----
The running nodes have it list of "Discovery nodes", which is never be updated (if I'm right).
Since the peer know the full list, then it try to communicate to the other nodes on the list, at which some may not come back anymore.
Even this shows the annoying ERROR on the log, but it has no problem with any later invokes.
---- Questions ----
Should we still keep the full discovery list?
Should we update the list for keeping only it's active member?
yacovm
2016-08-25 07:22
@stylix when peers emerge they use the root peer to know which node to connect to
yacovm
2016-08-25 07:23
the root peer can be a list of peers, not only a single one
yacovm
2016-08-25 07:23
I mean, I think, unless it has changed and i don't know
yacovm
2016-08-25 07:23
in fabric 0.5 all validating peers should connect to all because they all participate in concensus
stylix
2016-08-25 07:41
@yacovm well, I don't know either it has changed or not.
However, I set the CORE_PEER_DISCOVERY_ROOTNODE dynamically depends on the current active nodes.
BTW, my question, I mean, the running node (that's still alive) has a list of discovery nodes then keep growing and synchronizing the list between running nodes.
In the situation that, some node down (they may come back or maybe down forever),
should we still keep its IP address in the list of discovery node?
Since we will always have the annoying ERROR appears when we cannot connect to it.
Example
1. Start all nodes
vp0, vp1, vp2, vp3
Discovery know about: vp0, vp1, vp2, vp3
Trying to connect: vp0, vp1, vp2, vp3 ==> All OK
2. Join 1 new node
vp0, vp1, vp2, vp3 <== vp4 (join)
Discovery know about: vp0, vp1, vp2, vp3, vp4
Trying to connect: vp0, vp1, vp2, vp3, vp4 ==> All OK
3. Drop vp2
vp0, vp1, vp3, vp4 ==> vp2 (drop)
Discovery know about: vp0, vp1, vp2, vp3, vp4
Trying to connect: vp0, vp1, vp2, vp3, vp4 ==> vp2 ERROR
From the example, you see that connecting to vp2 is not possible, and cause the error message.
So, I'm not sure should vp2 IP be deleted from discovery node list after some timeout?
yacovm
2016-08-25 07:42
I think you can set that env var to be a list, e.g peer1,peer2,peer3
yacovm
2016-08-25 07:42
and yeah of course you'll have an error...
stylix
2016-08-25 07:43
Yes, I meant, I set CORE_PEER_DISCOVERY_ROOTNODE dynamically as a list of IP:PORT,IP:PORT,...
yacovm
2016-08-25 07:43
how can you set it dynamically while a peer is running?
yacovm
2016-08-25 07:43
I mean, you could use gdb to change the env var, but i think the code caches it. I remember there was a configuration cache
stylix
2016-08-25 07:45
Before running "peer node start" I run my script to set the ENV dynamically for each peer
yacovm
2016-08-25 07:45
oh
yacovm
2016-08-25 07:45
then it's only for that peer
stylix
2016-08-25 07:46
it means, each peer will be feed ENV to the wider root node as possible
yacovm
2016-08-25 07:46
well, what are you asking basically- whether should the peer "forget" about dead peer(s)?
stylix
2016-08-25 07:46
yes, right
yacovm
2016-08-25 07:47
I don't think it's too "bad", I'll tell you why- the communication uses gRPC streams
yacovm
2016-08-25 07:47
which means, it's asynchronous
yacovm
2016-08-25 07:47
you put the data in the TCP buffer and don't wait for an application-level ACK
yacovm
2016-08-25 07:47
if the system "knows" there is no one in the other side, it'll simply emit an error
yacovm
2016-08-25 07:47
(the method call, that is)
stylix
2016-08-25 07:50
But, will it keeps this dead peer forever?
I meant, maybe it's annoying with the ERROR message.
And we might not avoid this message with CORE_LOGGING_LEVEL=INFO.
yacovm
2016-08-25 07:52
i know. I don't know if it's that important. version 0.5 isn't supposed to be used in a highly dynamic environment. The next architecture will deal with this much better, however i'm pretty sure there will still be ERROR messages
stylix
2016-08-25 07:56
Well, I think this kind of connection ERROR is somehow important to know.
But, the system should not keep it as the ERROR for long.
E.g. delete those peers from the list after timeout.
stylix
2016-08-25 07:56
it just my random idea.
yacovm
2016-08-25 07:56
yeah, like i said- in the next architecture they'll get deleted after a period
stylix
2016-08-25 07:56
BTW, thank for letting me know, a bit insight.
yacovm
2016-08-25 07:57
well, at least the part that disseminates messages to most of the peers

has anyone had any issue like this before?
stylix
2016-08-25 08:05
BTW, I'm now working in between Docker swarm and Fabric.
I made some tools to generate parameter dynamically for each fabric node under swarm.
The solution goes well under cluster to make fabric lives under swarm, and possible to scale up/down on the fly.
But, I somehow hope we will have this thing works out-of-the-box.
Let me know, if my configuration needed to be explained.
stylix
2016-08-25 08:08
@szlaci83 Do you mount the /var/hyperledger/production to your host?
Please make sure you delete it well, all containers, and database.
stylix
2016-08-25 08:09
It usually happens if you do not clean it perfectly.
stylix
2016-08-25 08:10
Especially docker, you better use 'docker ps -a' to see your containers
szlaci83
2016-08-25 08:11
in my script i do rm -rf /var/hyperledger/production first than delete the containers..... that might be the issue....
szlaci83
2016-08-25 08:13
@stylix thanks for the idea.... can i disturb you later with my network setup issues? it seems you are good at it :slightly_smiling_face:
stylix
2016-08-25 08:17
You better do 'docker rm your_container' before doing 'rf -rm ...'
Then the database will not get locked by the container.
szlaci83
2016-08-25 08:17
yepp now i see
szlaci83
2016-08-25 08:32
@stylix it didnt solve it, but i realised that i have modified a running peer once and I didnt delete the database directory in the peer and commited it like that... :smile:
stylix
2016-08-25 08:57
I see, that happens to me, sometime. when I have lot of thing to do...

That would probably depend on a lot of things. I'd recommend taking a look at the docs and seeing how it matches your interest. For Sawtooth there are some tutorials to help you get started.
sukrith
2016-08-25 18:34

middleton
2016-08-25 18:35
There are 2 main difference that come to mind..
consensus:
middleton
2016-08-25 18:35
sawtooth= PoET; Fabric=Pbft variant
middleton
2016-08-25 18:35
Transaction Logic:
middleton
2016-08-25 18:36
Sawtooth= Transaction families; Fabric = Chain code
middleton
2016-08-25 18:36
PoET is a green form of Random Leader Election (c.f. Proof of Work)
middleton
2016-08-25 18:37
Fabric consensus is a variant of PBFT
middleton
2016-08-25 18:37
Transaction Familes are transaction logic deployed on the validator.
middleton
2016-08-25 18:38
Chain code is transaction logic deploy in dockers via Ledger transactions.
sukrith
2016-08-25 18:39
hmm i see thanks for the summary. I will start reading the 2 wikis!

hi im trying to run 4 peers with pbft using v0.5 of fabric and i get this error after deploying chaincode:
^[[36m02:27:24.930 [consensus/obcpbft] unicastOne -> DEBU 5cf^[[0m could not send to replica 1: Message handler not found for receiver vp1
^[[36m02:27:24.930 [consensus/obcpbft] unicastOne -> DEBU 5ce^[[0m could not send to replica 3: Message handler not found for receiver vp3
^[[36m02:27:24.931 [consensus/obcpbft] unicastOne -> DEBU 5d0^[[0m could not send to replica 2: Message handler not found for receiver vp2
0
Replica 0 found incorrect signature in view-change message: Could not verify message from vp0
garisingh
2016-08-28 09:52
@szlaci83 - seems like vp0 was not able to connect to the 3 other peers (I think)

@garisingh thanks, but I dont get the reason, as it was fine without pbft(security, privacy enabled)
garisingh
2016-08-28 19:29
you mean running 4 peers with security and privacy but no PBFT?
garisingh
2016-08-28 19:29
in NOOPS mode you won't get an error if it can't send to the other peers
szlaci83
2016-08-28 19:44
@garisingh yes, but in noops mode it sent the deployed chaincode to others -> I had 4 docker containers for the peers + 4 for the chaincode, so i assumed it could communicate to others
szlaci83
2016-08-28 20:16
@garisingh Is my logic right?
garisingh
2016-08-28 20:18
yeah - seems like it did work with NOOPS.
garisingh
2016-08-28 20:18
did you happen to set `CORE_PEER_ID=vp0` , `CORE_PEER_ID=vp1` , `CORE_PEER_ID=vp2`, `CORE_PEER_ID=vp3` when using PBFT?
szlaci83
2016-08-28 20:22
nope

2016-08-28 20:23
does it help? :smile:

szlaci83
2016-08-28 20:23
(on 2 machines )
garisingh
2016-08-28 20:37
yeah - PBFT has a fixed set of IDs - so you need to set the ID for each peer you run and they need to be in the form `vpX` - hence `vp0,vp1,vp2,vp3` etc
garisingh
2016-08-28 20:39

@garisingh I have just checked actually its not missing, its just :CORE_PEER_ID=test_vp0
garisingh
2016-08-28 21:14
Hmmm - I think it has to be vp0,vp1,etc but I might be wrong

Hi, quick question around deployment model. I understand that we have a deployment model of - Cloud Hosted One Network. And by this it means that - cloud vendor will own physical resources but Participant will control Computing resources, making it decentralized within a centralized environment. Please can someone explain this in bit detail? (I am confused because once I am on cloud, cloud vendor owns/manage/controls hardware as well computing resources. In case of Blockchain, what is changing when we go with cloud hosting?)

In Fabric Protocol Specification, I found following explanation: “This implementation of membership services provides the following basic functionality: there is no expiration/revocation of ECerts;”. While I also find some difference explanation in this doc “ECert Expiration: Enrollment certificates have different validity period length(s) than those in transaction certificates.”, “Enrollment Certificates (ECerts) ECerts are long-term certificates.”
My question is whether ECert will expire and how can I configure it ? I’m a little confused

Hi, I'm using PBFT. I somehow manage to run Fabric on Docker swarm, means, I can scale up/down nodes on the fly.
BTW, I have a question. Is it possible to join a new VP after the existing nodes already have blocks?
E.g.
1. I start with 4 VPs (vp1, vp2, vp3, vp4).
2. Deploy chaincode, all 4 VPs create a new image and run create a new chaincode attaches to itself.
3. Pump transactions, all 4 VPs update its chain.
4. Join a new node as vp5, all existing 4 VPs know the newly join node, discovery list got updated, all 5 VPs connection seemed to be fine.
**Problem**
All new transactions, will not affect to the vp5, but only old 4VPs. Means, I can also send transaction to vp5, but it will pass all the transaction to the rest 4 VPs.

@cbf That doc view is a lot better than what I was perusing last week. I went back to http://hyperledger.org to figure out how a new person to the project could find that spot. It was not simple. It might help if the http://hyperledger.org link to Github pointed to the Hyperledger repo's readme.md which is a decent index. I'm sorry if this is not the right place for such a suggestion. Just lmk where it should go.

newbie question - if there is no mining in fabric, how is the immutability guaranteed? Isn't is easy for an "authoritative" peer to republish the entire blockchain?
garisingh
2016-08-29 17:35
the transaction log (ledger) is immutable - it is a "hash chain" of blocks which contain batches transactions (e.g. invoke chaincode xyz with parameters 1,2,3) and a hash of the world state at the time the block was created.
venkat
2016-08-29 17:41
so, there is only one main chain - no forked chains as in bitcoin blockchain?
venkat
2016-08-29 17:44
like in serializable consistency - all transactions are strictly ordered.?
garisingh
2016-08-29 17:47
@venkat - correct - it is a permissioned blockchain which currently used PBFT for consensus. One of the requirements of a permissioned network and for Paxos-like algorithms such as PBFT is that you must know all of the participants in the network. So when you start the fabric using PBFT, the default setting is that there will be 4 validators that will be part of the network. The network won't start until at least 3 of them are active and connected to each other. They transactions are indeed ordered
venkat
2016-08-29 17:48
Is there a possibility that 2 txns could be recieved almost at the same time by two validating peers?
garisingh
2016-08-29 17:49
when a transaction is submitted to a peer from a client, that peer then submits the transactions for consensus which then orders the transactions
garisingh
2016-08-29 17:50
all validating nodes then agree on the order of transactions and then that "batch" is sent to the peers who then execute the transactions in order
garisingh
2016-08-29 17:52
(there's lots more low-level detail, but hopefully this helps clarify / explain the basics)
venkat
2016-08-29 17:54
for example, two different clients submit transactions based on what they saw as current state (which is the same as seen by both), then the results after the transactions executed, could be somewhat unexpected by he clients?
venkat
2016-08-29 17:54
or sometimes those txns could be invalid (because the state no longer what the clients saw)
venkat
2016-08-29 17:56
sorry - ignore my last question.
venkat
2016-08-29 18:05

@garisingh : I was curious what would happen if we have a federation/consortium network deployed in two sites, each having 4 approval peers, and suddenly a connection between the two would be cut. How does PBFT behave in split brain scenario and afterwards, when a reconciliation has to happen?

hi am new to hyperledger world. Could you please help me to fix the below issue that am facing while setting up the development environment
shireesh18
2016-08-31 13:59
Am following this link https://github.com/hyperledger/fabric to set up development environment on my machine. I am using Vagrant and Oracle virtual box to deploy the fabric code onto the virtual machine(ubuntu) . I could able to clone the code from the gerrit repository and bring up the virual box but the code has not been deployed or build on the virtual machine. It keeps giving me the below error.
How can I update protobuf on ubuntu, does the update still help ? I have read somewhere that even the latest protobuf version supports only proto2. Plz help to overcome this issue
==> default: Unrecognized syntax identifier "proto3". This parser only recognizes "proto2".
==> default: make: *** [vendor/github.com/golang/protobuf/jsonpb/jsonpb_test_proto/more_test_objects.pb.go] Error 1
The SSH command responded with a non-zero exit status. Vagrant
assumes that this means the command failed. The output for this command
should be in the log above. Please read the output to determine what
went wrong.

@shireesh18 its unclear how this is happening, but it appears you have protoc v2 installed when we require protoc v3
ghaskins
2016-08-31 14:21
this should have been managed for you in vagrant though
ghaskins
2016-08-31 14:22
can you clarify: are you using _our_ vagrant, or did you roll one yourself?

@ghaskins, @shireesh18: I had the same issues yesterday using ‘your’ - don’t mean to point fingers - vagrant.
I was told there was bad fix included in the current fabric; but haven’t received any further information
ghaskins
2016-08-31 14:30
@thomas.marckx you are saying you checked out fabric.git, cd devenv, vagrant up, and you saw that proto3 error?
ghaskins
2016-08-31 14:31
vagrant was broken between Friday and Monday, but at no time was I aware of a problem that would have resulted in proto2 getting installed
shireesh18
2016-08-31 14:31
@ghaskins , I have downloaded from the link https://www.vagrantup.com/ that has been mentioned in the docs
shireesh18
2016-08-31 14:33
I have clone the code using this command it clone && scp -p -P 29418 :hooks/commit-msg fabric/.git/hooks/
shireesh18
2016-08-31 14:33
git clone && scp -p -P 29418 :hooks/commit-msg fabric/.git/hooks/
thomas.marckx
2016-08-31 14:34
@ghaskins I followed these steps (http://hyperledger-fabric.readthedocs.io/en/latest/dev-setup/devenv/)
I was able to access the VM via vagrant ssh, but received the proto3-error while trying `make peer`
ghaskins
2016-08-31 14:34
interesting…not sure how that could have happened
shireesh18
2016-08-31 14:34
@ghaskins @thomas Yes I too have followed the steps from that link
ghaskins
2016-08-31 14:34
ok, good to know
thomas.marckx
2016-08-31 14:36
I’ve continued using deployments on docker, but it would be nice to boot a peer locally. Please keep in touch if you’d find a solution
shireesh18
2016-08-31 14:39
@thomas.marckx , could you ping me the documentation if any on how to deploy on docker . Thanks in advance

@shireesh18 its not clear what SSH host you are trying to connect to, but it seems like standard ssh type problems
shireesh18
2016-08-31 14:50
@ghaskins , let me know if this helps Permanently added '[http://gerrit.hyperledger.org]:29418,[198.145.29.90]:29418' (RSA) to the list of known hosts
ghaskins

ghaskins
2016-08-31 14:50
where are you running this, where are you cloning fabric from, etc
shireesh18

@ghaskins am following this link http://hyperledger-fabric.readthedocs.io/en/latest/dev-setup/devenv/
ghaskins
2016-08-31 14:52
oh, i see
shireesh18
2016-08-31 14:52
Have used the command as mentioned in the doc to clone git clone && scp -p -P 29418 :hooks/commit-msg fabric/.git/hooks/
ghaskins
2016-08-31 14:52
I just use "git clone "
ghaskins
2016-08-31 14:52
which I got from the gerrit UI
ghaskins
2016-08-31 14:52
that seems to work…i havent tried the method in the docs
ghaskins
2016-08-31 14:53
if you find the above works (adjusted for your LFID) please file a doc bug in JIRA
ghaskins
2016-08-31 14:53
I got that link from https://gerrit.hyperledger.org/r/#/admin/projects/fabric
shireesh18
2016-08-31 14:53
@ghaskins let me try that
ghaskins
2016-08-31 14:54
Oh I see where the doc author got that: its if you click the “Clone with commit-msg hook"
ghaskins
2016-08-31 14:54
my guess is you havent configured your SSH key, in which case both methods should fail
ghaskins
2016-08-31 14:54
also note that you only need the SSH method if you plan to submit patches
ghaskins
2016-08-31 14:55
if you dont, you can just use: git clone http://gerrit.hyperledger.org/r/fabric
thomas.marckx
2016-08-31 15:01
@shireesh18: https://hub.docker.com/u/hyperledger/
Have a look at the tutorials to see how docker works
shireesh18
2016-08-31 15:05
@ghaskins I did configure SSH keys both private and public and I have added the public key in http://gerrit.hyperledger.org under settings--->SSH Public Keys
ghaskins
2016-08-31 15:08
@shireesh18 if none of the clone methods work and you get that error, I suspect you need to review your ssh setup

Hi QQ: If I create few peers using `docker-compose up` from vagrant host where are peer logs will be located, logs related to chaincode execution? Can they be accessible just from vagrant host or shall I ssh to peer using `docker exec` command? Also in my example peers are started in dev mode - does it make any difference for the logging?
Also what will be the most appropriate channel here for asking such env specific questions? :slightly_smiling_face:

Sawtooth and Fabric are both implementation of the same Hyperledger vision/protocol right?
Does that mean they should eventually be able to talk to eachother?
And what does Bletchley add? They still talk about Hyperledger as being a generation 1.0 blockchain in their whitepaper...

@david.acton ./safety_device will register the safety_device chaincode in the blockchain. I deployed the same code in IBM bluemix and its working fine. Peer port is correct one as I found it by running **netstat -atp tcp | grep -i "listen"** command. I am using docker toolbox for mac as an option for fabric runtime env. Below is the jira ticket for this bug but I don't know whether the issue has been resolved or not. (https://jira.hyperledger.org/browse/FAB-246)

@matanyahu - do you really want to build the fabric outside of Vagrant or are you really trying to *run* the fabric outside of Vagrant? Docker images are published - you should take a look at the chaincode development section of readthedocs where it describes how to run Docker images of peers and membership services. Unless you actually plan to contribute code changes to the fabric, you should simply be able to use the published Docker images

@garisingh : thanks for your response. Currently vagrant builds all components into a single VM. I wanted to build and run it in enterprise-like conditions, where redundancy must be preserved, i.e. multiple VMs and docker engine cluster. This does not exclude contributing to an existing effort :slightly_smiling_face:

Just to make sure that I get it right: after I successfully deploy new dev environment with vagrant I should build the fabric core and run unit tests (http://hyperledger-fabric.readthedocs.io/en/latest/dev-setup/build/). But what is the next step to complete my dev setup? Setting Up a Network For Development, Writing, Building, and Running Chaincode in a Development Environment and then eventually Certificate Authority (CA) Setup?

Fabric devs - for a chaincode development project, which fabric version do you recommend? The v0.5 version from the github, or is there a Gerrit tag that can be used?
venkat
2016-09-03 13:08
My hunch is, v0.5 could have mre un-fixed bugs than Gerrit, and we might not get much help from this community if we report issues while using v0.5. But then I'm not sure if Gerrit code has any "stable" tags or atleast closer to creating one such tag.
venkat
2016-09-03 13:09
Any suggestions?
garisingh
2016-09-03 13:11
@venkat - there is a new release being planned (v0.6) for later this month ( @cbf ? ). The v0.5 branch no longer exists in the github mirror. I'd stick with working with the latest for now
venkat
2016-09-03 13:12
Thank Gari - that's what I thought too.

Jut one more question - is HFC/NodeSDK working fine with Gerrit code? We seem to have run into issues.
garisingh
2016-09-03 13:15
are you doing `npm install hfc` ? I have not tried that latently against the master branch, but the SDK code in the master branch appears to be working (I have pushed a fix minor fixes and all my tests are passing)
garisingh
2016-09-03 13:16
what issues are you seeing?
venkat
2016-09-03 13:17
Will ask my devs to post the issue here. We are almost thinking whether we should stick to v0.5 if we have to use nodeSDK. I'm sure that sould not be the case.
garisingh
2016-09-03 13:18
great- can you make sure they post to the #nodesdk channel ?
venkat
2016-09-03 13:18
Sure.

venkat

@matanyahu - for some reason, there is no latest tagged base image. However, you can either pull the other base image tagged "x86" etc and re-tag it as "latest" or build the code and it should produce a latest image.
matanyahu
2016-09-03 14:26
@venkat : do you mean line 34 in setup.sh ?
venkat
2016-09-03 14:26
not sure about the line, but regading pulling base image.
matanyahu
2016-09-03 14:35
@venkat : OK, got it, I will wait until the setup fails, log on into vagrant vm, pull the image and rename it
matanyahu
2016-09-03 14:36
@venkat : do you think http://hyperledger-fabric.readthedocs.io is still the most relevant manual for fabric deployments and testing?

does anyone know which script actually invokes pulling docker images for hyperledger? Vagrantfile invokes setup.sh. Within setup.sh there is a reference to host.sh. However, in neither file there is an actual operation for pulling relevant images. Within vagrant-provisioned VM I've seen docker.sh which *probably* does this job but I cannot see a link between executables ran by Vagrant and this file. I am obviously missing something.

I have questions about a smart contract. As we know, the definition of a smart contract is the contract that will execute itself when it meets the defined condition.
Questions,
please correcting my understanding of Hyperledger/Fabric:
1. In the Hyperledger/Fabric, smart contract is the deploying chaincode.
2. The chaincode will be executed only when we deploy/invoke on it.
3. The chaincode is *not* a persistent process that can be run forever on it own.
4. The chaincode is stateless, and impossible to store any temporary value on it.
5. Making a smart contract on the Hyperledger/Fabric means to invoke the function on our customized chaincode by the external caller. e.g. calling the function through REST API, SDK, etc.
So, if my understanding is correct, is the chaincode smart?
stylix
2016-09-05 07:02
The scenario for example,
we want to transfer money from *A* to *B* at tomorrow 15:00
So, how can we implement a smart contract correctly?
Currently,
1. I implemented simple functions, e.g. create_acc() and money_transfer(), then deploy it as a chaincode.
2. Create users *A* and *B* with the initial money.
3. If I want to transfer money at 15:00, I have to call money_transfer() at 15:00. (not smart)
4. The block is then appends to the chain.
Can I implement the function that will accept a transaction with a specific contract detail, then the chaincode will execute for me.
e.g. Submitting a transaction at 8:00, transfer money from *A*->*B*, exec at 15:00?
bgorman
2016-09-05 07:02
@stylix the chaincode can persist state between invocations... GetState() PutState()
bgorman
2016-09-05 07:05
the time thing is interesting... you could technically write a chaincode that is long-lived and waits until 15:00 to commit
bgorman
2016-09-05 07:05
but it won't be on the blockchain until then
stylix
2016-09-05 07:06
Yes, that is what I think it is smart.
stylix
2016-09-05 07:07
I mean, I just want the value to be store temporary on the chaincode, and when the condition meet, the block is then append to the blockchain.
stylix
2016-09-05 07:08
GetState and PutState will interact with the current state from the blockchain, somehow from the validating node, not from the variable of the chaincode.
stylix
2016-09-05 07:08
If my understanding is correct.
stylix
2016-09-05 07:08
BTW, please correct me if I'm wrong, somewhere
bgorman
2016-09-05 07:08
if the peer doesn't reboot, you could very well let the chaincode sleep until a specific time... maybe even write a temporary file to disk?
bgorman
2016-09-05 07:09
you're pretty free to do what you want in the chaincode
bgorman
2016-09-05 07:09
you could have a "temporary" space on disk (not on the chain) that the peer maintains...
bgorman
2016-09-05 07:10
not sure how you would check it on startup to load those still-pending transactions though... perhaps another type of "startup" invoke
stylix
2016-09-05 07:10
You mean, R/W file? well that's another way
bgorman
2016-09-05 07:10
I take it you're comparing to Ethereum... do you know how it happens in those systems?
stylix
2016-09-05 07:10
BTW, if the chaincode done, it will not be back until I call it from API
stylix
2016-09-05 07:11
I don't know how Etherium works in practical, actually.
bgorman
2016-09-05 07:12
another idea would be you could have a chain for "pending" transactions and a chain for "committed" transactions... then you just need a way to check and commit them at the right time ... perhaps an independent program?
stylix
2016-09-05 07:14
How about, can I implement a kind like event emitter on the chaincode?
And this event will be fired, like javascript, e.g. setTimeout ?
stylix
2016-09-05 07:14
That will be interesting, and that's exactly smart contract, probably.
bgorman
2016-09-05 07:14
there are events ... I'm not familiar with them though
bgorman
2016-09-05 07:15
you can definitely invoke one chaincode from another too
stylix
2016-09-05 07:15
You mean, one normal chaincode, and one timer-like chaincode?
stylix
2016-09-05 07:16
and timer chaincode will run indefinitely? kind of?
bgorman
2016-09-05 07:16
as long as the peer doesn't shut down, I think they can run forever, yes
bgorman
2016-09-05 07:17
so you could have a chaincode that accepts a "singleton-timer" function... then a "add-new-timer-task" function
stylix
2016-09-05 07:18
Now sure how heavy load of this chaincode...
stylix
2016-09-05 07:18
Probably while(true) {
GetState()....
}
?
bgorman
2016-09-05 07:19
that one? a lot
put some sleeps in there :slightly_smiling_face:
stylix
2016-09-05 07:19
And can we trust a time of the container?
lbonniot
2016-09-05 07:20
@stylix you might find this one interesting https://golang.org/pkg/time/#Ticker
stylix
2016-09-05 07:20
To be exactly a smart-contract platform, I think this should be with Hyperledger job, actually.
stylix
2016-09-05 07:21
I'm checking...
stylix
2016-09-05 07:24
Well, I will check about Ticker, it must be kind of interesting. But not sure if it will fire at the specific time after I called it within an invoke
stylix
2016-09-05 07:24
BTW, thanks for @bgorman and @lbonniot . Now I have some idea to try.
bgorman
2016-09-05 07:26
good luck :slightly_smiling_face:
bgorman
2016-09-05 07:27
I'm tempted to read up on how Ethereum would work with your example
stylix
2016-09-05 07:28
Me too, not sure how the others work, smartly.
Thanks you, again, btw :slightly_smiling_face:
bgorman
2016-09-05 07:28
"smart" is just hand waving for "programming" :smile:
bgorman
2016-09-05 07:29
it's just a matter of who has to do the programming
stylix
2016-09-05 07:31
well, let's embed the 'smart' to each transaction, that's a bit smarter. haha
stylix
2016-09-05 07:34
BTW, can we actually create a variable on the chaincode? I mean local variable, not to use PutState/GetState.
stylix
2016-09-05 07:38
With that, it will let timer works, otherwise I need to go through while(){ sleep... } which will may caused the whole chain sleep, and may caused some negative affects about synchronization....
stylix
2016-09-05 07:38
BTW, just ask, I'm trying my side..
bgorman
2016-09-05 07:42
@stylix when you're writing your chaincode (e.g. in Go) you can do pretty much whatever you like locally
bgorman
2016-09-05 07:43
so `var <name> <type>` to make local variables
lbonniot
2016-09-05 07:45
@bgorman are these variables conserved between queries / invokes / reboots? And if we use local files, are they kept in the container between peer restarts?
If yes, that's pretty cool :slightly_smiling_face:
bgorman
2016-09-05 07:47
no, they're not, they're local
bgorman
2016-09-05 07:47
file between restarts? I guess that might work
bgorman
2016-09-05 07:48
if you want variables to persist between queries/invokes/reboots then you should use PutState() :slightly_smiling_face:
bgorman
2016-09-05 07:48
save them to some specially named key that won't be used otherwise
lbonniot
2016-09-05 07:49
thanks, I'm just working on something that might need each endorsing peer to hold different (secret) data, so files could be the answer :wink:
bgorman
2016-09-05 07:49
(not you can't PutState in a query)
bgorman
2016-09-05 07:49
@lbonniot sounds like a plan, just make sure your peers don't get their disks wiped :slightly_smiling_face:
bgorman
2016-09-05 07:49
or keep them in another blockchain I guess
lbonniot
2016-09-05 07:50
sure!
stylix
2016-09-05 07:56
When I first trying to learn Go, that's the same time when I'm trying to understand Hyperledger :stuck_out_tongue:
Well, just to confirm some understanding,
A deployed chaincode actually run forever with shim.start() to listen on the gRPC from the validating peer.
And we can create any local variable on our chaincode_xxx.go, which will be persistent as just a normal process.
And storage, is to keep it persistent after reboot, etc.
stylix
2016-09-05 07:57
I see, thanks, I'm trying, will see the result..
bgorman
2016-09-05 08:00
the chaincodes actually run as their own docker container inside hyperledger/fabric... thinking about it I'm not sure how persistent their disks are
bgorman
2016-09-05 08:00
so deploying a chaincode really starts up a new container
stylix
2016-09-05 08:00
I think we cannot mount the external volume on the chaincode container, at least this version...
bgorman
2016-09-05 08:01
the chaincodes also run on each peer... so if something is derived from a local file on disk, your other peers might not have it and might not reach consensus
bgorman
2016-09-05 08:01
sounds like an interesting thing to try out
stylix
2016-09-05 08:05
Yes, interesting, at least some kind of value need not to be stored in the chain.
Btw, a bit complicate, if the system shutdown...
Thinking about the better way..

Can we send the data to peer, which has the attachable volume?
In that case, peer can store the data locally, and can send the data back to the chaincode when it need to be recovered.
stylix
2016-09-05 08:09
But I think, peer does not have this ability this time.
stylix
2016-09-05 08:10
... just my first randomized idea.
bgorman
2016-09-05 08:15
If it affects the block chain then all peers would need that data

Assuming that you are really looking to be able to develop and test chaincode, you might want to have a look at http://hyperledger-fabric.readthedocs.io/en/latest/Setup/Chaincode-setup/

```

hi, everyone, I have a question. We know that fabric rest api is based on swagger. And so I am using swagger client generator to generate client sdk for golang. The generated code looks seems good, but can't be use. ```"ConfidentialityLevel":{
"type": "string",
"default": "PUBLIC",
"example": "PUBLIC",
"enum":[
"PUBLIC",
"CONFIDENTIAL"
],
"description": "Confidentiality level of the Chaincode."
},```
mint
2016-09-05 17:53
ConfidentialityLevel will be generated as ```
/*ConfidentialityLevel Confidentiality level of the Chaincode.
swagger:model ConfidentialityLevel
*/
type ConfidentialityLevel string
// for schema
var confidentialityLevelEnum []interface{}
func (m ConfidentialityLevel) validateConfidentialityLevelEnum(path, location string, value ConfidentialityLevel) error {
if confidentialityLevelEnum == nil {
var res []ConfidentialityLevel
if err := json.Unmarshal([]byte(`["PUBLIC","CONFIDENTIAL"]`), &res); err != nil {
return err
}
for _, v := range res {
confidentialityLevelEnum = append(confidentialityLevelEnum, v)
}
}
if err := validate.Enum(path, location, value, confidentialityLevelEnum); err != nil {
return err
}
return nil
}
// Validate validates this confidentiality level
func (m ConfidentialityLevel) Validate(formats strfmt.Registry) error {
var res []error
// value enum
if err := m.validateConfidentialityLevelEnum("", "body", m); err != nil {
return err
}
if len(res) > 0 {
return errors.CompositeValidationError(res...)
}
return nil
}
```

Hi guys, is there any documentation around how to spawn a Non Validating Peer please? I am trying to spawn a Non Validating Peer to communicate with a four peer network and so far not a lot of luck….
bgorman
2016-09-06 06:29
@heshanp is it not the same as when you run a normal peer, except set CORE_PEER_VALIDATOR_ENABLED=false (or equivalent in a peer/core.yaml)?
heshansp
2016-09-06 06:35
@bgorman: Exactly my understanding as well so far but how is it going to communicate with a given validator? Can I invoke a function in the NVP using CLI? I can't get these to work.
bgorman
2016-09-06 06:39
it communicates the same way as the other peers, over gRPC, and I think it talks directly to whichever peer you specified as CORE_PEER_DISCOVERY_ROOTNODE
bgorman
2016-09-06 06:40
I seem to be able to invoke CLI commands on my NVP

{"Peers":[{"ID":{"name":"vp1"},"address":"172.17.0.3:7051","type":1},{"ID":{"name":"vp0"},"address":"172.17.0.2:7051","type":1},{"ID":{"name":"vp2"},"address":"172.17.0.4:7051","type":1},{"ID":{"name":"vp3"},"address":"172.17.0.5:7051","type":1}]}
note that .6 is not part of the peer network list
heshansp

So does a NVP get a copy of the chaincode? I guess thats a no...
bgorman
2016-09-06 06:40
no, it wouldn't need it
heshansp
2016-09-06 06:41
So how will it validate the request coming through CLI please? Does it run its own GO code with a main func?
bgorman
2016-09-06 06:42
my understanding is that NVPs get a copy of the current blockchain state (e.g. a rocksDB) to handle `query` requests... anything else gets sent to a VP
bgorman
2016-09-06 06:43
hmm... query would need the chaincode
bgorman
2016-09-06 06:43
let me spin up some chaincode :slightly_smiling_face:
stylix
2016-09-06 06:44
In my case, there is no block in NVP, and I can query only from VP.
stylix
2016-09-06 06:46
Not sure if I missed some parameter, but it happens
bgorman
2016-09-06 06:47
definitely not got any chaincode running on my NVP
heshansp
2016-09-06 06:49
Hmmmmmm interesting... So how exactly is the NVP signing the transaction before sending to the VP?
bgorman
2016-09-06 06:50
signing?
heshansp
2016-09-06 06:51
Oh I mean adding the security metadata
bgorman
2016-09-06 06:51
@stylix I seem to be able to query my NVP, get the same results as the VPs
bgorman
2016-09-06 06:52
I can even invoke on the NVP
bgorman
2016-09-06 06:53
@heshansp sorry, not sure what or if the NVP adds to the requests on the way to the VP
bgorman
2016-09-06 06:53
my NVP is definitely not handling the chaincode side of things ... the logs just show a transaction ID and nothing else

@bgorman I was referring to this example here... https://github.com/hyperledger/fabric/tree/master/examples/chaincode/go/asset_management/app where the NVP adds the security metadata to the transaction which gets validated by the VP.
abhishekseth
2016-09-06 06:57
Hey all,
I am running in “non-dev” environment. Therefore, I need to give the url to the chaincode in the “path”. But most of the tym, I get this error which is very frustrating.
{
"jsonrpc": "2.0",
"error": {
"code": -32001,
"message": "Deployment failure",
"data": "Error when deploying chaincode: Error getting chaincode package bytes: Error getting code Getting chaincode took too long"
},
"id": 1
}
Anyone having any clue of it?
bgorman
2016-09-06 07:01
@abhishekseth you could try increasing the `chaincode.deploytimeout` setting...?
stylix
2016-09-06 07:01
@bgorman How could you query on NVP? What I did is actually through REST, and I have nothing on it.
bgorman
2016-09-06 07:02
it looks like it's running `go get` on your chaincode package and has a timeout occurring
bgorman
2016-09-06 07:02
@stylix I'm using the CLI - `CORE_PEER_ADDRESS=172.17.0.6:7051 peer chaincode query -c '"function":"query", "args":["a"]'`
bgorman
2016-09-06 07:02
.6 is my NVP
bgorman
2016-09-06 07:03
the actual query seems to be handled by the VP still
stylix
2016-09-06 07:03
Umm, strange. It should not be different. I will try it with CLI, then.
bgorman
2016-09-06 07:04
@abhishekseth looks like that timeout is 30s by default ... if your network is slow or your chaincode large, that might not be enough
abhishekseth
2016-09-06 07:23
@bgorman , okk.. i will try increasing it.
abhishekseth
2016-09-06 07:26
Hiii,
How do we make sure whether Attribute certificate authority is running properly or not?
What kind of logging we get on terminal after enabling this?
In my docker-compose.yml file, I did - MEMBERSRVC_CA_ACA_ENABLED=true
heshansp
2016-09-06 07:37
So guys I'm still not sure about how a NVP is going to validate a request if the only thing it does is pass on the message to the validating peer.
bgorman
2016-09-06 07:40
@heshansp is this still regarding the description at https://github.com/hyperledger/fabric/tree/master/examples/chaincode/go/asset_management/app ?
heshansp
2016-09-06 07:41
Yes sir....
bgorman
2016-09-06 07:41
that looks like it's a stand-alone app that runs and interacts with the NVP
bgorman
2016-09-06 07:42
I don't see the bit that says the NVP does validation
heshansp
2016-09-06 07:42
Interacts? Hmmmmmm I thought the app initiates the NVP... Isn't that what main function is doing?
bgorman
2016-09-06 07:43
ah you're right, the app acts as an NVP
bgorman
2016-09-06 07:43
submitting things to the VP
heshansp
2016-09-06 07:43
Exactly!!
heshansp
2016-09-06 07:43
So that's the one I'm after.... Because I have a very similar usecase...
heshansp
2016-09-06 07:46
So in a scenario like this, is there a way for CLI to interact with the app? Would the REST API still work?
bgorman
2016-09-06 07:47
do you mean use the `peer` CLI to interact with the asset_management app?
heshansp
2016-09-06 07:47
Hmmmmmm yes.....
heshansp
2016-09-06 07:48
Is that even possible?
bgorman
2016-09-06 07:50
sorry, I'm not sure
bgorman
2016-09-06 07:50
it would depend on what the app implements really
heshansp
2016-09-06 07:53
So my dilemma is that my chaincode expects security metadata just like the asset management chaincode here.... Without a NVP executing the transaction I have no way of adding the metadata to the request...
bgorman
2016-09-06 08:12
do the VPs not embed the same meta data?

I am currently working on a practical use for Hyperledger Fabric where the blockchain would become a single instance of knowledge about assets which would be used for a more effective analysis by external analytical mechanisms. I will make three major assumptions about the data and the process related to this use for clarity:
(1) The Fabric network would be capable of sending and receiving data from/to outside world through API and chaincode.
(2) Data source from which some date would interact with blockchain would be provided in a standardized format with exactly the same kind of information residing in fixed locations across databases.
(3) Whatever changes happen in account A, they will also be reflected by changes in account B, although both accounts may not necessarily be aware of each other. Within the blockchain network, they would be two completely separate entities with separate tCerts issued to change their state. An example would be a simple accounting excercise where payment of 50USD from A to B would mean that A would incur a change of -50USD in their books, whereas B would incur a change of +50USD in their books.
With that in mind, I will describe the subject-matter of my problem described below:
One of crucial aspects related to the solution is the kind of information and its format that can be reasonably retained within the blockchain without impacting its performance, scalability and security. I am currently analyzing different approaches to data processing by taking into account Fabric's main features, such as Consensus, Provenance, Finality and Immutability. However, I want to make sure that I do not step on a landmine I would not be able to defuse once it's too late.
Therefore, I am taking an assumption that:
(a) the Blockchain should not be considered as an equivalent to a database. It can rather be compared to the ledger
(b) Therefore, it should not be used for amounts and types of data typical to relational databases (RDBMS), unstructured databases (NOSQL/Hadoop) or data warehouses.
This means that real data should be kept (conserved) in a structured format on an external (central) database. Here, blockchain's role could possibly be used as:
- a hash list proving existence of an immutable piece of data
- an archive for some particular entries extracted from a external database(s) used for reconciliation of conflicting information between various data sources
- a ledger grouping some variables extracted from central database(s) under a single (unique) account with a possibility of tracing changes horizontally (cross-comparison with other accounts) and vertically (changes across time within a single account). Vertical tracing (changes within a single account) would be possible through a clustered analysis of tCerts provided by the CA to sign new transactions
Can someone please confirm, correct, append or deny abovementioned assumptions?
p.s. Although there is a possibility to perform vertical tracing with tCerts, I find no possibility to have clustered analysis made horizontally (i.e. across accounts). Here I need to assume that external analytical tools would have to be used to take all tCerts and compare their changes one against another.
matanyahu
2016-09-06 13:03
Otherwise, can someone please direct me to a documentation that describes: (a) how data is stored and structured within PBFT-consensus-driven blockchain and (b) how blockchain data is persistent if peers are based on Docker images.

I created #playbacks channel in slack, for folks that want to do playbacks on their recent work. There is a group of folks working on the ledger, that did some charts and a video playback, which is awesome. Just a 2 min video, or written explanation works well too. There will be more coming soon and regularly. If there is a google drive or different location that we should post these let me know, else will use slack for now as they code is churning quickly so long term storage is probably not an issue.

Hi
Yesterday I asked about debugging and got some answerd from @garisingh, @mint , @donnieg, @hgabor. Thank you for that. It helped to improve my development process.
However it is still not ideal. Let me explain more precisely what I really would like to have:
Ideally, I would like to be able to run debug for Go chaincode in my IDE (like LiteIDE for ex) and be able to use some standard features: breakpoints in the code, Step Into & Step Over commands, watch variables as any step, etc. Currently, if I do that in LiteIDE get error "peer.address not configured, can't connect to peer" somewhere in the err := shim.Start(new(SimpleChaincode)) of the main() function. Is there a way to avoid that error by some config changes or something? Or set up debug in any other way?

Hi All -
I'm following the network setup instructions http://hyperledger-fabric.readthedocs.io/en/latest/Setup/Network-setup/ to run multiple peers on a single VM (setup via Vagrant) and I was just wondering how the peer node decides which core.yaml file to read when it is launched? In other words when launching a peer node via the "docker run ... hyperledger/fabric-peer" command what is the search path for determining the core.yaml file to read configuration from.
Kind Regards,
Graham
garisingh
2016-09-07 12:16
@gnsortino - the peer image itself contains the core.yaml file. So technically if you start multiple peer containers they are actually using identical configurations. Right now, there is no externally mounted volume to pick up a different core.yaml per container instance. The simplest thing to do is to actually use something like Docker Compose and then override per container settings for core.yaml using environment variables - e.g.
```
membersrvc:
image: hyperledger/fabric-membersrvc
ports:
- "7054:7054"
command: membersrvc
vp0:
image: hyperledger/fabric-peer
ports:
- "7050:7050"
- "7051:7051"
- "7053:7053"
environment:
- CORE_PEER_ADDRESSAUTODETECT=true
- CORE_VM_ENDPOINT=unix:///var/run/docker.sock
- CORE_LOGGING_LEVEL=DEBUG
- CORE_PEER_ID=vp0
- CORE_PEER_PKI_ECA_PADDR=membersrvc:7054
- CORE_PEER_PKI_TCA_PADDR=membersrvc:7054
- CORE_PEER_PKI_TLSCA_PADDR=membersrvc:7054
- CORE_SECURITY_ENABLED=true
- CORE_SECURITY_ENROLLID=test_vp0
- CORE_SECURITY_ENROLLSECRET=MwYpmSRjupbT
links:
- membersrvc
command: sh -c "sleep 5; peer node start --peer-chaincodedev"
```

@garisingh Thank you. Just to make sure I understand correctly... if I use docker compose all settings will default from the core.yaml file associated with the docker image but I can override core.yaml settings using the docker-compose.yml file?
garisingh
2016-09-07 12:24
yeah - the `environment` section will allow per container instance override - so for example you can give each peer container a different `CORE_PEER_ID`,`CORE_SECURITY_*`
gnsortino
2016-09-07 12:24
cheers. I think I understand this now. Many thanks again
garisingh
2016-09-07 12:25
the naming of environment variables is to use `CORE_` as the prefix and then just capitalize any parameter from the core.yaml and replace `.` with `_`

There are two DEPLOY in this example, zVMuser01 and zVMuser02.
Afte r I deploy zVMuser01, I will QUERY(zVMuser01) get output from the query.
I then DEPLOY it again for zVMuser02 and it does not get deployed as you can see in the log.
To get DEPLOY it again, you will see a KILLED of the chaincode EBS. I then re-started again, and now I DEPLOY zVMuser02 with SUCCESS.
Now I QUERY zVMuser02 with SUCCESS but when I query zVMuser01 I got Decryption failure

could you set all logging levels to debug? in core.yaml somewhere under logging, e.g. chaincode: debug
garisingh
2016-09-08 10:20
@echenrunner - you are trying to deploy 2 different instances of the chaincode using the same name (`mycc`)
garisingh
2016-09-08 10:21
this will be problematic as each chaincode must have a unique name
garisingh
2016-09-08 10:22
the question I have is are we really trying to run separate chaincode instances or do you want to be able to store the data for both `zVMuser01` and `zVMuser02` in the same instance of chaincode?

Hi Garisignh, I'm trying to store data for both zVMuser1 and 2. I also set DEBUG and the output is very large. Are you also saying zVMuser01 run chaincode "mycc" and "02" runs "mydd" ? Thanks

2016-09-08 15:24
sorry @echenrunner - so there are 2 options:
1) If you want a single instance of the chaincode, you should add another function which basically does the same thing as you are doing on deploy (so basically create an "AddUser" function and call it from init if you want to add a user during deploy and then call it using an invoke transaction to add additional users after deployment)
2) If you really wanted multiple instances of the chaincode, then use different names each time you deploy
echenrunner
2016-09-08 15:50
Hi Garisingh, Option1. I did something similar where in the INVOKE I issue "PutState" for zVMuser02 as a go around. I am going to create new function... better ideal. Thanks for the help

hi guys, I'm looking at the asset_management02_test.go program where it basically call the asset_management02's functions(deploy, invoke and query) . I would like to use curl json but I'm running problem of alice.GetTCertificateHandlerNext("role", "account1", "contactInfo") as to how to put it in json. I'm learning as I go. Thanks

@mart0nix https://github.com/hyperledger/hyperledger/blob/master/hyperledger_Overview_Comparison_Guide.md is a comparison guide.

In short, Sawtooth-Lake and Fabric are both projects within hyperledger.

Hi fellows, wondering if some one can help with following
I've cloned the "learn chain code" repo (https://github.com/IBM-Blockchain/learn-chaincode.git)and trying to build the very first program with Go
when I run " go build ./ " it spits out following error
\chaincode_start.go:34: cannot use new(SimpleChaincode) (type *SimpleChaincode) as type shim.Chaincode in argument to shim.Start:
have Init(*shim.ChaincodeStub, string, []string) ([]byte, error)
want Init(shim.ChaincodeStubInterface, string, []string) ([]byte, error)
Any ideas ?
garisingh
2016-09-10 14:38
we are trying to figure out the best way to modify the repo examples to work with multiple versions of the fabric, but in the meantime you should be able to find and replace `*shim.ChaincodeStub` with `shim.ChaincodeStubInterface`
adeelqureshi

Current fabric version in Bluemix is 0.5 but your code is 0.6 compatible only.

@gaurav you are not the first who runs into this problem (as I remember). last time I tried, it worked, and the unit tests also try that chaincode (others, correct me if I am wrong). could you please tell me the exact steps to reproduce the problem(s)?
gaurav
2016-09-12 06:24
@bgorman @hgabor steps to reproduce:
1. checked out the latest version of hyperledger fabric source from gerrit repository
2. vagrant up
3. started membersrvc and node peer start
4. copy from fabric\examples\chaincode\go\chaincode_example02 $GOPATH/src/github.com/chaincode_example02 and setup the vendor directory with latest of hyperledger as vendor/github.com/hyperledger
5. try to deploy $GOPATH/src/github.com/chaincode_example02 using the latest version of the hfc node sdk version 0.5.2
bgorman
2016-09-12 06:25
is step 4 really necessary?
gaurav
2016-09-12 06:26
yes i think its necessary while deploying with hfc as per the readme at https://www.npmjs.com/package/hfc
bgorman
2016-09-12 06:28
wow ok, I need to learn how to use the hfc :slightly_smiling_face:

@gaurav how to setup that vendor directory?

2016-09-12 07:33
could you please detail step 5. ? I have never ever tried deployment with node sdk
gaurav
2016-09-12 07:37
in the vendor directory you need to create the complete fabric source obtained from gerrit at vendor/github.com/hyperledger/fabric
gaurav
2016-09-12 07:37
for step 5 let me share the source
hgabor
2016-09-12 07:54
okay, I am finished with the vendoring, lets go deploy :slightly_smiling_face:

Hi; question about the REST API. I have a question about how I should be attempting to performance/stress test Hyper Ledger via the REST API.
1) Is an "OK" response to an invoke request an indication that the transaction has finished, or just that the network has received the request?
2) I measure transactions per second as follows: (# requests) /(timestamp of the last BLOCK on the ledger - timestamp of the first TRANSACTION on the ledger). Is this valid?
Thank you!

@vzhou Hi Vzhou.. I’m not an expert, just another user, but as I understand it, OK just means it’s received the request. You have to query the returned transaction ID I believe, to find the result.

Can anyone summarize which ports are used by the current Fabric?
Previously, I the ports are used in the old Fabric as follow
REST: 5000
CLI: 30304
gRPC: 30303
Validator: 31315
Well, I'm going to check, just to confirm if someone already have the list.

Hello all,
For the attribute level security, fabric maintains membersrvc.yaml file which have some attributes defined like position,company, account, role etc and internally a table is maintained for these attributes names and values.
Is there any way by which we can dynamically assign the roles to the new users and then depending on their roles, different attributes access is given to them?
abhishekseth
2016-09-13 06:36
Basically, I do not want to use this membersrvc.yaml file for maintaining attributes definitions. Is there any way to do this?

@abhishekseth I think the node SDK will let you register/enroll new users in an ad-hoc manner... so for example you could write an app to maintain a database of users elsewhere

hgabor
2016-09-13 07:53
look: https://github.com/docker/docker/blob/master/builder/dockerfile/dispatchers_windows_test.go the error is related to file paths, so somehow somewhere docker gets a path that it is unable to normalise

hgabor
2016-09-13 08:40
maybe try the following... could you set chaincode logging level to debug?
yls

yes, other code are deleted for debug the error
hgabor

hgabor

but have you tried with chaincode logging set to debug?
hgabor
2016-09-13 09:18

Hello all, I have a question, does chaincode be able to deploy another chaincode?
hgabor
2016-09-13 11:05
I don't think, but it can call one
lbonniot
2016-09-13 11:10
As long as it's able to call the Grpc endpoint of one peer, it should be able to deploy, right?
oiakovlev

not really - you have to try. As query is not allowed to call invoke. If you try, could you, please, post results here?

When cloning fabric v0.6 (and using Vagrant), when I start the membersrvc, nothing is output (it did in v0.5). When I run 'docker ps -a' it also doesn't show the membersrvc and peer docker containers running. Any idea why this is happening?

In Fabric each chaincode is deployed in separate Docker container, when a chaincode invoke another chaincode, are they communicate between container?

@zhangsoledad it might be via the peer, but yes

@xinghua I mean it might be using something like your $PYTHONPATH or $PYTHONHOME variable (if you have one)

@leuchine you either need to set the CORE_PEER_ADDRESS correctly (or peer: address: in peer/core.yaml)
or... set the CORE_PEER_ADDRESSAUTODETECT=true (peer: addressAutoDetect: true)
bgorman
2016-09-15 07:01
0.0.0.0:7051 isn't a valid IP, you could try 127.0.0.1:7051

Hi, is it possible to test hyperledger without installing docker?

ghaskins
2016-09-15 13:57
@shenthilkumarck short answer: no
ghaskins
2016-09-15 13:57
long answer: you dont need to run the peer network in docker, but the peer itself uses docker to run chaincode
ghaskins
2016-09-15 13:57
so even if you run it natively, docker still needs to be present

ghaskins
2016-09-15 14:01
(though the “isolation” part is still pretty weak today
ghaskins
2016-09-15 14:01

Hi, Is it correct that no information in ledger can be protected from viewing by every Validation peer in a native way? Let's say I put a document into ledger. And I need some fields of the document be visible to subset of validating peers only. In that case I need to cipher the values and share the key to the subset of VP outside of the ledger.
lbonniot
2016-09-15 14:58
@andriian hi! That's how I would proceed, but I'm really interested to know if a native way is available / is planned

maybe with transaction confidentiality / endorsement policies (planned in the next architecture I think)

Hi! I'm trying to understand fabric a little better and I have read almost all the documentation and whitepapers, I've still some important questions and I'm not completely sure where to ask them. The questions span from "how I make it all in one War file?" to "what DB is using to store the blockchain?", any help would be appreciated
andriian
2016-09-15 16:04
@fabcan Hi. "what DB is using to store the blockchain?" - it is RocksDB, which is key/value type DB

gnsortino
2016-09-15 16:20
I don't know the answer to that but I doubt its using a database in the traditional sense of the term
gnsortino
2016-09-15 16:25
It's a good question because I don't believe I've come across any documentation discussing storage. My suspicion is that it uses a similar process to the bitcoin ledger/blockchian, which I think is basically just writing out to the filesystem but I haven't hunted through the hyperledger code base enough to be able to say.

@arvin when you deploy do you see new containers with the name vp1-dev-chaincodehash, vp2-dev-hash etc starting up? Might take some time after deploy (initially a minute even) check docker status with docker ps -a...
szlaci83
2016-09-15 22:25
When you deploy you get the chaincodehash even if the deploy was not succesful (at least in v0.5)

I just heard that the REST API on fabric would be deprecated soon and gRPC would be the only way to communicate with fabric. This sounds strange to me, as I feel REST is still way more popular and well-understood than gRPC for enterprise integrations. Can someone throw light on the rationale behind this decision? Thanks.

My question is, for simple cases where the existing REST API is good enough, why should we force an extra layer of complexity by way of having to maintain a nodejs/hfc client?

@szlaci83 I deploy by 0.0.10,On one host dev environment it will be success(and i can see the vp1-dev-chaincodehash ),I can't get this when deploy on 4 Host.
arvin
2016-09-16 04:50
@shenthilkumarck I have try this way,It will be success. Why I deploy on 4Host with net mode,the log still tell me you config is dev.

While deploying name is not necessary, Once you successfully deployed you will get a hash value. You should use that hash value as name while query and invoke.
ranjan008
2016-09-16 06:00
then without name its giving the handler error

Hey all,
I had some doubt:
Let say there are 4 peers who did transaction at the same timestamp and assume all those transactions try modifying the data of the same person.
How will it work?
Whose transaction will be validated and added since there is no time lag among these 4 transactions.

@humblealex no problem
humblealex
2016-09-16 08:37
@abhishekseth I think that depends on the consensus mode. In PBFT, the request will be validated through peers first, and then transaction will be executed on each peer locally, of course the blocks will also be added locally. ONly after a certain number of transactions, the block info will be validated through peers. It doesn't matter when the transaction gets executed.
abhishekseth
2016-09-16 08:49
@humblealex , Consider two peers debit an amount of 100 rs at exactly same time from an a/c which does have only 100 rs. So, whose transaction will be validated. I mean how to handle these kinds of situtaions?
humblealex
2016-09-16 08:58
@abhishekseth In that case, the two peers both have the blocks with the information of having 100 rs in that account, when the transactions got exectuted on both peer individually, they will both have 100 rs deducted and the result will be added to the blocks respectively. In the current fabric, the result is not validated through consensus. In your case, if the client query the peer who hasn't finished the transaction, he will get the wrong result.Only if he wait a little while until both peers finish the transaction.
humblealex
2016-09-16 09:18
@abhishekseth I once deployed a chaincode which creates ramdon numbers. But still the transactions got executed and all the peers had different results written in the blocks. There is news indicating that they are now focusing on the consensus issues.
ranjan008
2016-09-16 09:24
can we modify the .yaml file which is inside the chaincode after deploying it to the chain
garisingh
2016-09-16 09:31
@abhishekseth - transactions will be processed in order - so one of the debit transactions will be executed before the other. Remember that executing a transaction actually runs the chaincode. So in your chaincode of course you would check to make sure that the account had a sufficient balance before actually applying the debit.

@garisingh what if both the transaction were done on different peers at the exactly same time?
garisingh
2016-09-16 09:49
all transactions will go through consensus first for ordering
garisingh
2016-09-16 09:51
so let's say client1 submits transaction to peer1 and and client2 (or could be client1) peer2 at exactly the same time. With PBFT, both peer1 and peer2 will then "submit" the transaction to consensus which will order the transactions and send back to all the peers who will than execute the transactions in order

@venkat: we are consolidating on one means of access for security (less exposed surface area) and to reduce complexity and potential for technical debt.
we are focusing attention on the node (and other) SDKs as the preferred means of interacting with the fabric components via grpc.
cbf
2016-09-16 11:24
@ranjan008: modifying the core.yaml after starting the peer will likely have no effect. There is a certain amount of caching of the config at start-up.
you are better off using environment variables at start-up to make config changes. This is an area we recognize needs improvement.
ranjan008
2016-09-16 11:27
@cbf that's right but i am not talking about the core.yaml file i am talking about the yaml file which is given under chaincode folder under example there is chaincode in go with name "asset_management02" which contains a yaml file.

garisingh
2016-09-16 14:49
@venkat - I think I mentioned this elsewhere - removing REST from the peer does not mean we can't provide a REST API "server" which communicates with the peers. We'll get to that as we progress
venkat
2016-09-16 14:55
Ah - that is exactly what I was looking for. If I'm writing a chaincode app for tracking changes to a single table, can I just rely on using REST? If the answer is yes, then I can defer my HFC/Node stuff to later when I really need it.

When using PutState is it possible for the value to be anything other than a string of bytes? For example, if the PutState call defines a transaction could there be information about why the transaction is made, etc... effectively adding some sort of metadata. Or alternatively is there another data structure one would use to record this sort of information?

@garisingh - removing REST on validating peers should not be a concern, as the apps mostly connect to non-validating peers. However, can yu assure that the NV peers will continue to support REST for forseeable future?
garisingh
2016-09-16 15:12
@venkat - once we finalize the v0.6 branch / release of fabric, we won't be making any major changes to that codebase. The focus will move to focus on the fabric.next architecture (fabric v1.0). So we won't be ripping anything out of the v0.6 codebase. In fabric v1.0, we won't have the concept of NVPs and we won't have a transactional REST interface built into the various peer nodes

transactions are processed asynchronously so even though you get the transaction id back upon submitting the transaction, it does not mean that the transaction has completed and/or was successful. You might want to check the logs of your peer to see if there are any errors processing the transaction

Heads-up on Sawtooth restructure. We've moved most of core/ into validator/ including gossip, journal, and ledger. Those are not backward compatible changes. If you need the previous structure please use 0.6.

garisingh
2016-09-21 09:01
@shimron - the easiest way to register new users will be to use the NodeSDK. But I'll assume that your interest is in doing this from Golang. The problem is that somewhere in the code you are using its importing gorocksdb (fabric vendors this as a dependency).
The gorocksdb package is actually dependent on the rocksdb library. You'll need to pass in
```
CGO_CFLAGS=-I/opt/rocksdb/include
CGO_LDFLAGS=-L/opt/rocksdb -lrocksdb -lstdc++ -lm -lz -lbz2 -lsnappy
```
garisingh
2016-09-21 09:02
in order to build. Note that you would need to replace `/opt/rocksdb` with whatever the path to rocksdb src is on your machine
shimron
2016-09-21 09:08

As people move from 0.5 to 0.6- the chaincode interface was updated from *ChaincodeStub to ChaincodeStubInterface. Basically to update a chaincode for v0.6, search for "*ChaincodeStub" and replace with "ChaincodeStubInterface".
More detail:
Changeset https://gerrit.hyperledger.org/r/#/c/365/
v0.5 Chaincode interface
type Chaincode interface {
Init(stub *ChaincodeStub, function string, args []string) ([]byte, error)
Invoke(stub *ChaincodeStub, function string, args []string) ([]byte, error)
Query(stub *ChaincodeStub, function string, args []string) ([]byte, error)
}
v0.6 Chaincode interfacetype Chaincode interface {
Init(stub ChaincodeStubInterface, function string, args []string) ([]byte, error)
Invoke(stub ChaincodeStubInterface, function string, args []string) ([]byte, error)
Query(stub ChaincodeStubInterface, function string, args []string) ([]byte, error)

How do we implement access control for the users of a chaincode app? Do we have any docs or samples? The membership services doc seems to address CA setup, but not about access control for the users of a chaincode app.
venkat
2016-09-22 06:26
For example, my chiancode would like to identify the user who is making the request through HFC, and their application role, and accordingly allow them to invoke txns or query data.
venkat
2016-09-22 06:29
What will the NodeJS app send to chaincode via HFC, as user credentials for the access to chaincode?

@bgorman :thank you for your reply ,i tried it and got the result Received REGISTERED, ready for invocations.
then i ssh to a new window and make the request
peer chaincode deploy -n mycc -c '{"Function":"init", "Args": ["a","100", "b", "200"]}'
it shows me [crypto] Errorf -> ERRO 01c [client.] Failed loading certificate [eca.cert.chain]: [ope
n /var/hyperledger/production/crypto/client/ks/raw/eca.cert.chain: no such file or directory].

@bgorman ,i think it's something wrong about register, and i try to use peer network login lukas, also shows me error :Failed registering client [lukas] with name [lukas][rpc error: code = 14 desc = grpc: RPC failed fast due to transport failure]. any idea ?

When trying this out on docker, the guide does not appear to show that Go is needed http://hyperledger-fabric.readthedocs.io/en/latest/Setup/Chaincode-setup/

@ant2221 indeed, good catch

cbf
2016-09-22 17:27
@ant2221 @ghaskins well, in the Vagrant and Docker cases, Go is included for you. You do not need it installed. If you intend to build natively on Mac, Linux or Windows, then yes we probably should stipulate that prerequisite.
cbf
2016-09-22 17:29
ah, I see, it could be the case for building the chaincode natively

2016-09-22 17:29

Some have asked about where to find backlog proposals from IBM contributors. To find proposed backlogs take a look at the public boards that were created for various components such as ledger, consensus, endorser, etc. Each will contain the current thinking of backlog and current thinking relative to priorities. We would like feedback and if there are user stories or tasks that look interesting please jump in.

I need some help in debugging the chaincode. I am using a permissioned blockchain and have created a smartcontract that enforces some access control e.g. `only a specific user can invoke a method`. But I am getting error back saying `Invalid hash algorithm` when I invoke `stub.VerifySignature` in chaincode. I am using `asset_management` chaincode as reference to implement my chaincode...any suggestions on how to debug?
Is there a way I can see the logs from chaincode? I am using logger returned by `shim.NewLogger` to log in my chaincode...
`hashAlgorithm` in both `core.yaml` and `membersrvc.yaml` is set to `SHA3`

@shimron chances are that you are already enrolled

in which case it will no longer accept your enrollmentSecret. You can clean your DB and try again.

the register user request must be signed by the registrar's enrollment key, if the client does not have that, it cannot register a new user with this registrar
maltaf
2016-09-23 07:31
I would suggest you clean your db using ```rm -rf /var/hyperledger/production/``` and then enroll admin before registering a new user
shimron
2016-09-23 07:35
@maltaf well… I’m trying to integrate the CA’s grpc service with my own golang codes http://hyperledger-fabric.readthedocs.io/en/latest/API/MemberServicesAPI/

@maltaf ok, I’ll try to clean the db. thanks for your reply :grimacing:
maltaf
2016-09-23 07:37
so when you enrolled the admin, did you receive the enrollment certs? you should save them and when using admin as registrar to register the new user, please use this key to sign the request for create user
maltaf
2016-09-23 07:38
you can have a look at the https://docs.google.com/document/d/1R5RtIBMW9fZpli37E5Li5_Q9ve3BnQ4q3gWmGZj6Sv4/edit#heading=h.z6ne0og04bp5 for more details about this process
maltaf
2016-09-23 07:39
the Spec is still under development, but you'll get the idea
maltaf
2016-09-23 07:39
of course after every unsuccessfull attempt, you'll need to clean your db because a user cannot be enrolled or registered twice
shimron

maltaf
2016-09-23 07:46
The new token is the challenge you are supposed to decrypt and then send a new request after signing the request with signing key. It looks like you didn't sign the request with correct key. I would suggest you take a look at the spec
maltaf
2016-09-23 07:46
it has code examples to solve the problem
shimron
2016-09-23 07:50
@maltaf thanks a lot, I’ll check it :grimacing:

Hi all, I'm new to hyperledger and we are trying to test out the marbles (and other) demos. We have a hyperledger network running on a Mac and also on a POWER8 machine. We are using the fabric docker implementation. We can deploy chaincode to the networks just fine in chaincodedev mode, but in standard mode we get errors when we try to deploy code. It looks like it can't start the container for the chaincode. See output below. If anyone else has had this problem, we would love some help :slightly_smiling_face:

I was curious if anyone within Hyperledger community is working on an orchestration mechanism that would allow to easily set up the entire network through a series of simple questions, close to what Microsoft announced during DEVCON2 for its private Ethereum network offering. Bluemix does it partially - it sets up a network but it does not give much of flexibility with regards to the deployment options

Since I haven't received any answer, I will ask this question again: out of curiosity - why was it decided to deprecate REST API calls in Fabric? I find it fairly convenient a way to communicate with the blockchain and its components.
mart0nix
2016-09-25 18:13
@matanyahu I guess the decision was to migrate to the new SDK
chetsky
2016-09-25 18:49
@matanyahu I can't speak for the HLF maintainers (I'm not assuredly not part of that group), but consider that both HTTP and various connection-ful protocols exist in the world. And I think it's fair to say, you wouldn't want to use HTTP to talk to your mysql database (or memcached) as the default case. Of course, there are cases when you want to -- and for those, one puts a proxy in front of mysql (as, I believe, facebook did). I would expect that there would be (or somebody would write) a REST proxy front-end, in the fullness of time.
chetsky
2016-09-25 18:52
connection-ful protocols allow for easy management of buffers, security-contexts (and ensuring that they get populated before anything else transpires), queueing notifications, etc. You can do all of this with a connection-less protocol, but for starters, you have to use timers to decide when to discard these data-structures. Sure, with a connection-ful protocol, one is relying on the kernel's timers and lookup-tables in the typical cases, it's much, much easier.

How to make hyperledger VP REST API return error message on Invoke?
tribbloid
2016-09-25 22:44
According to [this answer](http://stackoverflow.com/questions/39508739/hyperledger-fabric-chaincode-invoke-function-return-values), it doesn't work the same way as Query

Hi all, a question for the car-lease-demo. It uses V5C_Holder struct to hold all the vehicles in the network for querying, I wonder whether there's a better or more efficient way to iterate on all the vehicles? Thanks all
xixuejia
2016-09-26 00:51
if I want to query the vehicles by owners, I don't want to do iterations on all vehicles in the ledger, is there a way to do that?

hi all, last week i am success to get my develop enviroment with vagrant,then i want to try the application enviroment.
i use docker-took-box and pull hyperledger/fabric-peer:latest and pull hyperledger/fabric-membersrvc:latest, when i try to deploy chaincode_example02, it shows me launchAndWaitForRegister failed Error starting container: Tag latest not found in repository http://docker.io/hyperledger/fabric-baseimage
should i pull fabric-baseimage? i use yml file and peer node start and not --peer-chaincodedev.

matanyahu
2016-09-26 16:06
@mart0nix : I would nuance this a bit. Ethereum and Hyperledger have completely different use cases and both can perfectly co-exist. I would not underestimate Ethereum community since recently Brian Behlendorf (Hyperledger boss) invited them with open arms to contribute into Hyperledger "umbrella" projects
matanyahu
2016-09-26 16:06
for obvious reasons, the governance of public vs private ledgers is different and recent two DDoS attacks on Ethereum which were repelled rather swiftly show that core devs and decision makers learned few lessons after DAO/ETC stories
cbf
2016-09-26 17:02
@sbrakev AFAIK, there hasn’t been an update - lots of prep for SIBOS and some of Brian’s other presentations.

@matanyahu Ethereum could also be used as a private ledger - nothing prevents you from running a private blockchain with geth
mart0nix
2016-09-26 18:51
the reasons I'm not optimistic about their long terms prospects has to do with the fact that 1) they tought dApps would be a real thing (having to download, install and configure a crypto-desktop app is not going mainstream any time soon) 2) scalability and privacy were at best after-thoughts and 3) they burned millions of dollars with little to show for it (imagine how far a US-style start-up would have gone with that much money - the etherum guys basically burned through all this cash for what 2 years ?
mart0nix
2016-09-26 18:52
and 4) try developing and running an app in solidity that goes beyond the hello world example

matanyahu
2016-09-26 19:01
I still see quite a lot of potential for Ethereum as a community of business people, entrepreneurs, corporate giants and devs because they have a first entrant advantage (Smart Contracts) and a vast array of devs behind. I also appreciate their openness to topics which are taboo within Bitcoin community, such as inter-chain co-operation, acceptance for private blockchain use cases and diversity of ideas. I also think Ethereum people are much more business-minded than people in Bitcoin community.
matanyahu
2016-09-26 19:02
Nevertheless, Bitcoin community also has some outstanding figures so I am definitely not going to generalize here
matanyahu
2016-09-26 19:03
What these communities lack (and I believe this is a true advantage of Hyperledger community) is an ability to DELIVER real solutions that respond to BUSINESS NEEDS (sorry for caps)
lenh
2016-09-26 19:03
+1
mart0nix
2016-09-26 19:04
@matanyahu I see - you are looking at this from the Bitcoin perspective
mart0nix
2016-09-26 19:04
in that regard I'd agree with you
mart0nix
2016-09-26 19:04
but let's agree here that after $150M ethereum is still vaporware (unfortunately)
lenh
2016-09-26 19:05
it's not to the people that own the ETH - THAT'S the point...
yale.reinstein
2016-09-26 19:05
yes it is.

2016-09-26 19:05
@mart0nix : I understand and appreciate your point but I will gladly not agree on the vapourware part :slightly_smiling_face:

@matanyahu what are the ethereum apps you are currently using ?

2016-09-26 19:09
Nope but that's not my point :slightly_smiling_face:
lenh
2016-09-26 19:09
the issue is how do we get Fabric to be easily accessible at all levels (community fabric contribution, community ChainCode, and web API's)
matanyahu
2016-09-26 19:09
I am gladly exploring both ethereum and hyperledger and I see value in both

2016-09-26 19:20
this is NOT about fin Serv
matanyahu
2016-09-26 19:20
that's what makes Hyperledger (Fabric) an advantage : an ability to deliver a solution with the existing code
matanyahu
2016-09-26 19:20
because there are some actors participating in this project who are truly capable of delivering
lenh
2016-09-26 19:21
yes - you are right - TODAY - but as the eco-system evolves and the tools, etc etc get better more people get drawn in and, and and....
matanyahu
2016-09-26 19:22
@lenh : please develop your thought further
mart0nix
2016-09-26 19:23
he means that the it's the people with business background who are developing hyperledger (as opposed to the fan boys (decentralize the future!!! lol)
mart0nix
2016-09-26 19:25
so when you look at hyperledger - you see all the things you would want to have in an enterprise blockchain platform (scalability, privacy, security, existing language for chaincode, identity management, etc..)
mart0nix
2016-09-26 19:25
different people look for blockchains for different reasons
mart0nix
2016-09-26 19:25
I have a particular business case where something like hyperledger would be a lot more appropriate (and usable )
mart0nix
2016-09-26 19:26
I'm sure you can run geth on some crapy hardware and do IoT kind of thing if you want to ...
mart0nix
2016-09-26 19:26
so blockchainers of the world...unite!
lenh
2016-09-26 19:27
my point is simply this - right now HL is "hard"to play with.... needs skill, determination, what we call "vasbyt" (if you don't know what that is google it!)... BUT as more people get involved, more intellect gets applied, the "easier" it becomes for "early" adopters.. and time progresses it becomes mainstream... "I need to do a distributed ledger app (!purposly NOT using "blockchain buzzword") - what should I use" --- dude ever heard of Hyperledger....
yacovm
2016-09-26 19:29
I think you raise a good point here. We have a devenv vagrant, maybe we should also have a "ready-to-go" vagrant image with everything installed without a script but rather in the image itself, and that starts up everything on machine boot?

matanyahu
2016-09-26 19:31
@yacovm : I've been thinking about it with my friend, actually developing and ovf file with some questionnaire that would deploy the whole devenv with specific configuration in place. We will be working on it in 4Q16
lenh
2016-09-26 19:32
there's three layers here:
1) fabric contributors... (special breed of gifted coders who want to much more in it for the community...)
2) chaincode (less so but also help develop chaincode patterns, etc)
3) web devs hwo just wanna "impress" by being able to access a given industry's ledger

just to be taken into account
lenh
2016-09-26 19:52
100% - I fully accept, appreciate and admire that... BUT if we all want this tech to be "the" eco-system then we need to acknowledge the fact that getting people to commit their time and energy will require "an easy intro- and adoption path"... that's all I'm saying...
matanyahu
2016-09-26 19:53
hopefully this will happen soon - the recent vagrant up was definitely much better than even a month ago
matanyahu
2016-09-26 19:53
I wish there was more synchro between up to date Fabric and what is published on Bluemix

2016-09-26 19:54
yes agreed - all credit to @ghaskins
yacovm
2016-09-26 19:57
@matanyahu why would you need a questionnaire? why not just deploy a standard single validator with noops and that's it?
lenh
2016-09-26 19:57
but that / this is the point - no matter how much frustration we may may feel right now - if we all work together - in our own ways and with the the individual skills we all bring the eco-system will become more robust making the learning barrier of entry for future participants less...
lenh
2016-09-26 19:58
and the lower the barrier of entry the ^ the adoption over other platforms / ideas / etc

that's where 1 vp with noops does not suffice

@yacovm - the point is - if we are going to dev chaincode and webapps we need an environment that truly depicts production... devenv for fabric contributors is 100% solid now after the changes that @ghaskins did - BUT it's nowhere near what mainstream devs need to drive adoption.... - we need to put more effort into making it "easy" for people to play...

basically no business will want to trust a network without a basic premise of blockchain which is a consensus algorithm
lenh
2016-09-26 20:29
depends on the business need / requirement

with regards to number of nodes, there are tons of reasons not to stick to a single VP, starting from those of contractual nature (parties to the newly established business network deploy 1 VP for each) as continuing with technical architecture (resilience, service availability, integrity of data etc.)
lenh
2016-09-26 20:33
what I do know is the principle of community adoption = having a chance of becoming something....
matanyahu
2016-09-26 20:33
so, 1 VP + noops is good for devs but not good for business, even for PoC

@matanyahu : 100% in agreement!
lenh
2016-09-26 20:36
we need to understand the 3 layers....
1) fabric devs - the current devenv serves them well...
2) chaincode devs - current setup --- meh...
3) web app devs - current setup - give me a break!

Please let me know if this question doesn't belong to this channel. I recently started playing with hyperledger fabric. I setup hyperledger fabric on my mac using docker for mac. I am able to use rest API to communicate with memversvc and peer. I am trying to compile peer command to use CLI. But I am running into the folling error when I run make: "Step 2 : ADD gopath.tar.bz2 $GOPATH/src/github.com/hyperledger/fabric
Error processing tar file(bzip2 data invalid: bad magic value in continuation file):
make: *** [build/image/src/.dummy] Error 1"
sandeep.kanaparthi
2016-09-26 20:39
Any help is appreciated.
mart0nix
2016-09-26 20:39
@sandeep.kanaparthi abandon the REST API
mart0nix
2016-09-26 20:39
use the new SDK
lenh
2016-09-26 20:40
see my point!
sandeep.kanaparthi
2016-09-26 20:41
REST API is working fine for me. I am not able to compile peer for CLI
lenh
2016-09-26 20:41
REST API is deprecated - don't spend dev time on that path...
mart0nix
2016-09-26 20:42
@sandeep.kanaparthi I abandoned the REST API and the CLI - use docker set-up + SDK - this is how I managed to get up and running on Mac
lenh
2016-09-26 20:44
we need that seperation, fabric/chaincode/web app
sandeep.kanaparthi
2016-09-26 20:45
Thanks.
lenh
2016-09-26 20:45
devenv for each...
matanyahu
2016-09-26 20:45
next consensus architecture is supposed to separate fabric from chaincode
lenh
2016-09-26 20:47
and docs for dev workflows - ok sure we appreciate atm chaincode is gonna be go / java... but seriously web app side - we gotta open this up folks....
sandeep.kanaparthi
2016-09-26 20:49
I am trying to eliminate webapp layer to keep it simple. I am working on a client side demo (JS) app that communicates directly with fabric with rest API. It should work right?
mart0nix
2016-09-26 20:50
there's no webapp layer right now
mart0nix
2016-09-26 20:50
the SDK is JS
mart0nix
2016-09-26 20:50
node.js apps basically
lenh
2016-09-26 20:51
I thought the comms layer is gRPC
sandeep.kanaparthi
2016-09-26 20:51
can I use this JS SDK in the browser?
lenh
2016-09-26 20:53
and THAT's my point! if we want community adoption then...
lenh
2016-09-26 20:54
3 layers - fabric, chaincode and who the hell cares
lenh
2016-09-26 20:54
why are we pushing to a given stack
lenh
2016-09-26 20:55
who cares what the the web app folks wanna use - or am I really missing something here!?
lenh
2016-09-26 20:56
I get it on the fabric side - fully!
lenh
2016-09-26 20:56
I kinda get it on the Chaincode side....
lenh
2016-09-26 20:57
But on the web app side -if we want ADOPTION... well then....\
mart0nix
2016-09-26 21:11
@lenh I don't quite understand what you are saying
mart0nix
2016-09-26 21:11
the web side is WIDE open right now
mart0nix
2016-09-26 21:12
you can do a node js app or a go app or what ever app
mart0nix
2016-09-26 21:12
that's the point of gRPC after all
mart0nix
2016-09-26 21:12
the web side has lowest priority here in my mind until the other layers stabilize as things are in flux right now
mart0nix
2016-09-26 21:13
at some point there would be a PHP SDK, Python SDK, etc...
mart0nix
2016-09-26 21:14
but this is going to come from the community developers
mart0nix
2016-09-26 21:14
not the core developers who working on the middle ware
lenh
2016-09-26 21:23
@mart0nix - I fully 100% understand that the web side has the lowest priority in your mind - and things are in a state of flux... but not being a contributor to the core fabric myself (and my team) AND wanting to be part of the community working (NOT ON the core) but building the real world apps that could potentially make this platform the go-to-platform of choice my comments are purely coming from the "how can we make this the best possible dev eco-system for possible blockchain/hyperledger adopters" as possible...
lenh
2016-09-26 21:24
it's NOT a criticism by any means...
mart0nix
2016-09-26 21:25
well I think you have three options
mart0nix
2016-09-26 21:25
1) wait until the web layer is mature
lenh
2016-09-26 21:25
all i'm saying is we need a bigger / wider community with people a lot smarter than me to get involved...
mart0nix
2016-09-26 21:26
2) start writing node.js SDK app examples so people can get into it right away
mart0nix
2016-09-26 21:26
3) start campaigning for hyperledger OUTSIDE of slack, because here you are preaching to the converted
lenh
2016-09-26 21:30
How about....
1) leave the core fabric dev to those gifted enough to play in that space...
2) help "middle-of-the-road" dev's who can perhaps get industry specific chaincode going a chance... and
3) give the web folks a break....
lenh
2016-09-26 21:31
we all have a role to play if it's truly going to be a community play....
lenh
2016-09-26 21:33
if there is one thing I know as regards dev projects it's this - being inclusive = getting a whole hellofalot more support than being exclusive
lenh
2016-09-26 21:37
we have a chance here of starting / assisting a broad-reaching movement of individuals who support the use of hyperledger as the go-to platform for distributed ledger tech....
lenh
2016-09-26 21:37
as long as we are inclusive....

when i deploy the chaincode and init like a,100,b,200,i can get a chaincode,then i can use the chaincode to do invoke and query, but next i do init c,300,d,400, i get a new chaincode, how can i do the invoke between a and c? i can just do between a and b or c and d. the twice init gives me different chaincode.
chetsky
2016-09-27 02:26
@teddy oh wow, that's the default behaviour?
chetsky
2016-09-27 02:26
is there a way to cause the second Init() to fail?
teddy
2016-09-27 02:33
@chetsky thank u.
yes, i use the example chaincode_example02.
does you mean that i can only do once init() and the other param like c,d,e... i need to write a func for add the value to the ledger? if not ,i dont know what is the point
chetsky
2016-09-27 02:34
well, it's been a long time since I used HL. So let me be sure what you did: Init(a,b) ; Pay(a->b); Init(c,d); Pay(c->d)
chetsky
2016-09-27 02:34
all this works, right?
teddy
2016-09-27 02:35
yes,you are right
chetsky
2016-09-27 02:35
So if you did: Init(a,b) ; Pay(a->b); Init(c,d); Pay(c->d); Pay(b->a)
chetsky
2016-09-27 02:35
does that last Pay(b->a) work?
teddy
2016-09-27 02:40
i do pay like this:
peer chaincode invoke -n 69cee27c44c6df29d4fc1dc27572ea32fcb6a1098913edb29b2d2b7f8d1239bc139e43f8f0c886e1cb04f4fbb409d2e2c28f861b6272ba0b7bd26ee19d39cb27 -c '{"Function": "invoke", "Args": ["a", "b", "10"]}'
the -n chaincodeID is returned by the init(a,b), the init(c,d) return a different id. so it works for pay(b->a). i use the docker-tool-box.
chetsky
2016-09-27 02:40
ok. so Init() returns a chaincode ID,. Let me amend my previous little script
chetsky
2016-09-27 02:41
id1:=Init(a,b) ; id1.Pay(a->b); id2:=Init(c,d); id2.Pay(c->d)
chetsky
2016-09-27 02:41
that works, right?
chetsky
2016-09-27 02:41
and id1:=Init(a,b) ; id1.Pay(a->b); id2:=Init(c,d); id2.Pay(c->d); id2.Pay(b->c)
chetsky
2016-09-27 02:41
the last id2.Pay() fails, right?
teddy
2016-09-27 02:42
yes, just like that
chetsky
2016-09-27 02:42
now, if you add id1.Pay(b->a) to the end, does that succeed?
chetsky
2016-09-27 02:42
note "id1"
teddy
2016-09-27 02:47
yes, when i use id1, it means i can just do pay between a and b, id2 : c and d, but i can not do pay between a and c
chetsky
2016-09-27 02:48
bright.
chetsky
2016-09-27 02:48
right
chetsky
2016-09-27 02:48
ok ........
chetsky
2016-09-27 02:48
can I ask: are you comfortable with any object-oriented programming languages?
chetsky
2016-09-27 02:48
Init() is effectively the constructor
chetsky
2016-09-27 02:48
and the chaincode ID you get back is the "address" of the object
chetsky
2016-09-27 02:49
so yes, if you want to pay between b, c, you need to create c's account in the same instance as b'c account
chetsky
2016-09-27 02:49
I think chaincode_example_02 has no "create-account" entrypoint, but you could add that, yes?
chetsky
2016-09-27 02:49
honestly, Init() shouldn't take any parameters.
chetsky
2016-09-27 02:50
so it should really go like:
chetsky
2016-09-27 02:50
id:=Init() ; id.Create("a", 100); id.Create("b", 200); id.Create("c", 100); id.Create("d", 200) ; id.Pay("a", "b", 10); id.Pay("c", "a", 20) ......
chetsky
2016-09-27 02:50
etc
chetsky
2016-09-27 02:50
see what I mean?
teddy
2016-09-27 02:53
thank you.. i use java, so i think i know what you mean. so i need write my own chaincode for init:grinning:
chetsky
2016-09-27 02:54
well, just modify chaincode_example_02, perhaps?
teddy
2016-09-27 02:55
maybe, i will read the code.:+1:
bgorman
2016-09-27 02:56
@teddy I think you might be better off modifying the Invoke() to handle a new function (like the existing "delete" in there)? e.g. Invoke("add", "c", "123")

@marryton007 - I think the issue is that that sample is completely out of date / out of sync with the current REST API. We should probably remove that sample entirely at this point. If you are interested in building a NodeJS application which interacts with the fabric, I'd suggest using the NodeSDK - `npm install hfc`
marryton007
2016-09-27 10:35
@garisingh thanks for reply, I'll try it.

it looks like there are duplicates that prevent new registration of the same user ...?!?

In the protocol spec, it says in section 3.2.2.1.1 that the key in the world state is represented by as concatenation of chaincodeid and key, so does it mean, if you deploy two chaincode on the network. If you call get from one chaincode, can you retrieve the data added by other chaincode. I am just trying to understand whether the data inserted by one chaincode is accessible only from that chaincode.
tuand
2016-09-27 13:23
data from a chaincode is stored in a separate namespace, not accessible from others

RocksDB supports pluggable compactions and pluggable memtables. Are we using any plugins with RocksDB ? Also what is the version of RocksDB that is used in Hyperledger ?
cbf
2016-09-27 14:03
@gauthampamu 4.1 and no, we aren’t using any plugins
cbf
2016-09-27 14:03
there is some refactoring of the ledger underway to allow more flexibility in the choice and config of the underlying db

is it better to use Docker on my local? or use vagrant ?
thomas.marckx
2016-09-27 14:57
I’m having difficulties enrolling new users.
Currently I just add them in the membersrvc.yaml, after which I delete everything in /var/hyperledger/production.
I rebuild the membersrvc and run it
(I also start a new peer).
This works sometimes but now I keep receiving the following error
```{ Error: 'rpc error: code = 2 desc = Identity or token does not match.’ }```
I understand that password in the yaml is view as a one-time, but I expect this be “reset” when I delete everything in production
Anyone have an explanation ?
wangmzdl
2016-09-27 14:57
I used vagrant destroy, then vagrant up

@tuand If the data from a chaincode is stores in a separate namespace. To workaround this…Can you make a copy of the database and can you develop alternate implementation of hyperledger that would allow you to read the data added by other chaincode assuming you know the other chaincode id.
tuand
2016-09-27 15:47
@gauthampamu ... what's your use case ?
gauthampamu

Its not for specific use case. I want to understand the security of the world state data stored in the ledger.

I assume that you are trying to make an XHR request from a browser to the REST API of the fabric?
You would not set this in chaincode as the peer communicates with chaincode via a GRPC channel. The easiest thing to do will be to run a simply proxy server in front of the REST API which sets the CORS headers you want

2016-09-27 21:40
@sandeep.kanaparthi I built a Fabric prototype over the weekend whose UI needed CORS support. I setup an Nginx proxy to inject the headers, but it turned out in the end that the peer was already emitting the necessary HTTP headers. Hence, it appears that the peer natively supports CORS. If the values it sets though are not suitable, I'm not sure if it is possible to change them via configuration.
ccooper21
2016-09-27 21:45
If you do need more control and want to use Nginx as a reverse proxy, here is how I did it by cobbling together various Internet postings:
```
server {
listen 0.0.0.0:80 default_server;
location / {
if ($request_method = 'OPTIONS') {
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
#
# Custom headers and headers various browsers *should* be OK with but aren't
#
add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type';
#
# Tell client that this pre-flight info is valid for 20 days
#
add_header 'Access-Control-Max-Age' 1728000;
add_header 'Content-Type' 'text/plain charset=UTF-8';
add_header 'Content-Length' 0;
return 204;
}
proxy_pass_header Authorization;
proxy_pass http://172.17.0.1:7050;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_http_version 1.1;
proxy_set_header Connection "";
proxy_buffering off;
client_max_body_size 0;
proxy_read_timeout 36000s;
proxy_redirect off;
if ($request_method = 'POST') {
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type';
}
if ($request_method = 'GET') {
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type';
}
}
}
```
sandeep.kanaparthi
2016-09-27 23:00
Yes. Peer is already sending CORS header. I should have looked closer. Thanks a lot.

If you're running with `CORE_SECURITY_PRIVACY=true` it will be also encrypted with your certificate, so it can be not just base64.

@xuxinlai not sure what would cause this yet, but we only support the virtualbox provider
ghaskins
2016-09-28 13:39
if I had to guess, id guess you do not have virtualbox installed
ghaskins
2016-09-28 13:39
and perhaps that kicks vagrant down to lxc as a default or something

When uninstall 5.1 and install the 5.0.Then It is OK now.
ghaskins
2016-09-28 13:42
to be clear: what were your versions of vagrant/virtualbox before and now?
xuxinlai
2016-09-28 13:43
The Vagrant is 1.8.1 and virtual box is 5.0
xuxinlai
2016-09-28 13:44
Vagrant 1.8.1 and virtual box is 5.0 is OK and Vagrant 1.8.1 and virtual box is 5.1 become error.
xuxinlai
2016-09-28 13:45
Vagrant 1.8.1 : virtual OK
Vagrant 1.8.1:virtual box error.
xuxinlai
2016-09-28 13:47
@ghaskins conclusion is:
Vagrant 1.8.1 and virtual 5.0 OK
Vagrant 1.8.1 and virtual 5.1 error
Vagrant 1.8.6 and virtual 5.1 OK
ghaskins
2016-09-28 13:48
ok, that makes sense, thanks for confirming
ghaskins
2016-09-28 13:48
ill see if theres anything I can do to make the error more obvious
ghaskins
2016-09-28 13:48
e.g. “virtualbox required” is better than “atlas::LXC not found"
ghaskins
2016-09-28 13:49
at least that would have pointed you in the right direction sooner

I have setup 2 peers with the help of the Fabric Network Setup on my mac using “docker for mac". I managed to deploy a CC then call the invoke function using the REST API calls.
While both the invoke messages resulted in a success the query message simply fails. This is weird as it works fine when the same set of commands are applied to a single peer instantiated in dev mode (peer node start --peer-chaincodedev).
Note that the 2 peers are setup using Docker containers. Here is an example of what the JSON response for query looks like:
{
"jsonrpc":"2.0",
"error":{
"code":-32003,
"message":"Query failure",
"data":"Error when querying chaincode: Error:Failed to launch chaincode spec(Could not get deployment transaction for 04233c6dd8364b9f0749882eb6d1b50992b942aa0a664182946f411ab46802a88574932ccd75f8c75e780036e363d52dd56ccadc2bfde95709fc39148d76f050 - LedgerError - ResourceNotFound: ledger: resource not found)"
},
"id":5
}
What could be wrong with my multiple peers setup?

hi, all, is there any membersrvc cluster/ load banlance solution yet?
ccooper21
2016-09-30 06:16
@sandeep.kanaparthi Someone can correct me if I'm wrong, but based on the chaincode examples I'm under the impression that if you want to maintain temporal state that you need to pull it along as you update the world state. In other words, before storing any new state, you'd need to load the previous state and merge it into the new state (e.g. some kind of compound JSON object) and then store the merged result into the world state.

Considering the fact that audit trail is one the use cases of blockchain, Is it on fabric roadmap?
ghaskins
2016-09-30 17:59
@echenrunner I am, but I am not really able to parse your issue
ghaskins
2016-09-30 17:59
what do you mean by “wrong key” ?
echenrunner
2016-09-30 18:05
stub.GetRow("AssistRequest", columns)
ghaskins
2016-09-30 18:12
ok, and I assume “abend” is a typo for “abort"
echenrunner
2016-09-30 18:16
yes. is a old mainframe terms
ghaskins
2016-09-30 18:17
ah. gotcha
ghaskins
2016-09-30 18:18
i just checked our code: we def use GetRow all over the place
ghaskins
2016-09-30 18:18
it does return an error tuple though…are you checking that?
ghaskins
2016-09-30 18:18
e.g. result, err := stub.GetRow()
ghaskins
2016-09-30 18:19
i have to step away, but I would look at it from thatangle
ghaskins
2016-09-30 18:19
at the very least, I would expect you to get an err returned, not an abort
ghaskins
2016-09-30 18:19
(sorry, “abend” ;)
echenrunner
2016-09-30 18:19
row, err := stub.GetRow
ghaskins
2016-09-30 18:19
hmm, sorry, not sure
ghaskins
2016-09-30 18:19
ours works, fwiw
ghaskins
2016-09-30 18:20
but I have to run, bbiab
echenrunner
2016-09-30 18:28
thank you
ghaskins
2016-09-30 18:32
Suggest running your chaincode in devmode using delve
ghaskins
2016-09-30 18:32
Also suggest switching to #fabric
echenrunner
2016-09-30 19:20
In the core.yaml I switch fron NET(docker) to DEV
ghaskins
2016-09-30 19:21
that might work, but that isnt how I run it, hold on let me find instructions
ghaskins
2016-09-30 19:22
i use the —peer-chaincodedev option
echenrunner
2016-09-30 19:22
That what I use as well.
ghaskins
2016-09-30 19:22
then you launch the code as per: http://hyperledger-fabric.readthedocs.io/en/latest/Setup/Chaincode-setup/#starting-and-registering-the-chaincode
ghaskins
2016-09-30 19:23
but you add “dlv …” in front
echenrunner
2016-09-30 19:23
yes.
ghaskins
2016-09-30 19:23
echenrunner
2016-09-30 19:24
the Dev is avoid the chaincode being run as docker.
ghaskins
2016-09-30 19:24
right, but it also gives you an opportunity to run it under a debugger such as delve
ghaskins
2016-09-30 19:25
generally you want to add “dlv exec” in front of the chaincode command
ghaskins
2016-09-30 19:25
YMMV
ghaskins
2016-09-30 19:26
ghaskins
2016-09-30 19:27
from there, I would go through the deploy+trigger steps from the client, and when the app aborts, you’ll get the dlv prompt back at the crash point
ghaskins
2016-09-30 19:27
if you are not familar with delve, its very similar to using gdb from the command line
echenrunner
2016-09-30 19:27
I am about the TRACE the code from the abort.
ghaskins
2016-09-30 19:28
(except its golang aware, like goroutines, etc
ghaskins
2016-09-30 19:28
cool, good luck!
echenrunner
2016-09-30 19:29
another question, did you run into an issue of enroll and user with incorrect password and then you correct the password and still won't work?
ghaskins
2016-09-30 19:30
no, but my usage is fairly basic
ghaskins
2016-09-30 19:30
i generally reset everything between cycles
ghaskins
2016-09-30 19:30
(i shut down client, peer, membersrvc, blow away their persistent state, bring them back up again
echenrunner
2016-09-30 19:31
I wonder if the one I pull from Aug is the old one. maybe this is the reasn
echenrunner
2016-09-30 20:28
from the TRACE/DEBUG +++ 16:20:41.205 [chaincode] func1 -> DEBU 13c9 [31facb28]No state associated with key: 16MYAssestTable16Cust_KEY. Sending RESPONSE with an empty payload from there it abort the chainCode with index out of range
ghaskins
2016-09-30 22:20
What is the stack trace on the actual abort?
echenrunner
2016-10-01 00:35
It points to the chaincode that issue the GetRow. I have question and is more of for everyone. In the z/VM mainframe community we have a workshop that runs once a year
echenrunner
2016-10-01 00:37
the workshop provides training given by users them self. I wonder if this something that we should have. Please go check the http://vmworkshop.org

if rowBytes == nil {
return row, fmt.Errorf("Error no row found from DB: %s", err)

ghaskins

@echenrunner is it hitting that error?

When trying to enroll a user I get...
```ERROR: failed to register admin: Error: Identity or token does not match```
but I've checked the membersrvc.yaml file and the password is correct. Any ideas anyone?
lenh
2016-10-01 17:49
Quick overview of my setup:
Fabric VM running on a specific IP
2. ssh then cd /opt/gopath/src/github.com/hyperledger/fabric/build/bin
3. membersrvc > membersrvc.log 2>&1&
4. peer node start --peer-chaincodedev
HostOS
1. node app calling the above on the assigned IP
The communication layer works as the error I'm getting is coming from the membersrvc (I think?)
lenh
2016-10-01 17:50
Basically I'm trying to get the chaincode_example02 running from a "remote" node app...
mart0nix
2016-10-01 17:50
@lenh I used to get this when attempting to enroll the same user twice
lenh
2016-10-01 17:50
aha - ok....
lenh
2016-10-01 17:51
so just for testing if I kill everything and delete the production dir and then start it all up and call the enroll once only from the node side it should work...?
mart0nix
2016-10-01 17:51
yeah
mart0nix
2016-10-01 17:53
@lenh the only 'advanced' samples I managed to run was the JS asset_management unit tests (via docker containers)
lenh
2016-10-01 17:55
ok - that worked although I got a `sending init` failed...
lenh
2016-10-01 17:56
but that's fine - the point was to check if the comms actually works - which I'm now satisfied that it does... thanks for pointer the one-time only enrollment requirement... forgot about that...
lenh
2016-10-01 17:59
what is strange though is I just ran the enrollment request again to check that it fails and it didn't... it went through fine
echenrunner

Hi everyone! Do you thing fabric will have an acceptable performance in case it have a 1000 users who may write transactions and something around 1 million read-only users in membership service?

SuSE Linux. My environment is vbox. what I have been doing is create vbox with SuSE Linux Leap4.2 and give it to my co-work so he can play around it when he is commuting on the train. it does kills time :slightly_smiling_face:

Hi everyone, If you are looking for help to navigate Jira and see what the current prioritized list is for fabric at least from my view, please see the #requirements channel. I ask if there is something in your mind that is out of priority order, or simply missing in the near term, please bring it up in the #requirements slack channel. I’m working to keep the list in order as best I can, but need your feedback as well to help rank these.

Hi,
I am trying to setup chaincode developer env by following http://hyperledger-fabric.readthedocs.io/en/latest/Setup/Chaincode-setup/ . I am on a windows 7 machine and using vagrant vm i.e. using option. I am not able to start peer and facing some issue. I have also asked a question regarding this at http://stackoverflow.com/questions/39865384/is-my-hyperledger-peer-make-successful . Can some one please help me out here?
yacovm
2016-10-06 08:30
@sadanandu can you try to do: `export PATH=$PATH:/opt/gopath/src/github.com/hyperledger/fabric/build/bin` ?

2016-10-06 09:13
then do "make membersrvc" , "which membersrvc" then "membersrvc"
yacovm
2016-10-06 09:16
and it's stuck like this?
sadanandu
2016-10-06 09:16
Yes
sadanandu
2016-10-06 09:17
I think it means peer is started in a container
yacovm
2016-10-06 09:17
can you do `docker exec -it c48c1b4f8f23 /bin/bash` ?
sadanandu
2016-10-06 09:17
Yes I could do that but I did not know what to do next

2016-10-06 09:18
umm I'd try to understand what's going on there
sadanandu
2016-10-06 09:19
Oh...there is a change now on the make peer window
sadanandu
2016-10-06 09:19
It went ahead
sadanandu
2016-10-06 09:20
And last statement is 'Binary available as build/bin/peer'
sadanandu
2016-10-06 09:21
This did not happen for last 2 days...when I was trying this out.... today after a lot of tries I gave docker tools a try
sadanandu
2016-10-06 09:21
May be that changed something
sadanandu
2016-10-06 09:21
Let me try 'peer node start ' now
sadanandu
2016-10-06 09:25
Finally I got this output:

@madhavi , could you give more details ? fabric or sawtooth ? what's the scenario ?
madhavi
2016-10-06 12:54
its fabric i started two peers like vp0 and vp1
madhavi
2016-10-06 12:54
by using vp0 i am able to deploy, invoke and query the chaincode
madhavi
2016-10-06 12:55
if i try to query the chaincode by using vp1 peer its not working
tuand
2016-10-06 12:55
@madhavi, since it's fabric, let's continue in #fabric channel

vigneswaran.r
2016-10-07 05:32
Have you started the peer service?
jmahhh
2016-10-07 05:32
yup
jmahhh
2016-10-07 05:32
looks fine
vigneswaran.r
2016-10-07 05:33
If you're using Linux machine, you can try the command "netstat -nlpt" to see what are all the services listening on which port..
vigneswaran.r
2016-10-07 05:33
By any chance you started the peer inside a docker image? In that case, your peer address may be 172.17.0.2 (instead of localhost 0.0.0.0)
jmahhh
2016-10-07 05:34
ah yes I tried that already
jmahhh
2016-10-07 05:34
didn't change anything
jmahhh
2016-10-07 05:34
is `mycc` correct..?
vigneswaran.r
2016-10-07 05:35
To me, it looks like a problem with peer service IP.. Need to provide the correct IP. Have you tried netstat -nlpt? Whether peer in running on the localhost?
vigneswaran.r
2016-10-07 05:36
chaincode name (mycc) is not a problem..
jmahhh
2016-10-07 05:36
`ip add` shows
```4: docker0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default

vigneswaran.r
2016-10-07 05:37
ok. have you started memebrship service also inside docker?
jmahhh
2016-10-07 05:37
no don't think I have
jmahhh
2016-10-07 05:37
I only have peers running at this moment
vigneswaran.r
2016-10-07 05:38
ok
jmahhh
2016-10-07 05:38
oh wait it's the same process
jmahhh
2016-10-07 05:38
```
docker-compose up
Starting hypertest_membersrvc_1
Starting hypertest_vp0_1
Attaching to hypertest_membersrvc_1, hypertest_vp0_1
```
vigneswaran.r
2016-10-07 05:39
yeah..
vigneswaran.r
2016-10-07 05:39
ok, then try 172.17.0.3 as the core peer address
jmahhh
2016-10-07 05:39
haha works!
vigneswaran.r
2016-10-07 05:39
ok :slightly_smiling_face:
jmahhh
2016-10-07 05:39
how come? Should the tutorial be adjusted?
vigneswaran.r
2016-10-07 05:40
172.17.0.1 is taken by docker0 on localhost. 172.17.0.2 is taken by membersrvc. The first peer will take 172.17.0.3 and so on
jmahhh
2016-10-07 05:41
alright cheers!
jmahhh
2016-10-07 05:41
I guess the yml file and that command may not be in sync
vigneswaran.r
2016-10-07 05:41
ok
jmahhh
2016-10-07 05:49
one more q... `peer: command not found`
vigneswaran.r
2016-10-07 05:50
if you have done "make peer", you can find peer executable inside "fabric/build/bin"
jmahhh
2016-10-07 05:53
hmmm no I didn't do that. What dir do I need to make peer in?
vigneswaran.r
2016-10-07 05:53
from $GOPATH/src/github.com/hyperledger/fabric
jmahhh
2016-10-07 05:54
oh I see. I didn't make `make membersrvc && membersrvc` either cause they are listed under Vagrant
vigneswaran.r
2016-10-07 05:55
fine.. but you may need peer to test CLI commands like deploy/invoke/query
vigneswaran.r
2016-10-07 05:56
You may know that both membersrvc and peer can be built as docker image or directly on the host..
vigneswaran.r
2016-10-07 05:56
In case of membersrvc, docker image is sufficient.
jmahhh
2016-10-07 05:57
ah ok
vigneswaran.r
2016-10-07 05:57
In case of peer, we may need "peer" executable on localhost also (for doing deploy, invoke, query from CLI)
jmahhh
2016-10-07 05:57
right

2016-10-07 05:57

Seems some dependency is missing (rocksdb). Not sure why.. Usually, vagrant setup takes care of installing all the required dependencies.
jmahhh
2016-10-07 06:47
I don't use actually use Vagrant. So I need it to make peer?
vigneswaran.r
2016-10-07 06:50
Then just ensure that you have rockdb (may be dev package) installed on your machine.

If we are not working inside the vagrant environment, we should take care of installing the pre-requisites.

This will install necessary packages (Go, Protobuf3 and rocks db)
jmahhh
2016-10-07 07:55
cheers, but I have no `base` in my `images`. I installed rocksdb via `yaourt` but it gives me `vendor/github.com/tecbot/gorocksdb/options.go:328: not enough arguments in call to _Cfunc_rocksdb_options_set_compression_options`. I think the package may be out of date... (Arch Linux btw)
garisingh
2016-10-07 07:58
@jmahhh - unfortunately almost every installer for rocksdb installs the wrong version
jmahhh
2016-10-07 07:58
yea thought so
garisingh
2016-10-07 07:58
the fabric currently only works with rocksdb 4.1

garisingh
2016-10-07 08:01
@jmahhh I guess it depends on how much time you want to spend installing configuring the base dependencies (likely translating from the ubuntu-based scripts) versus quickly getting up and running for development
vishalbatra
2016-10-07 08:01
any pointers?
vishalbatra
2016-10-07 08:02
@garisingh so what's the alternative?
garisingh
2016-10-07 08:03
@vishalbatra - what are you planning to do with the fabric? why not just use the Docker images?
vishalbatra
2016-10-07 08:04
we want to run peer and membersrvc as independent process in OS, which can be independently integrated/accessed from app server
jmahhh
2016-10-07 08:05
@garisingh nah I'd just love to get up and running.
garisingh
2016-10-07 08:05
why? you can essentially do the same thing by running the Docker images and using host networking rather than bridge mode
garisingh
2016-10-07 08:05
@jmahhh - so if you want to start contributing to fabric, then I'd go the Vagrant route. If you just want to start building chaincode and apps, I go the Docker route
jmahhh
2016-10-07 08:06
@garisingh ok cheers!
vishalbatra
2016-10-07 08:08
the app server runs Chaincode generator (from a given XML/SCDL) and deploys it on HL fabric. Can we run the app server outside docker and achieve this?
garisingh
2016-10-07 08:08
sure
garisingh
2016-10-07 08:09
either expose the ports for the Docker images (e.g. -p 7051:7051) or run your containers in host networking mode (--net=host)
garisingh
2016-10-07 08:09
either way the endpoints will be exposed on the host directly
vishalbatra
2016-10-07 08:09
ok
vishalbatra
2016-10-07 08:10
thanks. giving it a shot
ccooper21

@vishalbatra if you haven't figured out your installation problem, you might take a look at this https://gist.github.com/ccooper21/fb9ee6dca018885a1ced87cd5c60a935 You can use it to install Fabric directly in Ubuntu without Vagrant. I used it to deploy at AWS but it isn't really specific to that. Read the comments and you'll understand.

@abhisingh You may have to remove the files /var/hyperledger/production/*

I think, you run docker-compose up multiple times. So, the user test_vp0 is already logged in.

@abhisingh - it is possible that you ran `docker-compose up`, then stopped the containers, slightly modified the yaml (perhaps changing the peer config) and then ran `docker-compose up` again?

@xuxinlai - you might want to pull the latest source and go from there. I'd also advise modifying the Dockerfile for building the starter kit to simply do an `npm install hfc` rather than the way it works today installing/building the hfc from source
xuxinlai
2016-10-08 09:34
you mean that change FROM
-------------------------------------------------------------------
# install the hfc locally for use by the application
RUN npm install $GOPATH/src/github.com/hyperledger/fabric/sdk/node
-------------------------------------------------------------------
->to
-------------------------------------------------------------------
npm install hfc

@xuxinlai Some things to check when npm install fails.
1) whether you're behind any proxy?
If so, execute the following commands
npm config set proxy "http://user:passwd@proxy:port"
npm config set https-proxy "http://user:passwd@proxy:port"
Sometimes, proxy may not allow to CONNECT https. Then try the following too,
npm config set registry http://registry.npmjs.org/
Before re-executing "npm install", better clear partial install from the current directory (where npm install executed)
rm -rf node_modules

hi guys, is there a tutorial how I can strt the hyperledger locally? and then connect a couple of remote nodes and add something to the blockchain?
tuand

@vire, best place to start would be http://hyperledger-fabric.readthedocs.io or the .md files in hyperledger/fabric/docs

The docs will walk you through creating the network and executing the chaincode examples

Hi guys, I am creating 4 Validating peers. In the documentation it uses vpN, can I uses different name like HyperLedgerVPn. also in the consensus/pbft config.yaml if I have one noneVP, do I change it from 4 to 5? Thnaks
tuand
2016-10-08 19:23
For now, you have to name the peers as VPn
tuand
2016-10-08 19:25
As part of the new architecture work, we're looking at ways to have pbft work without worrying about the names
echenrunner
2016-10-08 19:40
another question if I have 4 servers(VP) and have chaincode running on those 4, is I envoke 1 of them. do I see all 4 running?
echenrunner
2016-10-08 19:50
and name conversion ofr nor vaildateing peer
garisingh
2016-10-08 20:09
there's no real use for a non validating peer
garisingh
2016-10-08 20:09
they are going away in the new architecture so I would not use them
garisingh
2016-10-08 20:10
in terms of executing chaincode, you would invoke a transaction against any one of the peers which then submits it for consensus and the transaction is delivered and executed by each peer
garisingh

I tried to write an explanation. If you want to be able to use the same id to connect to multiple peers, then you'll need to use the NodeSDK and/or the GRPC APIs instead of using the REST API

"It is possible that you ran `docker-compose up`, then stopped the containers, slightly modified the yaml (perhaps changing the peer config) and then ran `docker-compose up` again?" This is the comment from @garisingh. I did the same except changing the peer config file.
I think this is the main reason why we are getting this error.

@crazybit - I highly advise using the Docker images rather than trying to build thing locally on the host.

@crazybit, the guys working on fabric consensus use #fabric-consensus-dev ... PBFT nodes exchange messages and depend on receiving from enough nodes to determine consensus , no proof like PoW ... the seminal paper is `Practical Byzantine Fault Tolerance and Proactive Recovery` by Castro & Liskov

I didn't, only remembered going through that code in the past... isn't there a way of taking down a VP 1-by-1 and deleting it from rocks DB?
yacovm
2016-10-10 16:56
is there even a CLI to rocksDB?
yacovm
2016-10-10 16:58
So basically if the persistor is enabled (and is, by default)- your DB is tattooed forever with all peers you've ever seen before. a blessing and a curse.

2016-10-10 17:10
Therefore I must delete it. or accept the fact as it is.

To get every reloaded I have to bring-up a non-validating "peer" on the membersrvc server. and then copy everything on the /var/hyperLedger/production directory to each of the peer that runs the chaincode. Is there a better way of doing this? how do we deal with new enrollment?

@mint how’s ur deployment topology? If you deploy vp and chaincode together, then both will turn off after the shutdown. However, other peers will still provide the service normally.

2016-10-11 05:42
@baohua I know both will shutdown, but if the vp power on, can the chaincode startup automatically？Tks

That depends. Can u describe the deployment details?

I'm just curious. Because If the chaincode can’t be automatically startup after the vp, this vp is pointless for consensus

@baohua is there some way in net model chaincode container and vp container can run in different host?

arvin
2016-10-11 06:07
how can i config membersrvc HA in 0.6
baohua
2016-10-11 06:11
I guess there is no embedded HA support now. Not sure whether this should be implemented in fabric recently.
gengjh
2016-10-11 06:15
By my understanding, membersrvc HA support will be in 0.7. At least in the original milestone plan.
arvin

@gatb27 uploaded a file: https://hyperledgerproject.slack.com/files/gatb27/F2MMZ08G3/-.txt and commented: Hi all! I'm new to hyperledger and I've a very stupid question :slightly_smiling_face: I'm following the original Fabric documentation (http://hyperledger-fabric.readthedocs.io/en/latest/Setup/Chaincode-setup/) and I think I've set up everything correctly, but I don't understand a very critical thing: how can I use the REST api to start interacting with the blockchain and use some chaincode?
Do you know another guide step by step for starting to better understand how to work locally with the hyperledger?
Thanks to all which will help me, Have a goody day and enjoy your time :slightly_smiling_face:
zemtsov
2016-10-11 07:27
For example, you can make a POST request from JavaScript to `http://<yourhost>:<port>/chaincode` and send JSON you provided. This should deploy you chaincode to the blockchain.
zemtsov
2016-10-11 07:28
But you should set correct name in chaincodeID
arvin
2016-10-11 07:29
you must login in with jim or other users first. http://<yourhost>:7051/registrar
zemtsov
2016-10-11 07:31
in that case JSON should also include secureContext property, I guess

Hello. I use node.js `hfc` package to make some configuration of the blockchain. And when I call function `enroll(username, password, cb)` I get the following error:
`Handshake failed with fatal error SSL_ERROR_SSL: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number.`
Is it something in my peer config or in membersrvc config?

Hello, when i use “stub.GetRow()” to query a row in chaincode, if have not the row, an error will occurr "Error when querying chaincode: Error:Failed to execute transaction or query(Timeout expired while executing transaction)” , and can’t get the return error of “stub.GetRow()”. Why? How can i do?
yls
2016-10-11 11:12
How to ignore this errors or catch the error *in chaincode*?
vigneswaran.r
2016-10-11 11:19
@yls I think, timeout is due to other problems (not due to stub.GetRow(). Could you please check without calling GetRow() inside Query -- instead just return something hardcoded?
yls
2016-10-11 11:22
@vigneswaran.r Thanks. I tried, i found if no row the error occurred; if have the row, it’s ok.

A quick reminder: the ports have changed when moving from fabric v0.5 to v0.6. Be sure to take the correct actions when communicating with your fabric peers.

@echenrunner not sure what you mean by 'the old block'? Is the chain height less than on the other peers ?
tuand
2016-10-12 02:54
How many invokes were done ? As long as there are transactions coming into the network, the lagging peer will recognize that it is behind and initiate state transfer to catch up.
tuand
2016-10-12 02:56
Also the v0.6 version of hyperledger fabric had a fix for a condition where state transfer was stuck

Hey possibly a silly question: How does inter-chain validation work? If, for instance, I was an entity A with my own HLF block chain and wanted to handle an asset from entity B who had their own HLF block chain, how would I assemble this transaction and be able to validate it on my own A chain? Maybe is there be a way to delegate peers between chains to ensure that if the other B network goes down I can still check that all the transactions on the other ledger are kosher? In other words how do I link a bunch of sub-chains and ensure any transactions between them are valid?

2016-10-13 10:52
@pushpalatha - unfortunately, you actually need to "vendor" your external dependencies including the fabric. In the root of your chaincode source folder, create a folder name `vendor`. You can then either use a tool like `govendor` to install the dependencies in the `vendor` folder or simply copy/clone the packages into `vendor`. The structure needs to match what would be under `$GOPATH/src` - e.g.
`vendor/github.com/hyperledger/fabric`
`vendor/github.com/op/go-logging` (although this is actually vendored in the fabric so might not need this)

The chaincodes call each other, and I've ensured an ordering during deployment too.
Any pointers as to what could be going on here?

@chaitanya do your chaincodes call each other on deploy? You said there was an ordering for deployment but it looks like one of the chaincodes is being called before deployment is finished on that peer, just from the messages you have posted. If there is an order for deployment where all of them deployed in order? at what point are you failing?

2016-10-13 14:32
Chaitanya, try increases value of timeout in the in the "consensus/pbft/config.yaml" I used to get that message now is gone. P.S I have no ideal what I did. :slightly_smiling_face:

in my case , rootnode need connet other three.like this in one vp config CORE_PEER_DISCOVERY_ROOTNODE=10.10.33.85:7051,10.10.33.86:7051,10.10.33.87:7051.
# Peer discovery settings. Controls how this peer discovers other peers
discovery:
# The root nodes are used for bootstrapping purposes, and generally
# supplied through ENV variables
# It can be either a single host or a comma separated list of hosts.
rootnode:
"It can be either a single host " just config one rootnode,i can't understand ,who knows about that case?

if so, easiest thing is to simply use the Docker images with Docker Toolbox or Docker for Windows (if using Windows 10)

tom.appleyard
2016-10-14 13:18
@echenrunner So I've downloaded the docker containers based on the instructions on the readthedocs site.
I have an hfc app that I have used to deploy chaincode onto peers when they run natively and I'm trying to get the two to speak and to get some chaincode deployed and then a query invoked

Chaitanya, If this condition does occurs, you need to issue "peer node stop" on the offender VP that want down without being "Deregistered" to the other peer(s). The "stop" will tells the other peers is being "Deregistered" - transport is closing from the handleChat . Then bring it back up, the message should be gone.

I am currently trying to document crypto mechanisms involved in Fabric in different areas and processes of the ledger activity. I was sweeping through the source code in /master/core/crypto and I found references to : (1) client_confidentiality.go (2) node_tca.go (3) hash.go (4) ecdsa.go (5) x509.go. There's more references to cryptographic mechanisms in /fabric/core/crypto. Unfortunately, none of these pieces of code are documented or commented and therefore, I do not know what they serve for and in what order should I analyze them. Can anyone help me understanding what is used and when?

Hi Everyone. Is there a road map for Java code support updates. Its quite long since updates happened on the Java Shim Packages

Hi guys just a small query. Is it possible to query based on timestamp or block number and retrieve the old block key value? I had read in a documentation that it is a work in progress.

Hey All, would someone be able to explain using tables to me?
Specifically - when you make a table I get the idea that you specify the columns and what each column is called and contains but what does the 'key' field mean?
Likewise, when you do a search for a row in a table you do so by something like this:
```var columns []shim.Column
col1 := shim.Column{Value: &shim.Column_String_{String_: args[0]}}
columns = append(columns, col1)
col2 := shim.Column{Value: &shim.Column_String_{String_: args[1]}}
columns = append(columns, col2)
col3 := shim.Column{Value: &shim.Column_String_{String_: args[2]}}
columns = append(columns, col3)
row, err := stub.GetRow("RequestTable", columns)
```
The table the above searches contains 7 columns yet in this only 3 are specified - what is happening here? - So far as I can see what is happening is that 3 column objects are being made containing the arguments put in (I assume these arguments are values to be searched for?). However the column objects in the array don't seem to be given any kind of identifier that might link them to the columns in the table (apart from the type) as such how does the table know which column in the table to compare them to?

>when you do a GetRows/GetRow you can supply values of 0 or more key columns. you cannot specify the values of non-key columns. you have to specify the values of the key columns in the order that they are defined in the table, so if you have a table with key1, key2, key3 you cannot do a query of key3, key1, key2 - it has to be key1, key2, key3
>
>if you have multiple key columns then you have to supply all the keys that come before it in the query. for example, if you have a table with key1, key2, key3 you cannot do a query with just key3 or key2. you have to do a query with key1, key2, key3 or key1, key2 or key1.
>
>this is because the rows in the table are mapped into key/value pairs and the key is basically tableName+(concatenated values of key columns)

Hello. I’m starting 4 peers and a membersrvc with `docker-compose up` command. Then I register the user `user1` and enroll it with the provided password from JS via HFC API.
After it I try to check the result via REST API using the endpoint `http://localhost:7050/registrar/user1`. The response is ```{
"Error": "User user1 must log in.”
}```
I try to send enrollId and enrollSecret to `http://localhost:7050/registrar` and get this response: ```{
"Error": "rpc error: code = 2 desc = Identity or token does not match."
}```
What is wrong in my scenario?
garisingh
2016-10-21 11:21
likely you have some leftover credentials from a prior use of the SDK? Try deleting `/tmp/keyValueStore` and running again

should it be enough?

OH
garisingh
2016-10-21 11:23
sorry
garisingh
2016-10-21 11:23
let me get this straight
zemtsov
2016-10-21 11:23
when I use REST API I don’t use it , I believe
garisingh
2016-10-21 11:23
1) are you enrolling via hfc?
zemtsov
2016-10-21 11:23
1) yes
garisingh
2016-10-21 11:25
ok - so let me try to explain (and apologize if you know all of this)
zemtsov
2016-10-21 11:26
(I’m sure I don’t understand how exactly it works)
garisingh
2016-10-21 11:29
- You can enroll a user once as the enrollSecret is a one time password.
- The Node SDK (hfc) and the REST API actually take different paths in how they work
- The NodeSDK will enroll you and download the credentials locally (default is `/tmp/keyValueStore`). At this point, you are enrolled (so you can't enroll again) but your credentials are local to the SDK and now you can only use the SDK to invoke/query as the enrollID you used to enroll
- The REST API works differently. We you call the `/registrar` endpoint via REST, what happens is the the peer actually acts as a "wallet" and enrolls you behind the scenes. So in this case, the credentials end up being stored on the peer itself (by default in the `/var/hyperledge/production/client` directory and in your case this would be inside the Docker container)
garisingh
2016-10-21 11:30
so the bottom line is that if you enroll via HFC you can't use the ID via the REST API and vice versa - if you enroll via the REST API you can't use that ID via HFC
garisingh
2016-10-21 11:30
hopefully this (somewhat) makes sense
zemtsov
2016-10-21 11:31
So, before I work with the system I should choose the way I’ll do it: HFC or REST?
garisingh
2016-10-21 11:32
you got it - you need to choose REST of HFC for any given enrollID
zemtsov
2016-10-21 11:32
Thank you! That was very helpful
zemtsov
2016-10-21 11:35
And if I enroll a user on my host machine, its credentials are saved locally. Can they be used only from my host machine? Can they be used by a script running from another machine in the network?
garisingh
2016-10-21 11:36
well the credentials will physically be on your host machine by default when using the SDK, but it is possible to store the credentials in a database (you'd need write a plugin) which could be access from multiple machines.
zemtsov
2016-10-21 11:39
What about user’s certificates?
zemtsov
2016-10-21 11:40
is there any difference how certificates are used via HFC and REST?
garisingh
2016-10-21 12:03
interesting question - the answer is yes and no. With HFC, the certificates are directly used within the hfc code - meaning you'll actually be submitting signed transactions via GRPC to a fabric peer (and technically you could control usages of trasnacaction certificates, etc). When using the REST API, the crypto functions are delegated to the peer to act on your behalf (so you submit a REST call with SecureContext in it and then the peer takes that, converts it into a fabric transaction, signs it with the credentials it is storing on your behalf and then submits it)
garisingh
2016-10-21 12:04
So in the end, the system will see the same certificates either way, just that HFC is a more direct and controlled path for a client
zemtsov
2016-10-21 12:06
And from the chaincode’s point of view they are the same, right?
garisingh
2016-10-21 12:07
correct
zemtsov
2016-10-21 12:07
Thank you very much!
garisingh
2016-10-21 12:08

Hello guys,
If maybe someone could help me out:
I have a private peer network running on 4 virtual machines. 5th machine has membershipservice running on it.
In order to perform requests to any of those peers i need a certificate.
On Bluemix, we have a link in variables: "cert": "https://blockchain-certs.mybluemix.net/us.blockchain.ibm.com.cert"
When setting up a local network, how to get that certificate? Does membershipservice provide it somehow, or should i generate it in some way?
Many thanks!

@echenrunner yes, i have my membersrvc.yml and core.yml setup
garisingh
2016-10-21 14:34
yes - sorry - for the fabric. It's a bit tricky in that there is a "chicken and egg" problem if you try to use the TLS certificates issued by membership services since you have to start the peer without TLS, have it contact membership services to get its TLS certificate and then start it in TLS mode
garisingh
2016-10-21 14:36
For Bluemix, we actually circumvent this as we actually wanted to use a certificate signed by a public CA (we used Digicert). So we actually use a wildcard certificate (for *.http://us.blockchain.ibm.com) and configure all of the nodes to use that certificate and then we also create the proper DNS entries as well
garisingh
2016-10-21 14:37
so we pass PKIX validation and hostname verification
garisingh
2016-10-21 14:37
are you interested in doing this more for demonstration purposes or are you really trying to get something securely deployed?

Hi everyone. I am a newbie here. Can somebody help me understand how to contribute to Requirements Working Group on different use cases. Best Abhishek

2016-10-23 06:01
Hi @agupta2016, I can point out a few URLs that you can follow. First, that WG is part of the Public Meetings (Calendar): https://wiki.hyperledger.org/community/calendar-public-meetings#requirements_wg
jonathanlevi
2016-10-23 06:02
Second, there is also a lot of (general) info in the wiki (e.g., https://wiki.hyperledger.org/community/frequently-asked-questions-faq)
jonathanlevi
2016-10-23 06:04
But more specifically, the easiest will probably be to write to Oleg Abdrashitov (who is very friendly!) directly (before, after or during one of these meetings)...
agupta2016
2016-10-23 06:44
Thanks a lot @jonathanlevi for the links. Also Thanks for pointing me to Oleg. I am keen to contribute to use cases described at https://github.com/hyperledger/hyperledger/wiki/Requirements-WG . Hope these meetings point me to that too.

@sumitks - where in your config is port 5005?
garisingh
2016-10-24 09:45
also, how are you running the peer?
sumitks
2016-10-24 09:48
@garisingh I am running the peer with security and privacy disables using the procedure available at : https://hyperledger-fabric.readthedocs.io/en/latest/Setup/Chaincode-setup/#running-the-chaincode. I have been able to make peer but encountered the error while running the command start peer node.
garisingh
2016-10-24 09:49
so you are running `peer node start` and getting that error?
sumitks
2016-10-24 09:50
yes
sumitks
2016-10-24 09:50
i ran the code : peer node start --peer-chaincodedev
garisingh
2016-10-24 09:52
ah - shoot - I know the problem
garisingh
2016-10-24 09:53
the `master` branch has now been updated to start development on the new v1 architecture
garisingh
2016-10-24 09:53
what you'll need to do is to checkout the `v0.6` branch instead. better yet, you may just want to run the Docker images we have built for v0.6.1-release-preview
sumitks
2016-10-24 10:01
@garisingh can you elaborate a bit... i am a fresher in this field. Currently playing out with docker toolbox and vagrant on my windows 7 to develop local environment for experimenting with block chain.
Didnt get what u meant with checking out version the new updated master branch 0.6?? I however downloaded the latest images and tired building peer in the non-vagrant environment. But I could not locate the peer using the address 127.0.0.1:2375.
sumitks
2016-10-24 10:02
sorry the address is 172.17.0.1:2375
garisingh
2016-10-24 10:05
sure - so a couple of points:
1) The documentation was written for the `v0.6` version of the fabric which is the latest stable release.
2) Over the past few days, we've been "merging" `v1.0` feature branches into the `master` branch of the repository so if you clone the source repository the `master` (default) branch will actually be for `v1.0` which means that things no longer work exactly as they did in `v0.6` (and as the docs describe)
Is it safe to assume that you are more interested in using the fabric and developing chaincode and applications rather than actually doing development on the core fabric code itself?
garisingh
2016-10-24 10:08
be right back ....
sumitks
2016-10-24 10:10
@garisingh yes actually I am trying to learn building a chain code first. Can you help me out with some links for the chain code development. and are the command for cloning v0.6 and v1.0 different?

@sumitks - I'm back. So hopefully what we can do here is get you up and running with the Docker images and then developing / running your chaincode on your Windows 7 host.
Step 1: Install Docker Toolbox for Windows (I think you did this already)
Step 2: Use the "Docker QuickStart Terminal" shortcut (either on your desktop or via the start menu) to launch Docker on your Windows host (if you've done this already, I'd recommend closing any open "QuickStart Terminal" Windows
Step 3: After launching the "QuickStart Terminal", you'll see a line printed out underneath the Docker picture - something like `...configured to use the default machine with IP http://XXX.XXX.XXX.XXX` - you will want to capture that IP address as we'll need it when we run the chaincode later
Step 4: Follow https://hyperledger-fabric.readthedocs.io/en/latest/Setup/Chaincode-setup/#option-3-docker-toolbox to create a compose file and launch the peer and membership services
garisingh
2016-10-24 10:47
Step 5: If you don't have Go installed on your Windows host, install that next

@garisingh I have run the command docker-compose up and got the following response

the image above
garisingh
2016-10-24 11:02
ok - good looks like things are working up until now
garisingh
2016-10-24 11:02
do you have Go installed on your Windows host?
sumitks
2016-10-24 11:03
yes
garisingh
2016-10-24 11:05
(I'm going to write out some additional steps which you might already have done but hopefully we can capture these for others to use as well)
garisingh
2016-10-24 11:17
Step 6: Launch another "Docker QuickStart Terminal"
Step 7: In that terminal, `cd $GOPATH/src` (if GOPATH is not set, refer to the Golang instructions on setting up your GOPATH - https://golang.org/doc/install
Step 8: run `mkdir -p http://github.com/hyperledger`
Step 9: `cd http://github.com/hyperledger`
Step 10: `git clone -b v0.6 --single-branch http://gerrit.hyperledger.org/r/fabric`
Step 11: `cd fabric/examples/chaincode/go/chaincode_example02`
Step 12: `go build`
Step 13: `CORE_CHAINCODE_ID_NAME=mycc CORE_PEER_ADDRESS=http://XXX.XXX.XXX.XXX:7051 ./chaincode_example02` - replace http://XXX.XXX.XXX.XXX with the IP address you capture in Step 3
garisingh
2016-10-24 11:17
if this works ( :pray: ) then you should be able to develop your own chaincode locally on your Windows host as well
garisingh
2016-10-24 11:19
you'll just want to make sure that you emulate Step 13 but replace `chaincode_example02` with your compiled chaincode - you can also of course give it a different name by passing a different value for `CORE_CHAINCODE_ID_NAME`
garisingh
2016-10-24 11:19
(note that Step 10 above is a convenient way to ensure that you only have the v0.6 version of the src code in your GOPATH)

@sumitks did you try CORE_PEER_ADDRESS=127.0.0.1:7051
muralisr
2016-10-24 13:16
also make sure 7051 is up with `netstat -an`

@muralisr i didn't get what you mean with netstat -an
sumitks

If you mean including 7051 in the compose file then it is already included in it

my core peer address was my vm ip:7051

it is not working with either of the core peer addresses

sorry - was away - not sure what is going on. Can you run the following commands in the same quick start terminal window you are using:
`docker run --rm --net host -it alpine /bin/sh`
garisingh
2016-10-24 13:35
once that runs, it you should be in another shell
garisingh
2016-10-24 13:36
then run
`ifconfig eth1` and check the ip address
garisingh
2016-10-24 13:37
also run
`netstat -an |grep 7051` and make sure you get something back

```
After you have placed your chaincode project under the $GOPATH/src, you will need to vendor the dependencies. From the directory containing your chaincode source, run the following commands:
go get -u http://github.com/kardianos/govendor
cd $GOPATH/src/github.com/chaincode_example02
govendor init
govendor fetch http://github.com/hyperledger/fabric

did you pull the base image or did you try to trick of re-tagging the peer image? looks like the latter but just want to make sure

Looks like ` src/build-chaincode/vendor/github.com/hyperledger/fabric/peer/core.yaml` is missed inside the image. Should I install govendor inside the image?

I do “vendor” my chaincode. After that a new `vendor` directory appears. Inside it I can find all dependencies from my chaincode. But when I deploy the code to the blockchain I get this error:

it is better to use the node SDK than the REST api

ok , but i don't know whether a test node.js app is available in the documentation for testing the deployment of chaincode. still can you give me instructions for both Rest Api and Node Sdk?, i am relatively fresher here.... @yacovm ......and for rest api we need to build vagrant environment right?? or can it be done using docker also.

how i can check if the peer started or not ?
wlahti
2016-10-25 15:34
I believe that running ‘docker ps’ should give an indication of the whether the peer is running no matter which method you choose to run the peer (e.g. vagrant, docker-compose)

I'm try to verify " state may be inconsistent, cannot query" by bring down one of my validating peer. after the peer comes back up from the outage, I did a query and it still has the old ledger. and I can't found any messages in the logs that indicate that the peer i'm querying be "inconsistent".
tuand
2016-10-25 16:04
@echenrunner I'm assuming you're running a PBFT network of at least 4 peers ... are you sending transactions to the network after you restarted your peer ? that peer won't know it is lagging unless it is receiving checkpoint messages from the other peers ... we can continue the discussion to #fabric-consensus-dev

```07:07:25.908 [dockercontroller] Start -> ERRO 01c start-could not start container API error (500): {"message":"oci runtime error: process_linux.go:245: running exec setns process for init caused \"exit status 1\""}

Hy just question i have to install java to execute examples ??
ahmedelhajji
2016-10-26 10:53
and which version i have to use
garisingh
2016-10-26 11:01
Java is only needed if using Java chaincode. Java8 is what we use (openjdk 8 but oracle or ibm java 8 should both work as well)
sumitks
2016-10-26 11:04
can we use CLI to deploy chain code with docker images instead of vagrant (windows 7)??
sumitks
2016-10-26 11:05
or is vagrant environment necessary to do so
garisingh
2016-10-26 11:20
I don't see why not. I typically use either hfc or REST, but the CLI should work as well as long as you configure the target endpoint correctly
sumitks
2016-10-26 11:22
actually i am getting an error:
sumitks
2016-10-26 11:23
@sumitks uploaded a file: https://hyperledgerproject.slack.com/files/sumitks/F2UD08KGS/capture5.png
sumitks
2016-10-26 11:23
i have run the command: docker ps and it shows running peers
sumitks
2016-10-26 11:24
in the documentation it is written that you need to run vagrant ssh before running the command as in the snippet
sumitks
2016-10-26 11:25
or are the commands for docker different than vagrant

garisingh
2016-10-26 11:28
so if you run Docker only, you won't have the peer binary installed locally. So you'll need to `exec` into your peer container:
`docker exec -it [CONTAINER NAME OR ID] /bin/bash`
garisingh
2016-10-26 11:29
then you should be able to run the peer command from within there
sumitks
2016-10-26 11:30
ok thanks will try it out

Hi all,
I have a question regarding deploying chaincode. When I run this:
$ peer chaincode deploy -p http://github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02 -c '{"Function":"init", "Args": ["a","100", "b", "200"]}'
I get the following error:
Error: Error endorsing chaincode: rpc error: code = 2 desc = Failed to init chaincode(handler not found for chaincode 1f5168d3a4a42b50fc25af0743bb9924bc49332cfe295384b211214b4d32cedbb488bf8da775fcd84db2b5a77d3ad91bd134f9ee2dc22f1d0e9d4515110df21f)
Does anybody have an idea of what might go wrong?
garisingh
2016-10-26 11:47
@damiang - are you running in chaincode dev mode?
damiang
2016-10-26 11:47
yes
garisingh
2016-10-26 11:51
so you'll need to compile and run the chaincode as an executable: https://hyperledger-fabric.readthedocs.io/en/latest/Setup/Chaincode-setup/#not-vagrant
damiang
2016-10-26 11:51
ok thx, I'll try to do this
garisingh
2016-10-26 11:52
and then you'll want to do something like:
`peer chaincode deploy -n mycc -c '{"Args": ["init", "a","100", "b", "200"]}'`
garisingh
2016-10-26 11:53
notice that the `-n` here needs to match the value you use for `CORE_CHAINCODE_ID_NAME` like here https://hyperledger-fabric.readthedocs.io/en/latest/Setup/Chaincode-setup/#starting-and-registering-the-chaincode
damiang
2016-10-26 11:59
I still get an error:
$ peer chaincode deploy -n mycc -c '{"Args": ["init", "a","100", "b", "200"]}'
11:57:30.859 [devops] GetChaincodeBytes -> ERRO 001 Error getting chaincode package bytes: Cannot generate hashcode from empty chaincode path
Error: Error getting chaincode code chaincode: Error getting chaincode package bytes: Cannot generate hashcode from empty chaincode path
Actually I had this before, this is why I used -p ...
muralisr
2016-10-26 12:07
@damiang if you are using the “-n” param with deploy, you need start peer in `—peer-chaincodedev` mode AND `go build` and start the chaincode yourself to have it registered with the peer before issuing the deploy command
muralisr
2016-10-26 12:07
in other words, “-n” with deploy is meant only for —peer-chaincodedev mode
damiang
2016-10-26 12:09
I started the peer in `--peer-chaincodedev` mode, but it still doesn't work..
muralisr
2016-10-26 12:10
did you start the chaincode … something like this `CORE_PEER_ADDRESS=127.0.0.1:7051 CORE_CHAINCODE_ID_NAME=mycc ./chaincode_example02`
muralisr
2016-10-26 12:11
the above assumes you are using vagrant but the point is that chaincode has to be started and registered with the peer in dev mode
damiang
2016-10-26 12:15
I have three terminals. In the first, I run a peer with `peer node start --peer-chaincodedev`
In a second, I run `CORE_CHAINCODE_ID_NAME=mycc CORE_PEER_ADDRESS=0.0.0.0:7051 ./chaincode_example02`. This shows "Received REGISTERED, ready for invocations"
In the third, I run `$ peer chaincode deploy -p http://github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02 -c '{"Args": ["init", "a","100", "b", "200"]}'`,
and this yields "Error: Error endorsing chaincode: rpc error: code = 2 desc = Failed to init chaincode(handler not found for chaincode 1f5168d3a4a42b50fc25af0743bb9924bc49332cfe295384b211214b4d32cedbb488bf8da775fcd84db2b5a77d3ad91bd134f9ee2dc22f1d0e9d4515110df21f)"
muralisr
2016-10-26 12:25
so you are using the latest master.
muralisr
2016-10-26 12:26
it was tested for —peer-chaincodedev mode but did not try it recently
muralisr
2016-10-26 12:26
let me check it and get back to you soon @damiang
damiang
2016-10-26 12:26
so you think I should try another version?
damiang
2016-10-26 12:26
Ok thank you, very much appreciated!
muralisr
2016-10-26 12:26
master is WIP for v1.0 … to get the full feature I’d try the 0.6
muralisr
2016-10-26 12:27
one thing
muralisr
2016-10-26 12:27
to make the above work in master you’d also have to start the orderer
damiang
2016-10-26 12:28
I don't necessarily need to have it work in master..
What do you mean by orderer?
muralisr
2016-10-26 12:30

Hello, I have a question on adding new peers. Right you have to bounce all peers when adding a new one, is it going to possible to add new peers in V1.0 without restarting all peers (endorsers/commiter/Consenter). Can you tell which features sets in JIRA address it. Found this in JIRA site but want to check what other specific JIRA FABs address this requirement. https://jira.hyperledger.org/browse/FAB-37
tuand
2016-10-26 13:02

Where does bluemix intersect with hyperledger ? Or, maybe it collides ?
lanzen
2016-10-26 14:32
@kent_landholm I’m early in the learning process, but here’s my take. Hyperledger is the open source project that IBM is participating in. It is the foundation of the IBM Blockchain service. So if you go to Bluemix and provision the IBM Blockchain, you’re running on top of Hyperledger.
jasondotstar
2016-10-26 14:34
Can you suggest a development workflow for contributing to Hyperledger?
lanzen
2016-10-26 14:53
IBM is managing a fork of Hyperledger from which I assume it feeds changes, as PRs, into the public Hyperledger. They are managing work items and the like for upcoming changes, so they could be building what you’re thinking of already. Alternatively, you could fork the project, build your changes and then submit them to the public Hyperledger as a PR.

"The plan going forward is to remove the REST API from the peer entirely and instead, to transition all of the functionality provided by the REST API into the SDK packages. At this point, the REST API is still in the code base, but not under active development. If there are any critical bugs, we address those. But that is it. So if you are just now getting started with the fabric project, I would only recommend using the REST API in order to get familiarized with the different features and some quick testing. For any application code, please use the Node.js SDK. I honestly do not know anything regarding the Java SDK or the Python SDK, but I do not believe they are ready for consumption at this point.

Can someone help me on IBM Bluemix question.. There is BlockChain services on their Public Bluemix .. We are internal and have a Dedicated IBM Bluemix that does not have Blockchain services. Anyone know if there are plans to have this service internal .. or how can we install the fabric ourselves
bfuentes
2016-10-26 16:10
@jvescio I think all services on dedicated should be able to access to all public services. As this services are hosted outside somewhere, something have to be configured I guess. I never had a look on it. For self installation, please foolow official Hyperledge Fabric docs here : http://hyperledger-fabric.readthedocs.io/

@tom.appleyard - I believe the mockstub was only added in v0.6. One change between 0.6 and 0.5 is that in 0.5 a pointer to the stub was passed in whereas in 0.6 we pass the actual value in which allows us to do mock testing

@garisingh working on a project based on this boilerplate:
https://github.com/IBM-Blockchain/fabric-boilerplate
which uses 0.5 and we need a way of doing unit testing. So far we've found this as a possible basis for how to do it, other than that we could also just stand up a peer and target the chaincode at it
https://github.ibm.com/IBM-Blockchain/trade-finance/tree/master/code/chaincode
Any suggestions if there's a better approach?

@abhisingh run the command echo "DOCKER_OPTS=\"-s=aufs -r=true --api-cors-header='*' -H -H unix:///var/run/docker.sock \"" > /etc/default/docker and then restart the service
abhisingh
2016-10-27 16:03
Ok. Let me try this.

@abhisingh has this every worked? The daemon has to be started as root. What distro are you on? You can type: ps -ef | grep docker ..if you see nothing than the daemon is not started. If you see something it will show what user it is running as. Here is a good link: https://www.digitalocean.com/community/tutorials/how-to-install-and-use-docker-getting-started
abhisingh
2016-10-27 17:04
Command given by @nagasurya solves the problem.
bmos299
2016-10-27 17:06
@abhisingh great. did you get this issue addressed, ""Error building images: Tag latest not found in repository http://docker.io/hyperledger/fabric-baseimage"
bmos299
2016-10-27 17:09
you can actually use the peer and tag it as the baseimage. i can give you an example.
abhisingh
2016-10-27 17:09
I pulled x86 tag hyperledger/fabric-baseimage and then tag it as latest
bmos299
2016-10-27 17:10
ok
bmos299
2016-10-27 17:10
great
bmos299

abhisingh
2016-10-27 17:10
This is same right?
bmos299
2016-10-27 17:10
yes. the deploy should work.
abhisingh
2016-10-27 17:10
Yes. Thanks alot :slightly_smiling_face:
bmos299
2016-10-27 17:10

bmos299
2016-10-27 17:10
are you using docker-compose or starting a single peer?
abhisingh
2016-10-27 17:10
Yes. It is working but I am getting some error while registering some user.
abhisingh
2016-10-27 17:11
Starting a single peer using docker-compose with membersrvc
bmos299

wale
2016-10-28 16:47
installing docker for the hyberledger fabric on a mac . Installation is still going, 2 hours in. Is that normal?
lanzen
2016-10-28 17:34
When using HFC to build a solution with Node, is the expected development environment to have the chaincode be included in the overall Node project? Think of it from the perspective of managing the project in GitHub. Or, is the expected environment to have 2 separate GitHub projects: one for the Node code and a second for the chaincode?
lanzen
2016-10-28 17:35
I ask because it looks tricky how HFC exposes a deploy() interface that takes a chaincodePath which gets (hardcoded) appended to the end of $GOPATH/src/.
tuand
2016-10-28 17:38
@lanzen, i don't have the answer to your question but the sdk developers use #fabric-sdk-node and #fabric-sdk-node-dev .

can you try to run the example with the membership service and try again?

so I should start 4 noops first and then 4 PBFT with member services?
yacovm
2016-10-29 06:47
no no

2016-10-29 06:48
or just the docker-compose -f docker-compose-with-membersrvc.yml up

just use the docker-compose file

rick.behl
2016-10-29 07:22
is it a simple change to the yaml?
yacovm
2016-10-29 07:22
depends. you want SSL between the peers?
rick.behl
2016-10-29 07:24
if possible
yacovm
2016-10-29 07:27
I can give you a docker-compose file with SSL enabled and security enabled that I made but you'll have to make a self-signed certificate for that to work. I'm not sure how to make one that satisfies the peers though. What I do for testing is take the files from the chaincode certificates and plant them in the right place and then it works.
Even then, I can't assure you that'll work 100% with what you need, because I have no clue in the fabric flow of the whole user registration thing, as stupid as it sounds, I never tried doing that (I'm not a user, I'm a developer and I focus in the peer communication layer and a specific component in the next architecture)

garisingh
2016-10-29 10:40
hi @jmahhh - I see the problem(s)
garisingh
2016-10-29 10:41
1) you actually have the wrong path - your path should be `https://github.com/jmahhh/learn-chaincode/finished`
BUT
garisingh
2016-10-29 10:42
then you will run into a second issue which is that the tutorial in the BMX docs has not been updated to reflect the changes in the learn-chaincode repository either
garisingh
2016-10-29 10:43
there are currently 2 versions of the fabric which people are using:
v0.6 (the latest and available via Docker image from Docker hub)
v0.5 - previous version which is actually what is running in BMX (we'll be updating BMX in the next 2 weeks)
garisingh
2016-10-29 10:44
unfortunately the chaincode interface changed between v0.5 and v0.6 so we had to update learn-chaincode to support both
garisingh
2016-10-29 10:45
the end result is that the URL you'll want to use for your path is actually `http://gopkg.in/jmahhh/learn-chaincode.v1/finished`
garisingh
2016-10-29 10:46
if you check out https://github.com/jmahhh/learn-chaincode#deployment you'll see the explanation of why we are using `http://gopkg.in` here is the path
garisingh
2016-10-29 10:46
FYI - I was able to deploy the chaincode to my network using `http://gopkg.in/jmahhh/learn-chaincode.v1/finished`
garisingh
2016-10-29 10:47
this also means that if you want to make any changes, you should do it on the `v1.0` branch of your fork
garisingh
2016-10-29 10:47
hope this helps

@mano, no websocket per se but take a look at the eventing example at hyperledger/fabric/examples/events/block-listener https://gerrit.hyperledger.org/r/gitweb?p=fabric.git;a=tree;f=examples/events/block-listener;h=9b3043d625e07ec4935a212b3acf24df4f5d66fe;hb=HEAD

Hi, I try to follow the changes on fabric from my old days.
I found the configuration of pbft and noops probably now merged to kind of orderer.
I have 2 questions
1. Can anyone confirm if my guesses are right?
Noops Block Size --> Batchsize
Noops Block Timeout --> BatchTimeout
PBFT general mode --> ? (cannot find where it is in this current version, probably all become batch mode)
2. Any reason to move to orderer? And what's differences btw solo and kafka mode for orderer?
stylix
2016-10-31 02:56
Extra question
3. How to config orderer.yaml correctly using environment variable?
Are the following ENVs are correct?
e.g.
CORE_COMMITTER_BATCHTIMEOUT
CORE_COMMITTER_BATCHSIZE
CORE_COMMITTER_XXX
mint
2016-10-31 07:28
@cbf @baohua Here is a tough situation, at the beginning, I seted up 4 peers with pbft, then I deployed a chaincode on one of the peers, all the other 3 peers can deploy the chaincode automatically of course. But now, I set up a new peer which the core.yaml config set rootnode with one of the 4 peers addr, I think the chaincode can also be deployed on this peer automatically, but unfortunately not. Does HF can do that at version 0.6? Thank you!

No, the pbft mode does not support this dynamic node adding situation.

@mint we expect to have the ability to dynamically add endorser nodes by v1.0. The set of orderer nodes will be fixed initially, but we hope to get to dynamic addition once we have introduced checkpointing (post 1.0 IIRC).

Hey All, the `tx.on('complete', function(results){ ... })` that we have in HFC, currently mine keeps coming up with `{"result": "waited 5 seconds and assumed invoke was successful"}` is there any way to turn this off and make it return upon the invocation actually completing?
Thanks!
tom.appleyard
2016-10-31 15:05
Re: the above
So from asking around this is something you can only change with 0.6 where you can use the `chain.eventHubConnect()` function to make the callbacks actually happen with their namesakes. If you want this functionality in 0.5 it looks like polling is the only option :confused:

Something seems to be the issue with stub shim.ChaincodeStubInterface
zemtsov
2016-11-01 08:25
As far as I know `Init(shim.ChaincodeStubInterface)` is the new interface. 0.6 wants function and arguments passing as separate parameters to functions Init, Query and Invoke.
jmahhh
2016-11-01 08:27
so is `GetFunctionAndParameters` 0.5 then?
jmahhh
2016-11-01 08:28
I thought it was the other way around
zemtsov
2016-11-01 08:32
@jmahhh `GetFunctionAndParameters` is in the master branch: https://github.com/hyperledger/fabric/blob/master/core/chaincode/shim/chaincode.go
but there is no such function in v0.6:
https://github.com/hyperledger/fabric/blob/v0.6/core/chaincode/shim/chaincode.go
jmahhh
2016-11-01 08:33
hmmm ok

rishavkmr09
2016-11-01 12:28
When running Docker natively on Mac and Windows, there is no IP forwarding support available. Hence, running more than one fabric-peer image is not advised because you do not want to have multiple processes binding to the same port. For most application and chaincode development/testing running with a single fabric peer should not be an issue unless you are interested in performance and resilience testing the fabric’s capabilities, such as consensus
zemtsov
2016-11-01 12:32
@rishavkmr09 you can make a correct port forwarding for every image and run several peers. I can show the example of docker-compose file if you want

wrt to the above docker-compose file.. can I ask why links are only made to vp0? does vp0 have a special property that links all of them together? and would it be incorrect or unnecessary to also link to vp1 & vp2 from vp3
zemtsov
2016-11-01 17:07
@pd93 without `CORE_PEER_DISCOVERY_ROOTNODE` you’ll see only one peer from `http://<node_addr>:7050/network/peers`. So, my guess is the role of vp0 is to make all peers know about each other. I’m sure somebody here can give you deeper answer.

you either need to download the `fabric-baseimage` and retag it to `latest` or you could just retag the peer image you already have as `hyperledger/fabric-baseimage:latest`

ah - in this case the issue is likely that you are going to need to add the fabric source to a vendor folder in the directory with your chaincode

For the invoke, should I still use REST to accept a very large data as a Based64, e.g. 100mb?
I'm finding some way else if I should not do REST invoke.

@stylix suggest you look at using the SDK rather than REST ... see #fabric-sdk-dev and #fabric-sdk-node-dev
stylix
2016-11-02 12:57
Actually, I may need REST for some period of time.
BTW, for SDK, can I run it without a membership service?
stylix
2016-11-02 12:58
Since I actually don't need that membership for the moment, but it seemed the sdk use that, mostly.
tuand
2016-11-02 13:00
past my level of expertise :grin: I have to redirect you to the sdk slack channels and to the wiki https://wiki.hyperledger.org/community/fabric-design-docs
stylix
2016-11-02 13:10
Well, maybe my knowledge also wrong with SDK, I will check it.
stylix
2016-11-02 13:10
BTW, thank @tuand for this.

Is there a problem with using 0.5.4 instead of 0.5.3 hfc (sdk for nodejs) for Bluemix Blockchain - its the way I found for resolving the secure handshake error.

@mano to solve the http2 http1 error .. u need to adjust the chain setup to chain.setMemberServicesUrl("grpc://"+MEMBERSRVC_ADDRESS);
chain.addPeer("grpc://"+PEER_ADDRESS);
instead of putting the actual IP :
MEMBERSRVC_ADDRESS and CORE_PEER_ADDRESS are set in the docker-compose file

Regarding how tables work in Hyperledger can anyone explain to me _why_ they are are set up like this - I mean what advantage is there to not allowing the user to specify an arbitrary key and search on it and forcing them to do `GetRows()` with a linear combination of them?

I have a "4 peers" blockchain network with pbft consensus (vp0, vp1, vp2, vp3). I used postman (to generate post REST API) to deploy a chaincode (chaincode_example02, A=100, B=200) in to this network, and get more 4 containers that run my chaincode.
I call Invoked transaction to vp0 to get the result like this (A-5, B+5 => A=95, B=205).
Then, I requested QUERY to vp3 to get A value. I got A=95. It's OK.
And then, I stop peer vp3, and restart it. After that, I call query request to vp3 to get A value. But, I got A=100 (like after chaincode deploy).
Why did I get A=100 instead of 95?

Could someone possibly tell me what privacy protecting technologies does hyperledger apply?
hiepnm
2016-11-07 08:52
I want to ask a question about hyperledger theory that relevant to their use cases.
I'm using hyperledger fabric to solve my _music streaming security_ problem.
The _asset_ in my project are _keys_ that _encrypt/decrypt the mp3 files_. And those keys are stored in my ledger. Users who upload the mp3 files to my media server, keep the keys about those mp3 files. So, _Every user keep a their own ledger_.
Should I create a new validating peer once a new user join my blockchain network?
rishavkmr09
2016-11-07 10:19
After a user invokes a chain code and the completion of a transaction in which format does the data on blockchain gets stored and where ??? @garisingh Can you please provide some links regarding this issue?
hiepnm
2016-11-07 10:26
@rishavkmr09 I have the same question. You can look up at: /var/hyperledger/db/ directory on your validating peers. (production folder is used for production mode). And I'm investigating how to retrieve it using dbutility: https://github.com/hyperledger/fabric/tree/master/tools/dbutility
garisingh
2016-11-07 10:29
@rishavkmr09 - check out http://hyperledger-fabric.readthedocs.io/en/latest/protocol-spec/#32-ledger - it gives some background about the `ledger` and the `world state`. From an implementation perspective, in v0.6 of the Fabric both of these are stored in RocksDB.
At a high level, the ledger contains blocks with each block containing a set of transactions and each transaction essentially being the command you invoked (e.g. chaincodeID, function, parameters). The world state contains the current value for any key which has been set/modified by chaincode
hiepnm
2016-11-07 10:31
@garisingh thank you! How do I get a world state value that relevant to a transaction in history?
hiepnm
2016-11-07 10:33
Example: I have A=200, invoke(A-1), invoke (A-1), invoke (A-1). So A= 197. And I have 4 transactions in my block. I want to get the world state value that relevant to the second transaction (I expect A=199).
garisingh
2016-11-07 10:37
@hiepnm - unfortunately in the current release (v0.6), there is not really a built in historical query to retrieve point in time value of any given key
hiepnm
2016-11-07 10:40
@garisingh thank you. I'm reading this topic http://hyperledger-fabric.readthedocs.io/en/latest/protocol-spec/#32211-bucket-tree
And I want to retrieve it inside the chaincode logic. Is it OK?
hiepnm
2016-11-07 10:43
I'm reading that topic, but I don't understand it.
garisingh
2016-11-07 10:45
@hiepnm - the only "data access" APIs within chaincode are PutState and GetState (well there are a few higher level tables APIs as well)
garisingh
2016-11-07 10:46
most of the stuff in the protocol spec would not be applicable from a chaincode development perspective

@hiepnm To identify a value on the ledger at "n"th transaction, you could use a chaincode that counts the transactions, and uses the counter as part of the key for the data to index into the correct item in the ledger. We modified example02 to do something like this. The chaincode keeps track of transactions, and each transaction adds a record to the ledger. Subtractions are not done, so admittedly it is not a completely realistic chaincode design for many application usecases. Moreover, if you are looking to keep track of batches on the ledger (which could contain multiple transactions), then it does not do that, because as garisingh mentioned the peer network does not provide that service. For our "add-records" chaincode, refer to: https://github.com/scottz64/obcsdk/blob/master/ledgerstresstest/example02_addRecordsToLedger/chaincode_example02_addrecs.go

you need to pull down the base image from docker hub and then re-tag it as latest

jzhang
2016-11-07 19:54
@bain don’t believe your question above has been answered, but this means that the member service and your SDK’s local store (keyvalstore) are out of sync
jzhang
2016-11-07 19:55
either you changed to use a different local store and are using the same member service, or re-init’ed the member service but using the same local store from before.
jzhang
2016-11-07 19:56
easiest way to fix it is, if you can, re-init the member service and delete the local kvs

Hi all - does anybody know how i can getRows by specific keys? According to the documentation, I can get the rows by key A,C:
```
// GetRows returns multiple rows based on a partial key. For example, given table
// | A | B | C | D |
// where A, C and D are keys, GetRows can be called with [A, C] to return
// all rows that have A, C and any value for D as their key. GetRows could
// also be called with A only to return all rows that have A and any value
// for C and D as their key.
```
This is working for us, but now we trying to get the rows by keys [C,D] (A any value). How can i implement that in go?
sstone1
2016-11-08 10:09
@eugenluft you cannot do that with chaincode tables; as the comment says you can query using A, A + C, or A + C + D
sstone1
2016-11-08 10:11
this is because of how the tables are mapped onto the underlying key/value storage (accessible via GetState/PutState)
eugenluft
2016-11-08 10:12
@sstone1 oh no :flushed:
eugenluft
2016-11-08 10:16
@sstone1 any idea how do solve this issue?
humblealex
2016-11-08 10:34
@astepanov I think this example should be ran by asset_management/app/app.go, you can refer to the README.md in that folder. The metadata should be filled manually by app. If you simply deployed that chaincode, nothing would be filled into metadata by default. That is probably why it returns empty.

Why? :disappointed:
garisingh
2016-11-08 11:09
@hiepnm - the fabric master branch is where we are doing all of the work for the V1 release of fabric. We've made some code organization changes in V1, including moving all of the SDKs (Node.js, Java, Python) into their own repositories. We are also doing a major restructuring / new implementation of the features that were in membersrvc and created a separate repo (fabric-cop) for that. You'll also notice that we are re-implementing the crypto libraries as well in a more modular fashion.

@hiepnm yes: string "An" is the key for the n'th element added to the ledger. B is repurposed to simply be the counter N, the number of records added.
scottz
2016-11-08 14:42
@hiepnm and the invoke args would look something like: []string{"a" + strconv.FormatInt(cntr, 10), DATA, "counter"}
garisingh
2016-11-08 14:52
@gokulamurthy - if you recently pulled down and/or updated your fabric master branch, membersrvc is no longer there
garisingh
2016-11-08 14:54
are you planning to contribute to the fabric or simply looking to develop chaincode and applications? If the latter, then I still recommend you use the prebuilt Docker images. If the former, v1 no longer leverages membersrvc. The new architecture is more modular and the mebersrvc capabilities are being redesigned / re-architected in the the fabric-cop repo

to use pbft you should either set it up in `core.yaml` or via environment variables

Here is my docker-compose.yaml file:

rain8010
2016-11-10 09:00
Yes. I set the core.yaml. But if I don't use the environment CORE_PEER_VALIDATOR_CONSENSUS_PLUGIN. The pbft doesn't work.
zemtsov
2016-11-10 09:01
have you rebuilt your image after editing core.yaml?
rain8010
2016-11-10 09:01
No. I have not.
rain8010
2016-11-10 09:03
Do I need to rebuild the image after editing core.yaml?
zemtsov
2016-11-10 09:04
I’m not fully sure but I believe so. And why do you want to use core.yaml to set you image up? Isn’t it easier to set all you need with variables?
zemtsov
2016-11-10 09:05
try to `make peer` again. If it helps, then yes, you need to rebuild it after editing :slightly_smiling_face:
rain8010
2016-11-10 09:07
I thought the yaml file is a configuration file. Generally, the configuration should be dynamically set. But I will try to built the image again. Thank you.
zemtsov
2016-11-10 09:08
Yes, this is a configuration file but I’m not sure if it is used at the start

@zemtsov You might find it easier to use docker-compose (which is just a config file like you suggested - No rebuilding) and docker images if you're only developing for chaincode.
zemtsov
2016-11-10 09:29
@pd93 agree
rain8010
2016-11-10 09:39
@pd93 , I make peer again. But It seems the pbft still doesn't work, if I only set the validator.consensus to pbft in the core.yaml file without setting the environment.
pd93
2016-11-10 09:58

garisingh
2016-11-10 12:30
I always ask this, but why? we have published Docker images
garisingh
2016-11-10 12:31
basically, building native outside Vagrant was not supported in v0.6. @ghaskins is doing the work to make this possible for the v1 architecture
garisingh
2016-11-10 12:31
I don't run OSX Sierra but I can build native on OSX El Capitan
garisingh
2016-11-10 12:32
someone else asked this question - I forgot to ask which version of OSX they were using. But there seems to be something incompatible with the way one of the scripts in the build works
garisingh
2016-11-10 12:33
so unless you are modifying the source code of the peer or membersrvc, I'd highly suggest using the Docker images
somashekar
2016-11-10 12:40
@garisingh , I completely understand but we are working on building something 3party like package for a specific domain. I will check and see if I can work on the docker image.
garisingh
2016-11-10 12:49
ah - I see - makes sense to try to build then. but perhaps it would be easier to just build your own Docker image if the make targets are not working
garisingh
2016-11-10 12:49
there's a lot of env variables, scripts, etc in the make approach

Hi, I have a question about querying tables. I have a table with 3 keys. Example: Surname, Name, RegistryNumber. If I perform a Lookup with all 3 keys, I'll receive one row. I perform a lookup with keys: Surname, Name, I receive 1 or more rows. But when I do a lookup by the third key only. I don't receive any information. I perform the lookup as such: nill,nill, RegistryNumber. How do I perform a lookup with only the third Key and the other blank values?

I have pulled the docker images for peer and membership service from docker hub. I presume these images are v 0.6. I am trying to figure out location of 0.6 git repository that I need to clone for chain code development. Documentation at https://hyperledger-fabric.readthedocs.io/en/latest/dev-setup/devenv/ suggests "git clone && scp -p -P 29418 :hooks/commit-msg fabric/.git/hooks/ " I do not have LFID and I am not sure if this references the v 0.6 code. Appreciate any help.

@jov Acctually you cannot. The current Getrows in table only support pulling out data by using the keys in the exact order you defined when creating the table. This means that you can only use the combination of key1, key1key2, key1key2key3, ... etc. The principle of the table is another way of putting state using keys. What GetRows really does is that Getting state from keys that contains key1, key1key2...

@rain8010 No problem. I get the feeling we're in different timezones :stuck_out_tongue:
You shouldn't be building your peer if you're trying to use docker-compose. Either you edit the core.yaml, build the peer and then run it from inside vagrant with "peer node start" OR you can run the docker-compose file, which will run the pre-built docker image with the settings you add to the compose file (At least that is my understanding).

Hi all. I'm setting up fabric on 2 different servers, one for validating peer and another for CA.
From the instructions given in https://hyperledger-fabric.readthedocs.io/en/latest/Setup/ca-setup, I see that to set up CA and VP on the same docker, we have to use docker-compose.yml as shown below.
membersrvc:
image: hyperledger/fabric-membersrvc
command: membersrvc
vp0:
image: hyperledger/fabric-peer
environment:
- CORE_PEER_ADDRESSAUTODETECT=true
- CORE_VM_ENDPOINT=http://172.17.0.1:2375
- CORE_LOGGING_LEVEL=DEBUG
- CORE_PEER_ID=vp0
- CORE_SECURITY_ENROLLID=test_vp0
- CORE_SECURITY_ENROLLSECRET=MwYpmSRjupbT
links:
- membersrvc
command: sh -c "sleep 5; peer node start"
If I'm having CA and VP on different servers then how will the individual docker-compose.yml files look like?

@tuand Thanks. But to do that I should have the fabric source instead of the fabric-peer docker image right? Because I'm using the docker image currently.

You can override the membersrvc config values in the docker-compose file, same as CORE_LOGGING_LEVEL for example

On my phone so i can't look at core.yaml right now. But find out the keys for membersrvc address:port and override in docker-compose with CORE_whatever

HI, I've updated fabric from git. Now i can not start peer node. I get [committer] NewDeliverService -> ERRO 05a Cannot dial to 127.0.0.1:5005. How can i fix this ?

I think you need to get the real container IP address instead of 127.0.0.1
aybek
2016-11-14 06:20
@jared that didn't change anything
jared
2016-11-14 06:22
what's your docker-compose.yml?
warm3snow
2016-11-14 06:27
@aybek I think it's Port problem. Your ./peer version may be different with the peer images.

Why aren't the changes to the state variables caused by any chaincode method being logged as a part of transaction? What I see in the payload of any transaction is just the base64 encoding of the description which contains (1) Chaincode ID (2) the method invoked, and (3) the arguments passed to it.

for chaincode development, I want to customize error return in invoke call, but it always return “ok” and transaction id even I write like “ return nil, errors.New("Received unknown function invocation”) " , for query method ok, but could we get customize error return from invoke?? thanks

@aybek vagrant and docker two different things vagrant work with Virtual machine and docker work with container you can not use both because they are two different components

Hi , Does any one know the CORE_VM_ENDPOINT of IBM container on Bluemix? I can deploy the ibmblockchain image https://hub.docker.com/u/ibmblockchain/ on Bluemix container. The fabric-peer container runs fine. But when I deploy chaincode_example2, I fail in setting correct VM_ENDPOINT. I have tried http://172.32.0.1:2375 ,https://virtualmachines.ng.bluemix.net , https://containers-api.ng.bluemix.net, https://mccp.ng.bluemix.net. Neither one of them work. The environment is just for testing purpose. Just want to see if anybody have ever try to do this and have the answer.

Hello, I wonder if there is a way to get member transaction history by using fabric-sdk-java or chaincode. Second, I also want to get a member’s assets by using TableExample (Table: AssetsOwnership, Columns: Asset{key}, Owner) in the examples package, but key column is unique and I can't get multiple rows as a result of stub.getRow method. For instance, insert rows {{Asset1, Owner1}, {Asset2, Owner1}, {Asset3, Owner2}} and want to getRows that has Owner1 at Owner column.

Hi, I'm a beginner on Hyperledger trying to register new user to membership services. I tried to run the example node.js in starter container to add user "JohnDoe" predefined in the code and found no problem when running. As I noticed, after running, member.JohnDoe file was created in /tmp/keyValstore directory but I can't use the enrollment secret located in the file to enroll that user via RESTAPI. "Error": "rpc error: code = 2 desc = Identity or token does not match.", it said. The status of this user is also not logged in. Could someone please advice on this? Thanks
P.S. As I noticed, there is ecert_JohnDoe file generated in /tmp folder in membersrvc node but no enrollment.key file generated in /var/hyperledger/production/crypto/client/JohnDoe/ks/raw folder in peer node.
ankitkamra
2016-11-15 04:22
@newdev2524 By default, this is one time use enrollment id and secret. so you can't reuse it to login
ankitkamra
2016-11-15 04:23
try two things remove directory /var/hyperledger/production on memebersrvc peer and remove /tmp/keyValstore file
ankitkamra
2016-11-15 04:23
then you will be able to use that enrollment id and secret again
newdev2524
2016-11-15 04:38
@ankitkamra Many thanks for your advice. another question is why the status of that user was not logged in. Can we make the status persistent for running another chaincode? (as I tried to understand the code in node.js file, we haven't logged out that user after running example chaincodes). I have no idea how to register the user permanently online instead of putting into the membersrvc.yaml file.
ankitkamra
2016-11-15 04:47
@newdev2524 according to my current knowledge, there is no way to make it persistent. You can register user online using HFC. just install using command npm install hfc
ankitkamra
2016-11-15 04:49
because of according to hyperledger architecture its gives one time password using which when you login CA server issues crypto token. In which a part exist on server side in /var/hyperledger/production/.membersrvc and another part on client side /tmp/keyValstore so you need to clear on both side if you want to reuse the token
newdev2524
2016-11-15 05:00
@ankitkamra the sample node.js file uses HFC. just wonder why the sample can run multiple chaincodes until the end of node.js file after running registerAndEnroll Function in there. When was the token (or status) not valid/disappear). Another thing, why we can make the status always "logged in" after enrollment for the users located in membersrvc.yaml file). Can we do like that for user registered online?
ankitkamra
2016-11-15 05:05
@newdev2524 which node.js sample, you are running ?
ankitkamra
2016-11-15 05:05
and when both side token exists it gives message on peer "USER Already logged in"
newdev2524
2016-11-15 05:10
@ankitkamra in the "starter" container (/opt/gopath/src/github.com/hyperledger/fabric/examples/sdk/node) but it seems we can get it from membersrvc or peer node as well.
Is it possible that when we register the user online, it gives us the token which valid only for one chaincode name ? that makes it different from the user registered permanently in membersrvc.yaml file?
ankitkamra
2016-11-15 05:13
@newdev2524 As we know there is a common CA server so by default when a user get token it will be able to invoke any chaincode by chaincode id.
ankitkamra
2016-11-15 05:14
there must be an access control mechanism to do this currently i am doing POC for that so i am sory
ankitkamra
2016-11-15 05:14
sorry
ankitkamra
2016-11-15 05:14
i cant help you in that at this moment
newdev2524
2016-11-15 05:16
@ankitkamra If so, how can we make the user always "logged in" when registers and enrolls online (use HFC) like when we do for offline (membersrvc.yaml file) and enroll? Thank you very much for your kind response anyway : ) . Anybody else can help answer on this ?
ankitkamra
2016-11-15 05:21
@newdev2524 it supports by default, just try one thing create a new user and get token by login after then retry to login there will be message on ca and peer "User is already logged in" and hence there is token on both side you will be able to invoke chaincode. just do implementation in node.js application whatever message you want to show to end user.
ankitkamra
2016-11-15 05:23
As well as when a user is already logged in and you try to login again using rest you will get json response with error message "User is already logged in" so, depending on this response you can do your own implementation in frontend application .
newdev2524
2016-11-15 05:38
@ankitkamra i tried to register and enroll via hfc and enrolled again using REST. REST got "Identity or token doe not match" instead of " USER already logged in " That's the situation I asked you. Is it possible that we can use only one channel (REST or HFC) for one specific user?
ankitkamra
2016-11-15 05:41
checkout this link https://github.com/hyperledger/fabric-sdk-java#basic-troubleshooting
ankitkamra
2016-11-15 05:43
according to this in relogin situation it will give messages like "Identity or token doe not match" or "User is already logged in" to make it consistent you need to check fabric code
newdev2524
2016-11-15 05:47
@ankitkamra Another question ... when we did enroll via hfc, why we did't get enrollment.key file in /var/hyperledger/production/crypto/client/JohnDoe/ks/raw like other users in membersrvc.yaml
ankitkamra
2016-11-15 05:50
Because that user are registered with membersrvc service you have not enrolled in yet for understanding, its like user exist in database but you have not logged in yet
ankitkamra
2016-11-15 05:50
whenever you will login you will get similar file
newdev2524
2016-11-15 05:57
@ankitkamra: I already enrolled via registerandEnroll function (HFC) before running the chaincode (invoke, query) with success but didn't get enrollment.key file
ankitkamra
2016-11-15 06:00
@newdev2524 okay i need to check it, i will get back to you if i got the answer

2016-11-15 06:00

@abhishekseth What error are you facing ??
newdev2524
2016-11-15 06:27
@ankitkamra just for your information. running the registerAndEnroll in node .js file doesn't return the enrollment.key and related files in peer node. The token doesn't match when enrolled again via REST. The user wasn't already logged in as well
function enroll() {
console.log("enrolling user admin ...");
// Enroll "admin" which is preregistered in the membersrvc.yaml
chain.enroll("admin", "Xurw3yU9zI0l", function(err, admin) {
if (err) {
console.log("ERROR: failed to register admin: %s",err);
process.exit(1);
}
// Set this user as the chain's registrar which is authorized to register other users.
chain.setRegistrar(admin);
var userName = "JohnDoe";
// registrationRequest
var registrationRequest = {
enrollmentID: userName,
affiliation: "bank_a"
};
chain.registerAndEnroll(registrationRequest, function(error, user) {
if (error) throw Error(" Failed to register and enroll " + userName + ": " + error);
console.log("Enrolled %s successfully\n", userName);
deploy(user);
});
});

Checkout start and end date of certificate and try by changing your system date that must be in between start and end date of certificate
ankitkamra
2016-11-15 06:57
another option is to create a new certificate with same cipher and try with that certificate

You may get certificate dates and cipher info using openssl command if you are working in unix environment

I'm using fabric v0.6.1 via docker in production mode, I can deploy chaincode by peer command successfully. but failed when I do deploy operation with HFC. The chaincode container can not be started, I found the log of docker container as below.
src/build-chaincode/hello.go:6:2: cannot find package "http://github.com/hyperledger/fabric/core/chaincode/shim" in any of:
/opt/go/src/github.com/hyperledger/fabric/core/chaincode/shim (from $GOROOT)
/opt/gopath/src/github.com/hyperledger/fabric/core/chaincode/shim (from $GOPATH)
It seams chaincode compile error because the docker container has no fabric environment.
Related docker containers' names are "jovial_chandrasekhar" and "serene_hypatia".
Related docker image name is "b1d7277763ad".
Only Production mode, DEV mode is no problem.
Anyone can help? Thanks.

hi @bain. Probably you need to vendor you code

hi @zemtsov . My code has been involved into the peer container by volumes setting. I can do the same deployment operation with peer command and RESTful API in the same environment.
bain
2016-11-15 08:56
As we known, the RESTful API maybe be removed in v1.0. I'm transferring my demo app from REST API to HFC.

I can compile the chaincode in peer container now. But the HFC will run another container to build chaincode, but it seams that the build container has no fabric to compile chaincode.

Hi, should function argument from invoke contains “invoke” or should it contains the requested chaincode business method (ex: GetUser)?

@yacovm #SimDa I using IBM Bluemix Blockchain Hyperleger Technology to record the transcription or transactions
Where I still looking for a protocol or standard like ripple to move physical currency or digital currency..

#SimDa solution is P2P payment for Ecommerce API under IBM bluemix Hyperleger technologies with a working prototype and had done live transactions..

what's wrong with bluemix?
qjawe
2016-11-15 17:49
@yacovm because SimDa doesn't have any website nor any social media accounts yet!!
So the best fix will be #SimDa
qjawe
2016-11-15 17:51
There nothing wrong with IBM bluemix, they are amazing Hyperleger codes..
Just in case enterprises customers need another option or widen my Hyperleger knowledge

Hi,
I'm following the hyperledger docs (http://hyperledger-fabric.readthedocs.io/en/latest/Setup/Chaincode-setup/#running-the-validating-peer)
At the this point I stuck:
cd $GOPATH/src/github.com/hyperledger/fabric/peer
peer network login <username>
<username> is expected to be in membersrvc.yaml but it's missing: https://github.com/hyperledger/fabric/blob/master/membersrvc/membersrvc.yaml
Further:
make membersrvc
gives this error:
make: *** No rule to make target 'membersrvc'. Stop.
Thanks for help!

Hello...mmm... in "Java Chaincode Setup" part of the docs explains that I need to use "vagrant", which I didn't install as I want to go directly to the Docker / docker-compose approach. Is there a way to get into Java chaincode development without using vagrant? Also, second question, I see that the example references $GOHOME when talking about gradle. Do I need to install and use GO language to deal with Java chaincode programming? Thanks for any directions.

Hi all! Noob question: I want to evaluate building apps on hyperledger. I've started with https://github.com/IBM-Blockchain/learn-chaincode and compiled the example chaincode. However I aborted because I felt like I have to know more about the different blockchain implementations withing hyperledger first. How does fabric compare to sawtooth? What other blockchain implementations are there, and what use cases do the address specificly?
- My preferred (but not only) use case is IoT related, e.g. have a device react to the state of a smart contract
- I like the idea of ethereum's solidity as a special purpose language for smart contracts

@arvin the simplest way for now to install COP is as follows
keithsmith
2016-11-17 13:49
# mv $GOPATH/bin/cli $GOPATH/bin/cop
keithsmith
2016-11-17 13:51
We will be changing the cli directory name to cop so the rename isn't needed, unless someone knows how to cause go get to name the executable something other than final directory name
keithsmith
2016-11-17 13:51
we can provide a docker compose in future

I have some questions,
1. Is it possible to getState() concurrently? is there any lock? Can I actually getState in parallel?
2. For every single chaincode, we will get its chainhash once deployment. However, in the case that we need to modify the chaincode, we will have a different hash. The question is that, how can we retain those states from the old chaincode to the new one. Is it possible to do?
ibmdannywong
2016-11-21 01:50
@stylix
1) What do you mean by getState() concurrently? Concurrently getState from Node SDK? from same smart contract within same node?
2) No at current v0.6 (unless you are running in DEV mode), which means it requires data migration your old states to new chaincode (with new hash). Only in v1.0 has the "upgrade chaincode feature"
stylix
2016-11-21 01:58
Thanks @ibmdannywong
1) I mean the chaincode in Go, when one line of code is doing getState(), will it get lock if I make another thread to getState() on the same key?
2) So, we need to wait for v1.0 then.
ibmdannywong
2016-11-21 02:01
@stylix Re: #1, I don't think so. But where is there another thread?? Do you mean another executing contract method (that attempts to getState with same key) when there is another one executing in parallel on same node?
ibmdannywong
2016-11-21 02:01
Why is there* not where is there...
stylix
2016-11-21 02:05
@ibmdannywong We implemented a very heavy method during query, I mean a lot getState() there. So, we are thinking about to make another thread to getState() in parallel. If no lock during getState(), it's worth to try this in parallel, if possible.

@stylix Although technically feasible, I don't recommend to do so... Have you considered applying Event Sourcing and CQRS pattern over your application
ibmdannywong
2016-11-21 02:46
The blockchain ledger is a typical event store (append-only write)
ibmdannywong
2016-11-21 02:47
it is specialized as a write model, I understand there is a "query" method in each contract. However, we should use different read view for different use case.
ibmdannywong
2016-11-21 02:47
Otherwise, your read performance wont be too good
ibmdannywong
2016-11-21 02:49
umm... I should ask, what is the purpose of that heavy query method?
ibmdannywong
2016-11-21 02:49
for application side use in one organization / by all participants in business network?
stylix
2016-11-21 02:54
Thanks @ibmdannywong I'm not so sure much about Event Sourcing, CQRS.
Anyway, we are now trying to do a kind of information retrieval through a blockchain.
That's why, it's heavy query
stylix
2016-11-21 02:55
of course, we can just use elasticsearch or what ever, but we just what to try this out to see if HL can handle this POC
ibmdannywong
2016-11-21 02:56
ic, I think HL can handle the "many getState" calls well
stylix
2016-11-21 02:56
but seemed, slooooow :disappointed:
ibmdannywong
2016-11-21 02:56
lol
stylix
2016-11-21 02:56
we also try getRange, then.. slower
ibmdannywong
2016-11-21 02:57
well, it's not a RDBMS... but a Key-value store...
ibmdannywong
2016-11-21 02:57
so getRange is just scanning i think*
stylix
2016-11-21 02:57
btw, I found this issue during our query
https://jira.hyperledger.org/browse/FAB-1163
stylix
2016-11-21 02:58
when a query over 30sec, chaincode just crash out
stylix
2016-11-21 02:58

ibmdannywong
2016-11-21 02:58
well, not much idea...
stylix
2016-11-21 02:59
that's alright, we will try parallel getState, to see what will happen
bain
2016-11-21 02:59
@ibmdannywong @stylix I suggest to use timestamp check to instead of key lock.

stylix
2016-11-21 03:00
@bain not sure about this, actually
bain
2016-11-21 03:01
we can store json data in rocksdb, just like {"val":"xxxx", "rev": "1234567890"}
bain
2016-11-21 03:02
before we update value, we need to check if the rev is right.
bain
2016-11-21 03:02
after update the value, we need update a value for rev.
bain
2016-11-21 03:02
just like cloudantDB
stylix
2016-11-21 03:04
hmmmm

Question: Speed of Invoke: We have tested the speed of "Invoke". It takes 200ms to complete. It seems slow. Is it normal? (The "Invoke" put a simple state; It involves 2 peers on same machine.) Thanks you.
alanlee
2016-11-21 04:36
(We use REST to invoke. Actually, we want to see how many requests can be handled per seconds for the invoke.)
bain
2016-11-21 04:39
We had tested such case. Normal speed can be 80 tps in notebook.
alanlee
2016-11-21 04:43
Thanks @bain. How many peer nodes (over network)? With TLS configured? I assume you are putting variable in invoke too. I assume you are using notebook around i7 cpu. Thank you.
bain
2016-11-21 05:44
@alanlee I just run one peer with production mode in VM(1 cpu, 2G mem). And tested with Jmeter, the result is about 80 tps.

Hi ,
We are running fabric in prod mode which requires the git repo path at the time of chaincode deployment.
Currently we are unable to deploy the code from a private git repo. Is there a way around this? Could anybody please help on this issue?
Thanks
bain
2016-11-21 07:06
@matpasha you can use local path instead of git repo path.
matpasha
2016-11-21 07:08
@bain Is it possible to do that in production mode now? I thought we had to give the git repo path in prod mode.
bain
2016-11-21 07:10
@matpasha it's possible, if you can upload your chaincode source to the peer server before.
bain
2016-11-21 07:11
@matpasha I'm using docker env, I attach some volumes to contain the chaincode, and then call deploy with local path, it's OK.
matpasha

@bain I am deploying using swagger and trying to give my local path "/Users/matpasha/Jarvis1/Chaincode" for deployment but it fails with the following error "Error when deploying chaincode: Path to chaincode does not exist: /Users/matpasha/Jarvis1/Chaincode" what am I doing wrong? Thanks
bain
2016-11-21 07:29
@matpasha you need use guest local path instead of your host path
bain
2016-11-21 07:32
@matpasha for example:
volumes:
- /Users/XXX/xxx/chaincodes:/opt/gopath/src/chaincodes
your chaincode is /Users/XXX/xxx/chaincodes/hello/hello.go
you need use "chaincodes/hello" as chaincode path.

@satyam_agl - thanks for the update. I'll also assume that you are trying to compile `chaincode_example02` locally on your Windows host? If that's the case, it is a little tricky (but not too bad). Basically, Windows for Docker actually runs Docker in a VM and *almost* makes this seamless from a user experience. The trick is that when you expose ports via Docker for Windows, they are actually exposed via the bridge address for the underlying VM. If you bring up another *Docker QuickStart Terminal*, you should see a line that starts with `Docker is configured to use the default machine with IP ....`. You want to grab that IP address and use it instead of *0.0.0.0* or *172.17.0.3*

Hello! I'm running fabric through CLI with `docker run`. I created instance of class where I run one peer, and sending and getting messages. The question is: why when I'm getting messages from root peer I got every message I invoke through all peers, but when I'm getting messages from not root peer, I am getting only those messages, that I invoke to this peer. Info on blockchain should be kept on all peers, isn't it?

@stylix it doesn't take effect even if the syntax is correct

btw, that Go lines are interesting, actually I cannot find where is the document on naming ENV correctly.

I think you should specify CORE_LEDGER_STATE_DATASTRUCTURE_CONFIGS=xxx
xixuejia
2016-11-22 02:41
yeah, your syntax is theoretically correct, but it doesn't take effect
xixuejia
2016-11-22 02:42
because it is extracted in a string map, not viper.GetInt("***")
stylix
2016-11-22 02:46
do you have an idea what should xxx look like if I need to set numBuckets to the configs?

I would recommend to change that value in core.yaml

yes, with yaml way, it works fine.
btw, my system current wrap HL in it and mostly override the HL through ENV
xixuejia
2016-11-22 02:50
are you using docker? if so, you could easily mount core.yaml in containers
stylix
2016-11-22 02:52
yes, we use docker, and we also use a docker swarm, then to be able to scale the node dynamically we prefer to override the parameter with ENV
stylix
2016-11-22 02:54
if we mount core.yaml, this static one does not scale fine, and we need to override this mounted core.yaml anyway, so a bit redundant.
stylix
2016-11-22 02:54
that's why I'm looking a correct way for ENV this
stylix
2016-11-22 02:55
but anyway, if no better choice, I will need to mount the modified core.yaml then.

Now when i try the peer chaincode deploy -n mycc -c '{"Args": ["init", "a","100", "b", "200"]}' in third terminal window ... i am getting the error - Error: Error getting chaincode code chaincode: Error getting chaincode package bytes: Cannot collect files from empty chaincode path. Help please as i have tried -p 0.0.0.0:7051 flag but that gives me a diff error ...

Hi,
I am trying to filter one a table by it's 3th column, this is my code
``` var columns []shim.Column
col3 := shim.Column{Value:&shim.Column_Uint64{Uint64:authorizerID}} //authorizerID is the parameter I want to filter on
rowChannel, err := stub.GetRows("RequestTable", columns)
```
My problem is now that this line of code does not filter on the 3th column, but on the first.
I also have tried this:
``` col1 := shim.Column{Value:nil}
col2 := shim.Column{Value:nil}
col3 := shim.Column{Value:&shim.Column_Uint64{Uint64:authorizerID}}
columns = append(columns, col1)
columns = append(columns, col2)
columns = append(columns, col3)
```
But then I got nothing back from `stub.GetRows("RequestTable", columns)`
Is there a way to skip the first and the second column, and filter on the 3th?
ps I am using Fabric 0.6

@xixuejia With my way, if we deployed several nodes on the network, then we need to read all those chainheight and currentBlockHash from all the nodes then compare. It may work, but it's hard to guarantee that the consensus process is done on all nodes (e.g. stop/idle/no more processing block).
So, if a lot of transaction are waiting in the queue too much, that will crash the node very soon. (take time to process the invoke longer than timeout)
However, I'm thinking it might be better/more appropriate to have access to this consensus state through the API/SDK way, so then we can easily throttling the transaction invocation speed.
But still don't know how/is it available here?

@vibhu -p is the path of the chaincode try providing the path to chaincode_example02
If you are trying from vagrant setup it would probably be "http://github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02"

I have a question about the way to use Git within this project (pertaining to submitting code for review)
garisingh
2016-11-22 20:02
sure
pschnap
2016-11-22 20:05
I checked out the project code a while go, made some additions, committed them then submitted for review. They were turned down, so I made changes the reviewers requested/suggested and amended my commit (though I've not yet resubmitted for review). Now I want to update the master branch (one revision behind my commit) and was wondering what the preferred way to do this was.
pschnap
2016-11-22 20:06
I was thinking of making a branch for my commits then resetting the head back a revision, updating the master, leaving my branch. I was unsure whether I should do a merge into my branch of the master before submitting again or whether this would mess things up
garisingh
2016-11-22 20:08
So I typically:
1) just keep my local master in sync with the origin (remote) master
2) create local branches for each of my changes
3) if my branch gets out of sync, I will sync my local master to the remote master and then rebase my local branch from local master
garisingh
2016-11-22 20:09
seems to be the pretty standard flow
pschnap
2016-11-22 20:09
I wondered if that would be an option but forgot what "rebasing" was called. I was also unsure if this would mess up the gerrit review stuff
garisingh
2016-11-22 20:10
nope
garisingh
2016-11-22 20:11
so for example if you push a change and then it shows as a merge conflict, just rebase your local branch, do git commit --amend and then git-review
garisingh
2016-11-22 20:11
it will actually show that you rebased in the comments for the latest patch revision
garisingh
2016-11-22 20:11
that part is actually nice
pschnap
2016-11-22 20:11
nifty
pschnap
2016-11-22 20:12
ok, I'll give it a try, thanks @garisingh !

Need suggestions to test/confirm PBFT on hyperledger. Any recommendation on how to setup the network to test for byzantine fault tolerance, think minimum 4 nodes needed, and for PBFT consensus no more than 1 ( < n/3) nodes should lie. How to make the one node in the blockchain n/w lie on the transactions? Anyone set it up, any guidelines/recommendations?

@warm3snow and @bfuentes thanks to both of you i will check asset management example. Can you please give reference of any java example ?

of course you can implement your own crypto currency and/or keep track of some type of currency within chaincode that you develop - but there's no currency entity intrinsic in the fabric

I have some funny problem about the consensus.
I send the invoke transactions to the different node, and wait for all nodes to reach the same consensus then I send another invoke (consensus checking by looking at the same number of block and same currentBlockHash on all nodes)
However, at some point, all the nodes reach the same block number, but with different blockhash. So any suggestion here?
sachinsurvase
2016-11-24 07:26
@stylix May be global_state is different

stylix
2016-11-24 07:27
btw if the global_state are different, should I submit more transaction?
stylix
2016-11-24 07:28
at least, total number of block are the same at all nodes
sachinsurvase
2016-11-24 07:30
If I understand correctly consensus algo won't allow adding blocks to chain
sachinsurvase
2016-11-24 07:30
if consensus is not met
sachinsurvase
2016-11-24 07:30
so all further transactions won't get added to chain
sachinsurvase
2016-11-24 07:30
so no point in submitting more

** If I understand correctly consensus algo won't allow adding blocks to chain if hash is not same

@stylix now I'm running noops. Did you mean that the number of transactions per block is fixed like 1-1 if we're not running the consensus? Thanks
stylix
2016-11-24 08:31
No, with noops you can also change the size of it, on this file
https://github.com/hyperledger/fabric/blob/v0.6/consensus/noops/config.yaml
stylix
2016-11-24 08:32
@newdev2524 or with ENV mode, CORE_NOOPS_BLOCK_SIZE=1000
newdev2524
2016-11-24 08:35
@stylix the default is 500, that's 1 transaction per block, right? So, 1000 is for 2 transaction per block. Thank you so much for your answer
stylix
2016-11-24 08:36
500 means 500 transactions per block
stylix
2016-11-24 08:37
it's depends on which one come first, either blocksize or blocktimeout
stylix
2016-11-24 08:37
the block will be created based on this 2 parameters
newdev2524
2016-11-24 08:39
@stylix Could you share the PARAMETER for timeout? Thank you : )
newdev2524
2016-11-24 08:44
@stylix I found out that the default timeout in yaml file is 1s. Does it almost assume that the transaction per block is 1-1?
stylix
2016-11-24 08:45
CORE_NOOPS_BLOCK_WAIT=2 is the timeout that you need for noops
stylix
2016-11-24 08:46
in case you can submit transaction very fast, faster than 1s, so it will not be 1-1
stylix
2016-11-24 08:46
but the number of transaction will be limited by 500
newdev2524
2016-11-24 08:46
@stylix crystal clear! thanks @stylix

@stylix you met an interesting issue about consensus. did you check whether you chaincode will produce indeterministic results?
stylix
2016-11-24 09:30
I'm not so sure how can I check if my chaincode will produce some bad, inconsistent result or not.
xixuejia
2016-11-24 09:31
you could keep calling `invoke` functions and see whether it could recover
xixuejia
2016-11-24 09:32
:grimacing:
stylix
2016-11-24 09:32
As it will not happen that early, it usually happen far after I submitted invoke a lot already.
stylix
2016-11-24 09:33
You mean, even if the hash is different, I may try to submit and see what will happen?

xixuejia

yeah, that's my guess..
xixuejia
2016-11-24 09:34
you need to trigger at least 2 checkpoints for state transfer completely
stylix
2016-11-24 09:34
I never see it merge after that, and still don't know is there anything corrupted before?
stylix
2016-11-24 09:35
Well, I can try this if it happen again :disappointed:
xixuejia
2016-11-24 09:36
what's the block number when inconsistency happens? and the current block height?
2016-11-24 09:37
Guys can you please come and meet me?
stylix
2016-11-24 09:39
It's random, but for example, no. 220 as my last event
stylix
2016-11-24 09:40
sometime, I just ignore the hash, and continue submit the transaction until 500+ blocks then it crash (possibly other related reason)
stylix
2016-11-24 09:42
Different hash happened sometime before when I use noops, but I never expected this will also happens with pbft, actually.
stylix
2016-11-24 09:43
One thing is, I send transaction via different node.
stylix
2016-11-24 09:45
and if I submit it too fast, this will surely happen.
xixuejia
2016-11-24 09:55
interesting, it's reasonable for noops with this situation(fast submitting requests). as for pbft, it's most probably caused by indeterministic chaincode..
stylix
2016-11-24 10:06
not sure what would be a caused to this reason from my chaincode, difficult to find the true reason then.

@jzhang Hello Jim, I followed your recent (two weeks ago) youtube video on setting up Node.js SDK and running end-to-end test against the latest fabric from master. In the meantime both SDK and fabric moved forward, and I am having a hard time finding the most recent combination of SDK and fabric tags that can work together. It would be very useful if you could publish the latest fabric tag that the SDK is compatible with, whenever it changes. Would you consider it? Thanks!

Trying to create a network setup of 2 or more peers using the docker pull of images http://hyperledger-fabric.readthedocs.io/en/latest/Setup/Network-setup/#setting-up-a-network.
I have found out the CORE_VM_ENDPOINT for the docker containers(using ip add) and set them correctly as(CORE_VM_ENDPOINT=http://172.17.0.2:2375, CORE_VM_ENDPOINT=http://172.17.0.3:2375 for the 2 peers).
The peers are started correctly, and are discoverable.
However, when i try to deploy a sample chaincode, i get errors in the peer:
vp0_1 | 11:07:11.279 [dockercontroller] deployImage -> ERRO 019 Error building images: cannot connect to Docker endpoint
vp1_1 | 11:07:11.241 [dockercontroller] deployImage -> ERRO 01f Error building images: cannot connect to Docker endpoint

2016-11-25 16:36
how many rows in the chaincode table. sorry
muralisr
2016-11-25 16:37
Only way is to count using GetRows. Alternately you can maintain a state var for that. Though you have to make sure its consistent with the number of rows in the Table, it maybe worth doing that for large tables
eugenluft
2016-11-25 16:39
@muralisr but my problem is, that i have a table with two keys A | B. Without enter A I can not call GetRows, right?
tzukru
2016-11-25 16:39
if there are two key columns (Key: true) and you want to get rows by second key, what would be the syntax?
eugenluft
2016-11-25 16:41
@tzukru you can not do that with chaincode tables
tzukru
2016-11-25 16:41

and pass :
keys = append(keys, _)
keys = append(keys, ownerKey)
rowChannel, err := stub.GetRows("AssetsOwnership", keys)
eugenluft
2016-11-25 16:43
but this is not working. As the documentation says you can query using A, A+C or A+C+D
tzukru
2016-11-25 16:44
i want to get all assets that the owner owns.
tzukru
2016-11-25 16:45
then i might be set first column owner and second asset, and query with A or A+B
eugenluft
2016-11-25 16:46
@tzukru this is exactly how we have solved the problem :wink:

Regarding Byzantine PBFT behavior.
Trying to setup hyperledger blockchain n/w with multiple peers and few byzantine nodes among them to check byzantine behavior.
If I have 2 byzantine nodes in 7 peers, the consensus should fail ideally.
However I can check from logs continuous messages:
vp6_1 | 13:40:18.542 [consensus/pbft] sendViewChange -> INFO 307 Replica 6 sending view-change, v:1, h:0, |C|:1, |P|:0, |Q|:0
vp6_1 | 13:40:18.544 [consensus/pbft] recvViewChange -> INFO 308 Replica 6 received view-change from replica 6, v:1, h:0, |C|:1, |P|:0, |Q|:0
vp6_1 | 13:40:18.545 [consensus/pbft] recvViewChange -> WARN 309 Replica 6 already has a view change message for view 1 from replica 6
Does this point to consensus still trying to be reached, which will not be possible because of 2 byzantine nodes among 7 nodes.
How can i stop the consensus trying to halt after some time. Can i use general.timeout.request? If yes then what is the command line environment variable for it, as I am starting the peers through docker-compose, so need CLI option.
Also, even after i add a peer and start 8 peers with 2 byzantine, i could see in the logs below details, and number of peers being considered is only 4.
14:43:14.552 [consensus/pbft] newPbftCore -> INFO 013 PBFT Max number of validating peers (N) = 4
14:43:14.552 [consensus/pbft] newPbftCore -> INFO 014 PBFT Max number of failing peers (f) = 1
14:43:14.552 [consensus/pbft] newPbftCore -> INFO 015 PBFT byzantine flag = true
14:43:14.552 [consensus/pbft] newPbftCore -> INFO 016 PBFT request timeout = 2s
14:43:14.552 [consensus/pbft] newPbftCore -> INFO 017 PBFT view change timeout = 2s
14:43:14.552 [consensus/pbft] newPbftCore -> INFO 018 PBFT Checkpoint period (K) = 10
14:43:14.552 [consensus/pbft] newPbftCore -> INFO 019 PBFT broadcast timeout = 1s
Even if i start 8 peers, it shows maximum number of validating peers as 4 only, why? Is there a limitation of 4 validating and 1 byzantine peer?

@meghana It seems you have set 192.168.0.2:3128 as your http_proxy. Ensure that the proxy is accepting connection. If proxy is not needed, unset the http_proxy, https_proxy environment variables.

yeah??

also better to set proxy for Docker daemon

Vagrant will bring up a VM for you ,when you run "vagrant up". Did you set the proxy in that VM?

no

2016-11-28 07:21
should I set the proxy in that VM ? But, it set the global proxy to over the wall to use shadowsocks

ankitkamra
2016-11-28 07:59
@gokulamurthy you need to use port forwarding
ankitkamra
2016-11-28 07:59
first of all do port forwarding from host to guest for this you need to modify Vagrantfile
ankitkamra
2016-11-28 08:00
after then from guest machine to docker use docker-compose to expose the ports

A company in Germany is testing Hyperledger on z. They are using the IBM signed and tested images from github with the installation procedure from https://hub.docker.com/r/ibmblockchain/fabric-peer/
They can start the peers with consensus noop, after 3 blocks the hashes diverge, but the fabric continues.
When they change consensus to pbft via parameter, the peers see each other and communicate. But "deploy" doesn't start a container. We don't know why.
Then they took the fabric-peer, changed consensus to pbft via core.yaml, and compiled in the container with "go build". They moved the binary to /opt/gopath/bin, committed the container, and tagged it with "ibmblockchain/fabric-peer:latest"
Then they did
docker run -d -it --name=vp0 -e CORE_VM_ENDPOINT=http://172.17.0.1:2375 -e CORE_LOGGING_LEVEL=DEBUG -e CORE_PEER_ID=vp0 -e CORE_PEER_ADDRESSAUTODETECT=true -e CORE_PEER_DISCOVERY_ROOTNODE=172.17.0.2:7051 -e CORE_PEER_VALIDATOR_CONSENSUS_PLUGIN=pbft ibmblockchain/fabric-peer peer node start
Again the hashes diverged after 3 blocks, but the system panicked and the peers died.
The problem is reproducable.
We can provide core.yaml, logs, blockchecks and commands.
Could you help?

I already have run a simple hello-world go build on the system without any issues, but when I ran the go build./*, the build hung. After ctrl-c out of the build command, any build attempts now fail with a fatal error unexpected signal during runtime execution. runtime.sigpanic(). I was wondering if anyone else had experienced anything similar. Thanks!

Any reason you have to "build" the SDK rather than just doing an `npm install hfc` and using it?

No. I can do that also.

```

npm install hfc

Hi guys, how can I clone from gerrit using ssh,
I've setup everything including LinuxFID and the ssh key on gerrit, but still got `Permission denied`
The http way with password works, but it can't be used to submit patch right?
fan.torchz
2016-11-29 16:27
@garisingh I met with similar problem before, just try to rebuild the toolchain about `node-gyp` and `node-pre-gyp`, try `rm -rf $HOME/.node-gyp` first
garisingh
2016-11-29 16:31
@fan.torchz - correct - you need to use git with ssh to submit
fan.torchz
2016-11-29 16:33
so does the gerrit need extra setup for permissions?

2016-11-29 16:34

The last query log show as {"result":{"type":"Buffer","data":[57,55]}}
I believe that data contain String "a=99"
Anyone know how to log out this String?

@heipi TPS in term of submitted transaction or completed transaction?
In term of completed transaction it depend on consensus algorithm and also many factors
like algorithm parameters, your node computing power, number of nodes, network etc...
You can google to find the claimed TPS for PBFT (default consensus alg. for fabric)
And consensus alg on fabric is plug and play, so actually you couldn't really said TPS for fabric,
as it will be different according to consensus algorithm module you use.

Answering to my question... So it a Buffer, and [57, 55] is the number it self.
Looking at ascii table it is '97'.. (run the sample several times so it not return [57,57]=99)
Uh, someone should refine those sample.
heipi
2016-11-30 02:39
@sk thanks
sk
2016-11-30 02:40
The sample chaincode already log the query result value as checked by `docker logs starter'
But we need those value on sample client app, right?
Adding this: `console.log("val of a=", results.result.toString());` as long as it return Buffer.
Now, why I got different number each time... does the deploy initialization value not working...
sk
2016-11-30 02:51
Okay, look like even though client app exec the deploy many times, the chaincode init() is only run once.
(unlike invoke(), obviously). Hmmm, is this deploy init behavior were documented somewhere?

2016-11-30 04:50
@sk As long as we deploy the same chaincode with same arguments (for init), it will not get re-deployed again; instead we get the same Chaincode ID of the one already deployed. If we change any of the deploy parameters, a new instance will get deployed. (What constitutes the chaincode ID is documented somewhere; couldn't find now).
sk
2016-11-30 06:09
@vigneswaran.r Got it, ty. I'm still learning a lot of things. Anyway then the func name itself: 'deploy' is
little bit misleading. Something like 'get' or 'getOrDeploy' maybe more understandable for my dummy brain.
just my 2c.

I have a question. Can IoT be used with Hyperledger? That is, is it possible for IoT devices to have TCert? In that case, does the IoT device need to have an ECert as well? By the way, the IoT device can not have a full block chain.
bfuentes
2016-11-30 13:08
@taishi ECert is the base, TCert can be request on demand. Yep, the IoT can only have the wallet and dialog with BC without being a "peer"
taishi
2016-11-30 14:17
@bfuentes I need to create that wallet with HFC sdk, right?

Hi all,
I'm trying to deploy a chaincode to the network in ibm.bluemix. The chaincode is from example asset_management.
Deployment fails on init, line :
adminCert, err := stub.GetCallerMetadata()
certificate is empty. Although i've registered admin user .
Could you please help , what is wrong ?

@aybek example asset_management should be run with the app which fills in the meta field of chaincode spec with adminCert, so the stub.GetCallerMetadata can get it on the chaincode side. If you just deployed the chaincode without running the app our manually filling the metadata filed of chaincode spec when deploying, you will get nothing with GetCallerMetadata function
humblealex
2016-12-01 01:10
@aybek check the app from asset_management/app/app.go & app_internal.go, you will know what I was talking about

as opposed to implementing order-matching outside of chaincode, and merely using the blockchain for *settlement*

@ceobco - assuming you are running on your own host (i.e. outside of Vagrant), you have to explicitly tell the Docker daemon to listen on TCP ( `-H ` )

one of my peers has become out of sync. I have 6 chaincode running. How would i go about recovering the peer?

the chancode is deployed via hfc with source code passed to it (source is not on filesystem of the peer)
cloud.strife
2016-12-02 17:17
the hfc client has been modified to create human readable chaincode names instead of the sha hash

Hi there

Hi Everyone, I have quick question regarding Chaincode to Chaincode invocation.
Suppose, I have two chaincode CC1 and CC2, and I am invoking CC1 and internally CC1 is invoking CC2.
In my case, transaction to CC2 is failing, but whole transaction (transaction to CC1) is successful. Ideally, if transaction to CC2 is failing, then transaction to CC1 should also fail because part of the transaction (transaction to CC2) is failing.
Exception thrown by CC2 is catching by System Chaincode (shim) but it is not informing CC1 about the failure of transaction to CC2.

kansi
2016-12-05 12:07
donjohnny you can check the git branch
kansi
2016-12-05 12:08
it should be v0.6
garisingh
2016-12-05 12:08
@donjohnny: If you are using the published Docker images you are using v0.6. If you built from master it's 1.0

@sumitks: not sure how you are deploying but looks like you are running in dev mode?
garisingh
2016-12-05 12:09
If so, you need to use the name parameter rather than path and the deploy name should match the name you started your chaincode with

Yes, I’m there too. I (personally) am still catching up what Corda has - so I don’t want to mislead. Maybe others can answer this then, but it’s probably also a good question for the discussions there (mind you, Corda’s code is open since Nov 30, yes still: I have made it a mission to learn all I can about it in the coming days.)

I am posting what is being presented at Hyperledger Hackathon on fabric-dev channel from Binh. He thanked the community for all their contributions and is looking for further input.. HE also highlighted 2 companies are already in production with Hyperledger-fabric on 0.6. He also covered lessons learned from the production and working with other companies that are baked into the version 1.0 design-- the details are posted on the slack channel fabric-dev

Jim shows everything native on his MAC. He is starting up COP (originally known as membership services). This is where he has the trust anchor for SDK involving the user. Users can then sign transactions and can be verified by the peers. Jim then starts up the network with 4 nodes and each will be using CouchDB under the cover
weeds

Binh presents the Schedule.
weeds
2016-12-05 15:28
of what he would like to propose for the roadmap
weeds
2016-12-05 15:30
What we have today- Endorsement model, dynamic multichain, SDK application, SDK, Pluggable identity, Pluggable data store, HSM support, access control, upgradeable chaincode, pluggable consensus
weeds
2016-12-05 15:30
For January- work with it for performance, security code hardening and what remaining items.
weeds
2016-12-05 15:30
In February- we want to propose exit incubator possibly if community approves
weeds
2016-12-05 15:31
We would continue to work in February and sometime we try to wrap everything up in release of version 1.0
weeds
2016-12-05 15:32
The Incubator designation is not about the product... the incubator graduation requirements is how is the team operating and checklist of other items. Brian is indicating that Fabric can do earlier than February and is independent . He felt we might be able to exit as incubation this month.
weeds
2016-12-05 15:33
Question: Is same way you could switch out couchdb and level db. Yes, you can contribute with database.. some people are already experimenting with MySQL and DB2.
weeds
2016-12-05 15:35
Back to the demo-> here is the cop that is providing trust anchor. The application can use the SDK using the specifications led by DTCC. Every transaction has 2 steps- one is to send the proposal,.. once the proposal comes back, you can inspect the endorsement results and compliant to your policy. The application decides whether to proceed with transaction and send to orderer.. and VSCC is the final validation. You can run w ith marbles end to end. Jim showed Marbles to couch db so the state is saved JSON documents... This allows you to do faster query.
weeds
2016-12-05 15:35
So now you can ask chaincode to do the state lookup or you can go directly to couchdb
weeds
2016-12-05 15:36
I sent a couple of transactions. He put three transactions in it already. Jim showed the native query on couch db-- showed json look up with nice Couch ui-- could do with perl or other clients.. He shows the result where there is no involvment of the peer nodes at all. This is helpful with data analytics,etc,.
greg_not_so
2016-12-05 15:37
checking in as i'm in the room as well
weeds
2016-12-05 15:37
Question: Where is the consensus algorithm executed? The way we define consensus is multiple steps. three steps--> at the endorser, the ordering, and the validation. This is different from 0.6 release where it was integrated. So now, we execute transaction and endorse,.. then we order,.. and validate
weeds
2016-12-05 15:38
There is a lot of ways to detect malicious peer. If replay attack- we can detect that. If it's honest, but malicious inside somehow- the transaction would ge through some endorsements if the endorsement is malicious somehow. Let's say transaction A and B... say A is malicious. It requires both of the signatures to endorse that transaction. The application can catch that quite quickly
weeds
2016-12-05 15:39
The consensus starts when transaction enters the system to where it ends.
weeds
2016-12-05 15:41
Brian Behlendorf asks what do you need from community? Binh responded on fabric such as- > Please contribute,.. please contribute on samples,. on please contribute on documentation,.. We do have tags in the code such as "help wanted"... Brian suggested maybe we need to produce a query for "help wanted"
weeds
2016-12-05 15:45
Binh indicated we had 100's of pocs from numerous companies and several people in production with the 0.6 version of the fabric. One important element is to take this level of code and to start really testing/ moving these pocs to version 1.0 and testing out the stability/quality finding all the relevant bugs
weeds
2016-12-05 15:46
Chris suggested- jumping in deep into code if you are not familiar probably isn't the best way to start if you aren't already there. He suggested get it up and working, improve the automation of getting it up and working, develop some samples to get it started,.. and help us improve documentation for the next guy. Additional tests, additional help , ease of use and user experience would be really helpful.
weeds
2016-12-05 15:47
Jim says we also want input on the SDK for stateless implementation for design. We have a task lined up in JIRA to do this.
weeds
2016-12-05 15:48
Brian Belendorf indicated for your code to be labeled Alpha, Beta, 1.0 release. This characterizes performance, security review,etc,.. is that aligned when you cut the release? We need to meet those.

In main dashboard - the market place is broken into assets and holdings of those assets.
weeds
2016-12-05 16:04
As a market- I'm going to create an asset-- on screen create asset- he filled out name, description, and asset type (a new one is being created)
weeds
2016-12-05 16:04
Why asset and asset types? You may want to categorize drugs- FDA approves all drugs and control drug approval, but then individual drug types for one particular company..
weeds
2016-12-05 16:04
So he showed currency,.. and we are restricting (only our market can create it)
weeds
2016-12-05 16:05
US $ are divisible and tradeable and can be consumed...
weeds
2016-12-05 16:05
Transaction submitted to blockchain- it got approved and pops up on te left... under assets (screen had assets, holdings and then working environment on right btw)
weeds
2016-12-05 16:06
Create holding- he had name , description, asset and count -- he created 2000000
weeds
2016-12-05 16:06
He created a holding in $'s which showed... and then created token
weeds
2016-12-05 16:06
Token allows you to validate participant.. this is a way to provision money to people and verify individuals
weeds
2016-12-05 16:07
So he then create sell offer-- Provision,.. we input the token in the amount of 1 and pay out amount of us $ of 1000...it can be executed once per participant
weeds
2016-12-05 16:07
Once it's committed, we have everything for our market/setup...
weeds
2016-12-05 16:08
He then showed another example with Baker-- provisioning a token and that's about it.
weeds
2016-12-05 16:08
we are going to create holding for $ tat the market put out and we will get us $ and create a new asset type of cookies

Questions:
weeds
2016-12-05 16:16
What is distinctive about Sawtooth Lake? This application is so generic and compare between the branches is a good way to go-- it sort of buys and sells anything in simulation. It's built as a generic proof of concept.
weeds
2016-12-05 16:18
*Comment from audience*- the thing I found interesting is the concept of transaction families.. It seems like there is some basic architectural constructs. Here is how you plug in consensus, here is communication protocols,. and with transaction families, give a blockchain a flavor. Here is type of data you want. So you have generic thing, you deploy it and can see stuff go around. If you want give it some flavor and use JSON formats- you can replace the ledger,.. or you can use the transaction primitives. The transaction family concept,... it turns it into a blockchain for x, y, z,.. without having to re-ode the primitives. This is an interesting differentiation....
weeds
2016-12-05 16:19
--> Fabric has that same infrastructure model, but the tooling and construction is better in Sawtooth lake,.. in chaincode, you can do anything you want, but this upper level model is very interesting and drive into Sawtooth lake,.. and if we can find common ground, we could execute it.. maybe make some tweeks on chaincode model. It's pretty cool

weeds
2016-12-05 16:22
In Sawtooth lake- marketplace is the transaction family-- which is asset types, how they get created, and how they transfer... Right now, it's programmed in Python.
weeds
2016-12-05 16:23
PNB Parabase team said- seems like types and structure.. there are similarities, but almost like a type in a language... higher level constricut
weeds
2016-12-05 16:24
User perspective comment- I like the popup box.. and I go into using Amazon and drop stuff in there, what Amazon is stuff behind the scenes, so i don't see latency. When i drop something in shopping basket, even though it takes days to get this done.. So what's going on ere is you are dealing with the biscotti, and I would try to do myself it would take me days to source and get msg back. But here,.. you see eventually consistency in minutes instead of days. I don't think people realize that blockchain is similar to Amazon and the real world.
weeds
2016-12-05 16:26
comment- there is in sawtooth core repo- there is an extension directory which you will find marketplace and navigator

Question: Does this provide any equivalent functioning as fabric, consensus? Or are we focusing more on fabric and this is a side project
greg_not_so

not sure if blockchain is Amazon like just yet. if i go out on the street and ask what each is and would probably get stares when asking for blockchain, while Amazon is a huge brand now

HI @jonathanlevi, The link you provided is old. This is where marketplace is now: https://github.com/hyperledger/sawtooth-core/tree/master/extensions/mktplace
weeds
2016-12-05 16:30
Brian indicated- There are multiple projects in Apache, and there are multiple projects in Hyperledger. We would encourage these projects to combine-- we would look for combination of services within to consolidate on one code base. We wanted the developers to work together and look to align. Sawtooth came out of Intel's work and came out with Proof of Elapsed Time. I'm keen to see example code and applications that novel approach for consensus. This is a slightly unpermissioned version of consensus. Hopefully what we can do in Hackfest and see how we bring them to converge or usefully differentiate. This is true for Aroha, Corda, and other projects coming in
weeds
2016-12-05 16:31
Last point I'd make- is marketplace something tied to sample code for Sawtooth,.. or does it make sense to split out in separate project so we could utilize for multiple DLTs? MAybe common UI and paradigm to deploy for different marketplaces?
weeds
2016-12-05 16:32
Intel: The front end code is totally portable,.. there are some like how transactions are formatted. The server would require change. Sawtooth has a validator and a rethink DB and python code that syncs between them so we don't send too many get requests to validator. I imagine that is very distinct to fabric.. with that said, I don't think it would be that much int he end.
weeds
2016-12-05 16:32
User: Could we get this working on fabric? Is anyone interested in doing the work? Everything under Apache license and suitable to explore on top of other DLTs.

This is a standard explorer- it has information about the blocks
weeds
2016-12-05 16:36
It shows the current state of blockchain (current hash, previous hash)
weeds
2016-12-05 16:37
Shows network information- names, addresses
weeds
2016-12-05 16:37
They are working on updating for 0.6- they did show a visualization which is performance, transaction rate, block rate, transaction per block , transaction per chaincode, and approved/rejected transaction (the last two are mocked, but everything else is real)
weeds
2016-12-05 16:38
Under chaincode- I have all these different chaincodes and developer friendly that is new to fabric- you can easily deploy -- it shows the code and constructs available.. you can do init and deploy the code... you can also run simple function--> transfer and added the arguments

Comment from audience: We don't have all the APIs clearly defined yet on how you would do that. so you could take approach. Here is the data you want to get out for version 1l0? From user perspective- here's what I want- connect to node,.. what chains that node has,... etc,.. if we can define that .. so we can keep those APIs backwards compatible. WE can start with that and get a document and share with others.

weeds
2016-12-05 17:49
The way that we group transacitons-- we handle finality on a per transaction basis. There is no block concept in consensus, but there is a logical construct.
weeds
2016-12-05 17:49
When you are performing consensus- it's not on transaciton itself,.. it's on the merkle root and is populated with the transactions themselves

What is Corda?
weeds
2016-12-05 20:38
Corda is a distributed ledger platform -- we don't say blockchain-- designed and built from the ground up to record, manage, and synch agreements (legal contracts) between identifiable parties, designed for regulated financial institutions. WE do think it's applicability is much broader than that
weeds
2016-12-05 20:39
It is inspired by and captures the benefits of blockchain systems without the design choices that make blockchains inappropriate for many bank scenarios.
weeds
2016-12-05 20:39
The question driving our thinking derives from simple thought experiment- what is defining characteristic of blockchain platforms that is relevant and valuable to financial entities.
weeds
2016-12-05 20:40
http://Corda.net has link to github repos, slack,.. and incoming days we want Corda accepted as an incubation project.

Mission- to establish the architecture for open, enterprise grade, shared platform for immutable recording of financial events ad execution of logic
weeds
2016-12-05 20:43
This is the first time we have systems built at scale for organizations who don't trust each other and bring together for shared set of facts through consensus and these technologies.
weeds
2016-12-05 20:45
look at all the financial companies that have separate systems and we spend 10 to 100 million dollars a year-we could save a massive amount of cost based on this technology
weeds
2016-12-05 20:46
Corda- it does not follow that the systems that taught us Bitcoin/Ehtereum that they solve the problems in finance. If a problem in finance is that counterparties in trade are in consensus and maintain consensus until the deal is committed.
weeds
2016-12-05 20:46
when you look at Bitcoin/Ehtereum when they existed back then- full broadcast happens which becomes a non-starter with financial use cases
weeds
2016-12-05 20:47
You have to be very precise who could validate, who gets the data-- this led us to Corda
weeds
2016-12-05 20:48
Question: when there is something manipulated of currency- was that notary became concept... or everyone has to see it if you act on it? The idea of a notary, which in reality is a generalization of the resource miners provided, you need to know who is authoritative if that record is updated or not-- the most current record (that's what miners do). You always need that and that is how notary came about. The original name was the "uniqueness service". It's really been there from the start.
weeds
2016-12-05 20:49
What is defining characteristic of distributed ledgers? Distributed ledgers- or decentralised databases- are systems that enable parties who don't fully trust each other to form and maintain consensus about the existence, status and evolution of a set of shared facts
greg_not_so
2016-12-05 20:51
consensus as balance confirmation? so, only one (counter-)party has to agree?
weeds
2016-12-05 20:51
There are 3 motivating concepts that we used with the membership so that our engineering is in right direction- can you bring people into consensus with a management of broad financial instruments? We chose cash, security (corporate bond), and derivative (credit/default swap). We worked through each one to ensure Corda met those use cases. WE also needed to bring people into consensus and evolve over time. We know that tey need to go consensus at state-- how do we come to consensus on one shared fact,.. and then try to scale up from there.
weeds
2016-12-05 20:52
The foundational object is 1) the state object-- piece of data that represents an agreement. Creates properties/fields from given financial agreement.
weeds
2016-12-05 20:52
Ledger is an atomic unit of data- that represents sared fact.
weeds
2016-12-05 20:52
STate objects always reference one or two documents.
weeds
2016-12-05 20:54
The first one is 2) contract code) verify that transfer (which) rule 1 (code) transfer (portal) rule 1(code)rule 2(code)-- this is constraint based programming.. minimal of whether an update to object is valid or not. You can offer as many of these in parallel and it's the narrowing piece of what has to be deterministic-- and this is where the security problems will be. This approach allows scale and running in parallel
weeds
2016-12-05 20:55
The other thing that is optional 3) we are trying to have real world agreements- no way you can model all the legal prose in code.. there will always be an overarching contract on how disputes are resolved. when you model contracts, you link to the overarching document... state object might be te master agreement between counterpart in documents ,.. "Ricardian Contract is composed of legal prose, parameters, and contract code"
weeds
2016-12-05 20:56
4) systems works with transactions- transactions enable transition between states- do the inputs exist ,are they current, and is it valid and inputs available
weeds
2016-12-05 20:56
We don't want to send the data to everybod- so we try to be very precise contract validity and contract uniqueness
weeds
2016-12-05 20:57
Inputs that are valid and outputs are valid- but you could have several equally valid contracts, and only 1 can be processed.
weeds
2016-12-05 20:57
You need to rely on someone you committed to in advance that it is a unique inputer to the system
weeds
2016-12-05 20:58
This is the notary- any transaction- it commits to which notary cluster is authority of whether output is committed or not and who is the authority.
weeds
2016-12-05 20:58
5) consensus is reached on transaction validity and uniqueness
weeds
2016-12-05 20:58
6) Flows defined for specific sent to each node/identity
weeds
2016-12-05 20:58
You see a lot of out of band messaging which goes to a subset -- and you see a huge amount that negotiate and agree ..or you see people using consensus for ephemeral workflow to simulate
weeds
2016-12-05 20:59
We overlaid flow framework to overlay the communication/negotiation and come to agreement before comitting to the ledger.
weeds
2016-12-05 21:01
2 of us want to update something- and we need a notary to be the authority
weeds
2016-12-05 21:03
answering from question- if you go back to model here- contract code can tell you whether transaction is valid or not-- if contract says only require one to sign,.. only one will sign,.. if contract says only require 2 to sign- then 2 to sign.. you model what has to be true. Things you might have is structural or validity of the entity. Both buyer/seller may have to sign it. For example secondary use cases- the financial instrument an option- you have a right to exercise a price to a certain deadline. What happens right before the expiry.. if contract you owner and seller to sign- and you could play a game and you lost your money.. so you have to have ability that certain transaction only require one to sign...

Does Corda consider notary a centralized single clusterized or is it a decentralized set of nodes for notary? Let's use the option
weeds
2016-12-05 21:06
Greg/Richard entered contract and Greg can execute at midnight. Richard wants to move from active to expired right after midnight.. and Greg wants to transition to exercise. Now you have a race and you have a time stamping issue. The actor of whether a transaction of the system- it is time stamping, you have to be the time stamp of the system (the notary)... The notary only signs if input object if it has not been consumed. the notary is saying- i will only sign that transaction if not the same input signed. And he will figure out and will sign if the appropriate time and within the bounds of contract. Notary is important for time and whether inputs are spent enough. In essence, this is what miners also do....
weeds
2016-12-05 21:07
We allow multiple consensus providers in the network... so for our option case, we trust a regulated market infrastructure and operated by CME for example. For another scenario for cash, the only authoritative of Barclays to be spent would be Barclays. We have multiple difference providers- some are centralized,.. some can be BFT... we have not implemented BFT notary. We have a raft one already
greg_not_so

are notaries miners?
weeds
2016-12-05 21:10
non validating notary will only have to remember the previous inputs and validate and read time stamp... reliability and privacy is a tradeoff. Is the notary is only looking at inputs and not validating the transaction. There is possibility for nefarious party can enter-- because that nefarious party has signed prior
weeds
2016-12-05 21:10
We have two approaches-- first, we have permissioned system, so we don't include malicious... but honestly people do make mistakes second, we do have a validating notary which validates itself...
weeds
2016-12-05 21:11
There is active debate of going with nonvalidating notary or validating notary--- there is a trade off.
weeds
2016-12-05 21:11
we are supporting both on same network
weeds
2016-12-05 21:12
Data model at heart of corda is immutable state objects and code governing the allowable transitions. You can look at a transaction to see if it's valid or not. by looking at notaries and you know which notary cluster- and whether the transaction is confirmed-- so we seperated validity from confirmed as a result.
weeds
2016-12-05 21:13
I talk about the replicated machine and UTXO model-- this is on the UTXO model side of the debate. this is how we can parallelize the system and see the diagram of states- it's how we get to the best privacy system without advanced crypto
weeds
2016-12-05 21:13
Q: is the contract code bilateral? So all the examples i give are billateral. but contracts can be with large parties. So for a transaction to be valid- there could be 10's of 100's party to sign it and you can specify what sigs are required.
weeds
2016-12-05 21:14
You might have one contract in system for cash- and millions of cash records that represent banks- these have to be significantly tested.
weeds
2016-12-05 21:15
Q: what happens in event if contract code is updated? these references are by hash sha256 hash. so what i'm talking about design. when you look at state object, it may be com.r3.com.cash and then another class with the same name... you would still have the hash,..
weeds
2016-12-05 21:17
how do you upgrade? there is a contract upgrade - this batch of states get to upgrade to cash version 2.. you can't change the data- you can only evolve what you have... in addition, who must sign? it may be advantageous ---who must sign to upgrade the contract.. so think about the DAO-- this could be hard.

Example: Cashpayment
weeds
2016-12-05 21:24
i started with oject of Barclays with 100 pounds and proving someone else that Shipping company is owed 100$
weeds
2016-12-05 21:24
We do a transaction- we construct a payment that consumes the 100$ i had and creates 100$ for shipping-- do the balances match, is it the same issuer barclays on the input, because i no longer have the money am I the one that signs the transaction?
weeds
2016-12-05 21:26
xyz ends up with this transaction- it is an object, richard signed and owed 100$ by barclays.. all shipping company is richard said he had 100 pounds and it has not previously spent.. and here is a valid transaction.. you don't have the chain of custody back to barclays--- here is the set of objects and barclays owes money--i also have to send transaction tat the transaction was issued to me-- i have to send precursor where it was issued to me- it's the chain that provides that proof that it was actively conveyed to me.
weeds
2016-12-05 21:26
Q: how do you get privacy/confidentiality if you have to share all the chain of custody?
weeds
2016-12-05 21:27
we look at this in depth and what we got to -there are 5 pieces to this? why does this not degrade to full broadcast?
weeds
2016-12-05 21:29
technical side is things we have address randomization... but then you bring legal/regulatory part of this. Richard has this cash that he has at barclays and signed that... you can do that from one to two hops-- but you must do this-- the chains don't get that long for cash- so you only have to provide the narrow part for the ledger. the issuer has to countersign the transaction or are they ave to go further and reissue it. You can actually snip the chain regularly if you use the UTXO... the issuers will require needing multiple notaries.. and we need to do a lot to be compliant with regulation. As technologists, we need to make it clear the strong downside at this point- only when you have common notaries... so if everyone has to notarize gets less interesting .
weeds
2016-12-05 21:31
Can a transaction generate an output with a different notary from the input? Yes absolutely.. I have some cash that is committed to Barclays and IBM stock to IBM notary... I have a problem if I want to swap cash and stock.. I can do a 2 phase commit and IBM notary to work with Barclays notary. I will support a notary exchange -- create a transaction that only requires one notary.... you could still do both if you have to.

The design is not for all use cases- it's based on trying to solve specific problems, but the design is pretty baked and feel it's quite baked. the code base is very young, but the quality is quite high.

Richard: Until we open sourced- it's hard to have those conversations-- Corda was not visible unless you were members. Sharing components will come sooner-- Corda targets JVM-- we minimized the part that to be deterministic.. and we are creating whitelist sandbox to keep deterministic. I suspect there are implementations on BFT that we can benefit from.. there are other projects.. I have a theory (not R3) the utxo and replicated VM model- i think they are different. they solve different problems. I see a world where we converge to a permanent UTXO model and permanent VM model. It's not obvious to me that the code base to one makes sense
weeds
2016-12-05 21:36
Q: with replicated VM and replicated state- we can try to do un-natural thing.. Statements have been made that no technology met these needs before. There is a lot of common architectural that ended up this way. The notary is at trusted service that is out there- and fabric has ordering service. There is a notion of channels and privacy similar to the R3.. there is a lot of commonality. Maybe we do that separate.. would be great to talk

2016-12-05 21:40
there are real use cases where there is some threshold where stakeholders- we all collectively agree or 90% of us plus a regulator agree that we may want to take this off the chain and white it out,.. and remember we whited it out and not remember what is there

This first came out with Chameleon Hash- they implemented this and not sure it's in hyperledger code.
weeds
2016-12-05 21:41
In the mean time Norbloc suggested a similar implementation. Brian suggested that it's worth thinking about- you have to have 100% of the stakeholders agree or 2/3 majority or whatever- it's still immutable "ish" and might be able to use in regulated environments where we need things like right to be forgotten
greg_not_so

abcd were the block 1 transactions
weeds
2016-12-05 21:49
So essence proposal-- introduce a transaction that happens sometime later-- we propose a request for transaction in the later block can holds all the data and modified view of the data.. after confirmed by enough # say 100.. it issues that transaction and confirmed by large # of blocks- then we have all the transactions except the modified transaction which has the same trust/same level of security
weeds
2016-12-05 21:50
To be more technical- each blockchain has it's own implementation details.. in our whitepaper, we described on bitcoin blockchain.. for bitcoin blockchain- you can not arbitrary modify transaction, because there are links between the transaction such as inputs and outputs. the only part that you can modify --- each blockchain will have to maintain how modifiable the transaction will be.
weeds
2016-12-05 21:50
If we specify that certain part of transaction is authorized for deletion from very beginning and we don't sign for authorized for deletion..then that is the process of modification.
weeds
2016-12-05 21:51
Surprisingly, I learned fabric 1.0 is implementing exactly that. we are not the only ones thinking about that-- our solution based on fabric is more suitable... we can comply with the right to be forgotten.
weeds
2016-12-05 21:52
Binh then speaks up-- the evidence of the prviate transaciton, but the actual data is not on the transaction. In fabric, we have a parameter on the protocl called transient. so applciation in this case can pass in private data and then hash that data or do whatever to get the evidence into the transaction.. that allows me to put the evidence on transaction parameters. it will be part of the endorsements,.. but the endorsers could drop the transient data on the transaction. That is a current implementation which is available in master today.
weeds
2016-12-05 21:53
Q- as far as I understand for those nodes that still hold the data- only the nodes are allowed to hold that data can keep that data... but at some point, when that data of the personal data of bonds-- customer may execute right to be forgotten and wants that data to be deleted... so you are introducing delayed transaction type
weeds
2016-12-05 21:53
Binh- now it's part of the chaincode, or it's part of the application.
weeds
2016-12-05 21:54
Q- We are in a project with google and we have a different way of handling this- the database stays immutable, that data is marked that it is no longer viewable, but you can't really delete it- is it not more elegant with permissions versus removing transactions
weeds
2016-12-05 21:55
Norbloc- that depends- do you include it in the data in database or not... that is the problem of the definition. if it was in original transaction- some party will hold that data,.. even if it's separated from main blockchain.. someone has it. those parties are holding it- they will look at all of that data-- But not for each party...
weeds
2016-12-05 21:55
We are not pretending there are no transactions
weeds
2016-12-05 21:57
Gari- I'm not saying whether i argue for or against. But that being said, the problem- you can have database access permissions- record exists or not-- but there is nothing that chains the records together. The only way you validate the history of ledger is to have all of the ledger. Anyone has access to the ledger- so you can't give permissions on that.
weeds
2016-12-05 21:58
So it's a sublte difference.. that's exactly what happened- facebook never deletes data and google doesn't either,. just prevents access. The feature -- the notion is if you have mechanism in place- it's a data distribution- whether peer to peer. normally here is my content, hash on blockchain, and content is distributed some other way. the concept here is you have a distribution mechanism and you pop that into the distribution mechanism but only keep the hash of it on there.. the hash is what's hashed in the blockchain-- and it's a means to distribute that data.. in that case, we can delete it from the database or delete access. the ledger is still valid because you have the hash.
weeds
2016-12-05 21:58
So what if law enforcement undelete the deletes-- "the right to undelete" (chuckling)
weeds
2016-12-05 22:00
In a decentralized system- i own the peer- i can alway s decline that this transaciton is removed.. how do you enforce this?
weeds
2016-12-05 22:01
the only way is you do it through regulation-- and then there are penalties if you don't do it.
weeds
2016-12-05 22:01
The only way you can detect that-- you can never do this on Ethereum or Bitcoin networks...
weeds
2016-12-05 22:02
(more discussion) Blockchain is immutable- you would have to - come down and mandate and fine that you have to delete this data, is this going to invalidate the blockchain? The bank has to do it by regulation,.. so the big concern is does this invalidate my blockchain?

Hi all,
I was trying asset_management using Fabric v0.6.
I have a chaincode that's already deployed. I need to be making calls to it, and it checks whether the caller is allowed to carry out such actions, using `stub.ReadCertAttribute(...)`. However, when I try calling that method, following the example given in `asset_management_with_roles_test.go` I get an error saying `[chaincode] Launch -> ERRO 074 You are attempting to perform an action other than Deploy on Chaincode that is not ready and you are in developer mode. Did you forget to Deploy your chaincode?`
This is despite the chaincode being deployed.
Any idea as to what am I missing here?

@daniellee - looks like you are trying to use the same certificate for both peers? The easiest thing to do what be to concatenate the CA public key with your public TLS key and use that as the certfile for your peers - `cat ca.pem tls.pem >> tls.pem`

In the example given at https://github.com/hyperledger/fabric/blob/v0.6/examples/chaincode/go/asset_management_with_roles/asset_management_with_roles_test.go, the deploy method is bound to the chaincode setup by the `go initAssetManagementChaincode()`, right?
What I have is a set of chaincodes that need to be run one after another, and I need to test for ACLs on one of them. This would require that I deploy multiple chaincodes. How do I go about it, following the asset_management_with_roles_test.go example?

Chris said- the question becomes where can we think about areas that are overlapping where the concepts are not orthogonal to one another.
weeds
2016-12-06 16:00
Richard (R3): You covered a lot of ground. Some things that caught my attention. Things from Corda that might be relevant to others and areas of common work. And possibly what to do on interoperability. If I start with membership services- what is the solutions underpinning Corda. We don't use permissioned or permissionless as it's overused term, it is a identified network given the legal prose. We need to know who is communicating on network. What we have implemented is the network map, which is a service . The network map is simple service- it's a lookup service and it comes back the organization and their addressable network. Certainly more to it than that,,.. signatures and chain certificates. How do you get into that? You need an enrollment service- I suspect what you have in membership services. The requirements have is that we have workflow- here's who I am and proof of who I am and evidence that is necessary and there has to be a certiifcate authoritywhere humans validate this. My sense is that you are doing that with Membership SErvices,.. and if so, we can collaborate on it.
weeds
2016-12-06 16:01
With the other way around- we designed Corda- the mass majority of code is not consensus critical. There is a core of code that has to be deterministic. The verify function does true or false,.. and everyone must come to same conclusion. For JVM, it's in experimental branch that the idea is whitelist sandbox of JVM- where we explicitly allow or don't allow operations . We whitelist libraries and do rudimentary work so that everyone runs execution and halts at the same place. Anyone else that is trying to implement JVM for fabric possibly? That code is probably relevant.
weeds
2016-12-06 16:02
The third point is interoperability- we did a lot of work on interoperability. The conclusion is that interoperability at abstract- you can have lots of whiteboarding. interoperability only makes sense with business services.. Technically maybe it can. Can a ledger solution- can it be working with a financial application? This is how you get into two phase commit, escrow,etc,.. This has to be done based on real validated use cases to drive the true interoperability.
weeds
2016-12-06 16:04
Where do I think this is heading? I could be wrong on what I have about to say- I'm still fundamentally- I feel there is two seperate architecture-- pure UTXO and pure replicated VM- UTXO is a datacenter approach.. Key consensus process is synch and clear verification process. Replicated virtual model- some abstract computer.. and mathematically.. They are very different. I feel there will be one implementation of each where each has it's own use case. I could be wrong certainly on this.

2016-12-06 16:05
Murali from DTCC: I don't think technology aspects but concern about - can you at least converge on nomenclature aspects? It's about how many of these do we keep adding? Can we log/merge towards? otherwise for new members, it's just too confusing- so many platforms. if you don't agree on common aspects, it's too hard for users. It's not about technology, but we should agree on higher level aspects

Tamas from DAH: We offer a start of thinking about how we could eventually think about common foundation layer.. First, explains how it fits in financial services domain, and it is not in contribution of stacks that represent on stage. We need concrete feedback and this is how we advance this discussion.
weeds
2016-12-06 16:07
Richard from R3: We've identified requirements formally that we needed to implement. Those that read the technical whitepaper that are very influenced. WE would welcome if everyone would be doing that
weeds
2016-12-06 16:08
Tamas: You might say you reject, but I'd appreciate -- before we introduce another stack, let's make an attempt. The architecture working group made very good suggestions. Those stacks go into those stacks is a statement of are they aligned and how do they plan to align- otherwise we will continue to onboard stacks and this does not align with requirements group, papers presented by us, I fear that this is just becoming a collection of unconnected things.

2016-12-06 16:11
Ethereum: I just joined in August, but we are working on nomenclature and semantic ontology to capture the terminology ideas that are being expressed in blockchain community. Is one being run on state machine? Is it gas oriented? We are trying to address that. Blockchain explorers-- it can be driven down to apis, so we are working on nomenclature speaking about yesterday, whatever stack is being propose- there is value in having multiple stacks -- I think it's all very valuable One advantage about Ethereum- many languages used with Ethereum. Two proposals are bieng talked about web3J will help java users interface with system. The other advantage is a very large user base and if you are looking to validate evidence based use cases.. ethereum is that it has test net and efs... there is a large support system for that. My goal to be ere is to learn what people are doing and what they find important. I'm impressed that there are consensus algorithims being proposed. I'm impressed with IROHA consensus algorithim and Corda consensus algorithim.
weeds
2016-12-06 16:13
individual: Maybe what are key requirements and start with that possibly? How many use cases they can support-- I want something that works and stable. If there are things that can extend. But we are all defining now,.. noone is going to have anything by tomorrow. We need to have a pluggable architecture- for that use case, we can plug in the pieces. The biggest question - are we going to do apache module with a lot of incubation- or start with what covers the most use cases. Requirements help a lot with this.

You can certainly talk about features. One of challenges we have and correct me if mis-characterize. I suspect everyone looked at what we published in January... and then so focused on exclusively on what everyone is doing. and not seeing,.. if you look at pivot in June- there is a lot that is quite similar in fabric. If we had conversations earlier on- maybe we would have converged. I think it's good to get these tings out in open. Let's take stock and step back and see what is in each of these- Sawtooth, Ethereum, Corda and reflect on that. Everyone is pushing for delivery, but take a step back and this is a function (the doorman or whatever you call it)- we don't need too many of these. Maybe something more oriented for permissioned network or someone who can just doll out certificates- maybe subtle differences . If we understand what else is happening beyond our own projects,.. I think tat Brian vision. I don't think it will happen overnight.

Gari: what related to that and what Jonathan saying- it would be one thing if projects came back with 100's of people and bunch of people using it. This is what happens in Apace and there is competing ones. The problem is that we have projects and have 5 people developing them.. and now community of people- and we are competing with people to contribute. If I was an outsider,

trying to integrate 2 pieces... could I hack out the Corda notary service and throw in our ordering service- I could have done that, but would that even serve a point? we see questions from community- when do I use when? A contest of who is best to serve is not productive. This is a waste of time. My point- could we coming out of here.. maybe a tag team of contributers. could we put together a group of 1, 2, 3 proposals of something we would like to prove out as a concept. Hey- I will code over the holidays and will contribute to this. Pick something- pick a real project- guys, is this actually possible? I think there is an interesting idea - taking Poet and using leader election for our ordering service in fabric and extend and do pure validation for UTXO-- use POET that dynamics leader and run CORDA and Sawtooth Lake for it?
weeds
2016-12-06 16:21
Tamas: Why? we would do something technically-
weeds
2016-12-06 16:22
Gari: Why poet? we can use common component-we are doing permissioned network. Corda and Fabric have come to similar conclusion - ordering or notary service to make sure no double spend and ordering. We both ended up to CFT to start with or single process... you guys use RAFT, we used KAFKA with Zookeeper and both are Crash Fault Tolernat. What if we want more people to enter and be trusted- POET would allow for a larger set and still trusted. There are real cases for that.

Tamas- According to my experience for financial services- the least sexy thing is consensus server.. this is not the thing you would pick.
weeds
2016-12-06 16:23
Gari: your assumption is it's just financial services
weeds
2016-12-06 16:23
Gari: we can either be financial services or not- I do know them too- I have a world of other people that are not just financial services who require these things.. Please pick a project.. if we do membership services- let's do cop or something here.
weeds
2016-12-06 16:26
Chris: there are use cases beyond financial services such as the one Gari described- There is internet of things tat is going to scale and no bank will scale to that. That might apply to teller machines- not banks exchanging between. The more important reason is to get people to work together we have to get something out of it. I'm not going to work on it as a do gooder, but I derive from going down to soup kitchen and helping out. So when we think about- what does it take to get parties to collaborate or they are being forced to do it? In open source, it's all voluntary. I would just sort of say- we need some common ground- maybe that's not the highest priority - it's at least a thing,.. membership services or doormat,.. that's another thing that we could potentially common shared value. Then there are some aspects- like consensus models like BFT beyond CFT that require significant amount of research, investment, experimentation , trial and error, and if we go about independently, we won't solve problem quickly- if we collaborate, those will be important to experiment together. Things like zero knowledge proof is so hard, so better off if we do it together

Jim Zhang: we should collaborate, but I don't think that the direct conclusion is we should have multiple projects

weeds
2016-12-06 16:29
Jim Zhang: i want to play devil's advocate-- it's not good to have duplicate. Everyone agrees is that Java as a project is huge success. If you look at enterprise hybernate and Java E-- both had huge communities behind them and co-existed. They inform each other on approaches and collaborate on pieces of the spec proposals. Each project needs to be serious about what they say- each should have community and resources behind them so growing up and fulfill meaningful projects and requirements... and we can inform each other. Maybe we have two - but two need to be successful.. not 5 where some have real resources and some not. They claim to be part of group..
weeds
2016-12-06 16:29
PNB Paribas Having more resources does not make successful project.. You can work on something that is utter failure if you go down wrong path. Listen to other people and work in the working groups. One person could bring something more of value.

2016-12-06 16:33
Richard from R3: I remember a time web application server- Websphere/WebLogic. Big process to standardize Java Enterprise. It was insane. I could be wrong on this- it's premature standardization before app servers were going and where the real issue was going. And we had too top down to force these competing stacks ,.. and community rebelled-- Spring and Hybernate came on side given EJB too complicated. The lesson learned is the race to converge was a mistake- maybe I learned that lesson and why I stood back and not converge too early as a result. The other experience - the code base itself when we get into fully open for R3 is that we have a consistent coding style. I worry about doorman- I worry about the architecture and take other pieces wholesale and how do we maintain the integrity. this is a case o maturity and what maybe we need to get over. Two other quick points- you made people. DAH is not the only ones- they are the only irm that don't throw code over the fence,.. this is what we want existed. final question on Gari- I think we can focus on deterministic JVM and Membership SErvices. We are not fully open. OUr full JIRA- these are the things we have not started designing or buildling.. No answers there.
weeds
2016-12-06 16:35
IROHA: we need not to be waterfall- these are important to be iteratively and follow a spiral model. Collect your thoughts and so it's useful to do projects like Gari said- do something simple technical demoes, but after that has to be focused collaboration- these are the results of what worked and did not work. it's important not to be too binary in decision making process and dive in and take small pieces as much as possible. this is what we have been focusing on as we are working with 3 main projects right now- and all different fields so hard to get collected in one big picture.. slowly be able to expand to other use cases. this is approach we've been taking.

2016-12-06 16:37
Chris: I'm going to give analogy of auto industry- building the are once a month.then large scale manufacturing. Each auto manufacturer was creating their own thing- complete design from bottom up and so all the cars from automaker were different. over time, there is an ecosystem that expanded and specialization on tires on how to build tires that are heat resistant or cold resistant or whatever. There were only so many tire manufacturers required- so now you only have the tire manufacturers that they are shared. Ultimately there ended up only 3 or 4- my point is this- the auto industry was independent and essentially it's all a big blur.. and only thing different is how sexy is it.. how green is it or whetever, but the piece parts are all common. How do we do that? how do we accomplish that?
weeds
2016-12-06 16:39
Brian: cars are very different, but snow tires are different than tires designed for speed- while they are similar- 4 tires on most cars and steering wheel is common- there are technologies and the implementations diverge.. they converge were value and where economic advantages. it depends on 50,000 foot view or 10,000 foot view. would auto industry converge on day 1 or phase of experimentation that led to get the more aligned. the enterprise java bean is a good example of trying to over enginner and ram down people's throats, but better architecture was how they grew organically. I feel your anxiousness, but we do need to converge services and vocabulary.
weeds
2016-12-06 16:44
Cisco- this is exactly what we have tried to do with the architecture group. The end vision there is to specify the functional requirements-- define identity services, define smart contracts, define policy and crypto and storage layer. We've been specifying the interfaces to them instead of implementation details.. that way you have options within those layers ;.... Gari: take a simple example of Ethereum. Everyone takes that as the spec and go write that and build multiple version of ethereum. You can have multiple clients-- you deploy your code, but that is their mission and spec. Who are we trying to help? You can either be an umbrella that brings in projects, but when projects come in and ask community for help. That's not scalable.. Unless you are growing community- you are just bringing in more things that compete with the same stuff. the one trend that i've noticed is there are a lot more people working on things and are now trying to use the products, but not contributers to product. So we have people who brought original stuff-- but you battle for potential resources, we don't all get everything done and confuse people. R3 originally had a great mission- it was a clear statement- we are here how blockchain is applicable and provide recommendations. if that's the point of hyperledger project or key things everyone needs to have.. then that's fine, but that's different then here are projects how implemented, here's our resource pool, it's never going to work- we will have same 5 people... and someone is going to be upset with one project and go work on another. Who is this for? *richard R3* We have 5 different code bases. The actual enemy - everyone is committed. This has to be developed in open- as this has to be sticky-
weeds
2016-12-06 16:48
Richard R3: financial institutions need to look at market dynamics- but maybe we help them understand deploy on open base. my bet is they won't succeed because clients too small. We should not lose site- the building of canals in UK- emergency civil engineering competing and how did they resolve- formed organization of civil engineers and yet parallels - it doesn't mean we have to slam these things together. CISCO: we are in experimental phases of what niche, what requirement. What richard is pointing out- it comes out in the open. different transport protocols- some of them will be good fit and some will be better at others. We are still at experimental phase and diverse set of requirements and we are in early stages of the game. We have a set of buildling blocks that will be sanitized over time.. I don't think we should standardize everything and too early to standardize. CHRIS: there are aspects of function regardless of framework- or do we build 5 or 6 or 8 of those- maybe we build 1 or 2

Richard R3: You may good point- nextgen consensus. We did read that. But we did not caught up. It's different not better or worse. We did study that in depth. If someone pitch the architecture- probably not as a TSC member pitching all of these. Each of those being able to do that and what would help- this should be able to be a prerequisite.. you mention the explorer,.. because of architectural explorer, we are buildling things .. i've not taken enough time.. people have read the whitepapers and understand the code base of each others stuff.

Brian: Are the resources finite? as I talk to people joining- don't expect existing people to jump onto your project. there are some ethereum companies that have paid attention, but have made their strategic investment- maybe bringing ethereum project in gets them more engaged. If we are talking about efforts- how do we get most productive output? even if time is finite, we can grow the pie and grow the community-- everyone pays attention to what we do... I do think this is sharing as much information internal where we have common needs and building common interfaces,.. and Richard's proposal the architecture working group and whitepaper working group. I'd be willing to maintain a queue from raising hands.

Tamas: We have different appetite for the two phases. some people we are still exploring.. that's the danger I see and stretch the direction of experimental and increasing the pool. I'm concerned for several reasons- there is a community that is bigger- and it could have a reverse effect. I don't see it beneficial to consolidate on a project that is aimed to provide solution for enterprise use. I don't see how a working group will continue to progress if you connect with public and decisions are made in a different way and in a different forum.

Mural from DTCC; We can compete and bringing platform- maybe increase the components - Corda or Fabric - we have a component repository and create platform to publish those components to this repository.

Jim- we should not be in rush for consolidation at this point. what we should do is this is very early days for blockchain. Meaningful projects can grow and the market will sort it out. But there is a concern- people are confused.. what can i do with these 5 or more. we can help them tremendously for each project- what they are and what they are built for and more helpful what projects have already been using it and to what level o success.. we don't have anything like that today. as an organization we need to form opinions about project . what is POET good for? what is PBFT good for? what is Kafka good for? we don't have anything like that.. everyone reading each of these independently-- how do I chose? Hibernate sprint was so successful because they spent time making sure it's easy for developers to get started. we need to do that for audience and simply for developers.. even the c level people- we have enough of information on these projects on how to chose.
weeds
2016-12-06 17:02
DTCC: consolidation might not be the right time- but certainly for collaboration. IN similar way- there may be some components that may be useful-- it may not make sense completely, but ways to generalize it-- and something we ought to get started. Speaking right now,.. one is go, one is java , one is C++.l how we use those components l maybe we can independently utilize it.. but even things like smartcontracts supports many languages. Shared reusable components

My 5 cents on the discussion.
As an app developer I see the blockchains as the operating systems. Nowadays in the world of OSes if I want my app to succeed, I either write it in the interpreted language which can be run on as many OSes as possible (Java, Python, JS) or as a slightly outdated approach I would write it to be 100% POSIX-compliant.
I would be more than happy if there existed a shim layer which I can use without knowing what is the underlying blockchain. Something that abstracts the concepts of smart contracts, state, transactions, membership service and presents it as a unified interface to me, the app developer.
Maybe I am asking for too much. Or too early :slightly_smiling_face:

@yuwei if you are programming on fabric today, most immediate would be 0.6, but 1.0 will soon be in a state of Beta in 2017

(1) I generate different certificates for 2 peers.
(2) I tried the method you mentioned but I got another error when I start the peer program
`2016/12/07 01:00:46 Failed to create ehub server: Failed to generate credentials crypto/tls: private key does not match public key`

Hi everyone, we are http://IDAMA.LK and are looking at digitizing the supply chain of construction materials in developing countries. Would love to connect with people doing something similar. We wanted to leverage blockchain to retain anonymity to the user's while interconnecting them for supply chain purposes.

just to add it to the log here
Today, Shahan Khatchadourian from ConsenSys presented the Web3J project, a proposal submitted to the TSC, and talked about Nethereum. Both projects allow Java (and .Net, respectively) developers to integrate their existing apps with contracts deployed onto an Ethereum blockchain. Both projects allow developers to interact with Ethereum platform components such contract deployment, accounts, transactions, signing, IPFS, as well as client-specific features (for geth and Parity).

Question: If I want a fairly stable commit that coincides with the current documentation, is there something you can point me to? I'm trying to do a proof of concept for an academic project and I've spent a depressingly long amount of time over the last week just trying to get one example app to work (to no avail). :flushed:
muralisr

@yevot are you using the master or 0.6 ?

Hi all , need help
I'm trying to implement a pbft consensus. Configured 4 nodes on different computers, all 4 nodes have the same core.yml conf :
validator: enabled: true
consensus:
# Consensus plugin to use. The value is the name of the plugin, e.g. pbft, noops ( this value is case-insensitive)
# if the given value is not recognized, we will default to noops
plugin: pbft
# total number of consensus messages which will be buffered per connection before delivery is rejected
buffersize: 1000
events:
# The address that the Event service will be enabled on the validator
address: 172.17.110.234:7053
# total number of events that could be buffered without blocking the
# validator sends
buffersize: 100
# milliseconds timeout for producer to send an event.
# if < 0, if buffer full, unblocks immediately and not send
# if 0, if buffer full, will block and guarantee the event will be sent out
# if > 0, if buffer full, blocks till timeout
timeout: 10
# Peer discovery settings. Controls how this peer discovers other peers discovery:
# The root nodes are used for bootstrapping purposes, and generally
# supplied through ENV variables
# It can be either a single host or a comma separated list of hosts.
rootnode: 172.17.110.237:7051 ,172.17.110.234:7051 , 172.17.110.236:7051, 172.17.110.238:7051
# The duration of time between attempts to asks peers for their connected peers
period: 5s
Chaincode deploys only in rootnode. After that if i try to invoke , other nodes throw exceptions cause they have no chaincode deployment.
I tried to change peer discovery settings: All 3 nodes discover only the root node, and vice versa. Nothing changed.
What could be the problem ?

@muralisr thanks, I'll give that a try. If I just switch to v0.6, will that match with the current documentation?
muralisr
2016-12-07 04:04
yes
yevot
2016-12-07 04:05
that's probably what I need to do. can't believe I didn't think of that quite a while ago
muralisr
2016-12-07 04:05
http://hyperledger-fabric.readthedocs.io/en/latest/starter/fabric-starter-kit/ that would be a good place to start
yevot

I was trying to follow that but using the master branch. Man, that wasted tons of time
muralisr
2016-12-07 04:06
ah .. oops
yevot
2016-12-07 04:06
but I think you helped me get back on track so thanks a bunch, @muralisr
muralisr
2016-12-07 04:07
but if you already have master it may not be a bad idea to give this a whirl https://jira.hyperledger.org/secure/attachment/10242/simple_test_with_skeletal_peer.md
muralisr
2016-12-07 04:07
but upto you… if you are going to be developing a project of sorts using this, might as well do it with 0.6

when I deployed the chaincode, it looked like it spit out a thousand lines of like.. octal (e.g. \254D\241\332\370\365#i\375\375\371\373\363\367\347\357\317\177\326\347\377\027\000\000\377) but then it went ahead and created a block so i guess it worked
muralisr
2016-12-07 04:19
did it say “Commit..” on the peer console ?
yevot
2016-12-07 04:19
yes, "Commit success"
muralisr
2016-12-07 04:20
ok
muralisr
2016-12-07 04:20
try `peer chaincode query -n mycc -c ‘{“Args”:[“query”,”a”]}’`
muralisr
2016-12-07 04:21
its not there in the doc but should work
yevot
2016-12-07 04:22
yep, worked. Query Result: 100
muralisr
2016-12-07 04:22
ok
muralisr
2016-12-07 04:23
just make sure you see commit on deploy and invoke before you test the previous step
muralisr
2016-12-07 04:23
queres are not submitted
muralisr
2016-12-07 04:24
ie, any request you make using `peer chaincode query ..` is not submitted for transaction
yevot
2016-12-07 04:24
i think i need to jump back to 0.6 so i can figure out how to get my application to talk to it and have a little bit of reference, but I'm glad you helped me get master functional!
muralisr
2016-12-07 04:24

What defines a block - Is it one transaction or multiple transactions?
manikandan.kannan
2016-12-07 04:54
I am new to BlockChain Technology and i have been reading many articles around it but still pondering over the basics
kansi
2016-12-07 04:55
manikandan.kannan one or more transactions can form a block
manikandan.kannan
2016-12-07 04:56
ok, so does the implementation of the block chain technology like fabric, bitcoin decide whether its one transaction or multiple transaction?
kansi
2016-12-07 04:57
yup
manikandan.kannan
2016-12-07 04:57
ok
manikandan.kannan
2016-12-07 04:57
Does the block contain the data or only the hash of the data? If it contains the hash alone, where is the data actually stored?
kansi
2016-12-07 05:00
that depends on the implementation
kansi
2016-12-07 05:00
you can refer to bitcoin docs to get an idea of this
kansi
2016-12-07 05:00
it can give more detailed picture than I can
manikandan.kannan
2016-12-07 05:01
ok, how is it done in fabric?
kansi
2016-12-07 05:01
i am not a fabric core dev
manikandan.kannan
2016-12-07 05:01
okay
manikandan.kannan
2016-12-07 05:02
Do you know the role of CouchDB in the HyperLedger Fabric project?

2016-12-07 05:02

In block chain, the term distributed is actually not distributed in the true sense whereas its actually replicated. Is this understanding correct?
manikandan.kannan
2016-12-07 05:03
everywhere i see that the every node in the network has its own copy
manikandan.kannan
2016-12-07 05:03
this means the same data replicated across? if a network has 50 nodes, then 50 copies?

2016-12-07 05:15
@manikandan.kannan yes, 50 nodes means 50 copies. the data is replicated but the *control* is distributed (at least ideally)
manikandan.kannan
2016-12-07 05:16
@yevot so when a new transaction happens, its first validated and a block is created, then added to the block chain....who adds to the block chain?
manikandan.kannan
2016-12-07 05:17
The same data residing on all nodes mean that any new transaction added to the network would have to be replicated across. The data grows as the number of transactions increase. Is the entire block chain broadcasted to all the nodes in the network? If that's the case, the network cannot scale. Is this the case or only the new block is broadcasted and every individual node adds to the copy of the chain it holds?
irvingnam

yevot
2016-12-07 05:18
if I understand correctly, transactions are sent, are validated by peers, and are eventually grouped into blocks that are added to the block chain
yevot
2016-12-07 05:19
only the new transactions and validated blocks need to be sent around the network, but every node should have an identical blockchain (that's the idea)
manikandan.kannan
2016-12-07 05:20
ok so when you say sent around the network, who takes care of doing that?
yevot
2016-12-07 05:21
the nodes interact with each other. i think _how_ that's done is dependent upon the implementation and i don't know exactly how fabric does it
manikandan.kannan
2016-12-07 05:22
and everyone having a copy means that there is requirement for anyone to have a basic Hard disk space to store data
manikandan.kannan
2016-12-07 05:22
if the number of transactions increase then data grows and the block chain size grows
yevot
2016-12-07 05:22
right
yevot
2016-12-07 05:22
i think that's actually a concern for the bitcoin network
manikandan.kannan
2016-12-07 05:23
oh ok......but i think hyperledger may solve that by means of couchB
manikandan.kannan
2016-12-07 05:24
BigChainDB also seems to be doing that...where the DB is distributed in the true sense like mongoDB but at the same builds the BIockChain characteristics on top of it
manikandan.kannan
2016-12-07 05:26
so here the entire block chain is not replicated but only a subset is replicated....this means anyone can potentially tamper the data as long as they have access to DB cluster which they would....may be they solve the problem of immutability etc by different mechanisms
gonght
2016-12-07 05:26
has joined #general
manikandan.kannan
2016-12-07 05:27
the concern is also for any new node adding to the cluster...becos if every node has to maintain a local copy then any new node should get the copy first
manikandan.kannan
2016-12-07 05:28
this is expensive....but you may not have this problem if the node does not have a copy
manikandan.kannan
2016-12-07 05:28
@yevot your thoughts?
yevot
2016-12-07 05:29
with a db with shards, i'm not sure how you would have a full blockchain
yevot
2016-12-07 05:29
from the genesis block to the latest transactions
yevot
2016-12-07 05:29
seems like nodes would have to make pretty wide assumptions
yevot
2016-12-07 05:30
but I'm not sure. the project I'm trying to use fabric for has a very sequential nature so having a node with an incomplete history would be very bad
manikandan.kannan
2016-12-07 05:30
ok
manikandan.kannan
2016-12-07 05:31
@yevot do u know the role of CouchDB in fabric?
yevot
2016-12-07 05:32
i don't
manikandan.kannan
2016-12-07 05:32
ok
yevot
2016-12-07 05:32
i actually don't know a ton about fabric but i've been trying to work with it and have the general idea about blockchain
manikandan.kannan
2016-12-07 05:32
sure
manikandan.kannan
2016-12-07 05:33
@yevot When a codechain is added by a peer to the network, is the CodeChain added to all the nodes in the network? When a transaction happens, where is the CodeChain get executed?
manikandan.kannan
2016-12-07 05:34
first of all i am not clear where the code will be executed? is it on all nodes or one node or subset
manikandan.kannan
2016-12-07 05:35
if it executes on all nodes then similar to the hard disk requirement on all nodes...every node should also have specific run time requirenent
yevot
2016-12-07 05:36
when transactions occur on that chain, they have to use that chaincode? so that governs the logic, i think. the actually processing happens on a node and then validating peers confirm it's correct? but i'm guessing here
manikandan.kannan
2016-12-07 05:37
yes chaincode is kind of an event trigger as per my understanding
yevot
2016-12-07 05:37
right, every node needs to be able to execute the chaincode to be a part of that chain (or even in a specific group of nodes, maybe)
manikandan.kannan
2016-12-07 05:38
sounds interesting
manikandan.kannan
2016-12-07 05:38
another aspect is the order guarantee
manikandan.kannan
2016-12-07 05:38
this is interesting especially in immutable state
manikandan.kannan
2016-12-07 05:40
if 2 transactions are submitted to the network then how is the handled....i.e. if 10$ transfeered from A to B...now A has 0$
yevot
2016-12-07 05:40
yeeeeah, i really don't know order works. bitcoin must've figured it out. perhaps the first with the proof of work determines the order?
yevot
2016-12-07 05:40
yeah, the double-spend problem too
manikandan.kannan
2016-12-07 05:41
intersting
manikandan.kannan
2016-12-07 05:41
finally, is there any fabric dev group who can answer the questions
manikandan.kannan
2016-12-07 05:41
?
yevot
2016-12-07 05:42

I am new to fabric, but since no one has responded to the original message I will try.
I do not see a way to query previous world state from chain code. The alternative that I see is to treat the values of keys as arrays that you append to each time you want to have a new value for the key. The array would give you a history of values for the key.

However the first `make all` command failed with `SyntaxError: Unexpected token =>` on the arrow operator. The setup has Node version 0.12.7.
Any idea what's missing here?
chaitanya
2016-12-08 06:12
@arnabkaycee
I'm not very sure of this myself, but have been trying this for some time and can help from that experience.
Assuming you're using TCerts as given in the asset_management_with_roles examples, `stub.ReadCertAttribute("role")` should get you the role of the user calling the chaincode as specified in the yaml file.
synblockchainteam
2016-12-08 06:18
@arnabkaycee , Have you mentioned user with role in membersrvc file and enable aca = true. By enabling this it will add attribute in TCERT and you will able to retrieve role of user.

Hi All, … I’m currently investigating how to potentially get involved/start contributing to the community with a quite sizeable company. Initially the involvement should be relatively light-weight. One idea I had is they could simply get involved in hosting a distributed ledger. Do you think that would be realistic? And what would be a good way to approach this?

2016-12-08 12:32
@ramvi #general you can ask questions, but really most of the fabric experts are on the fabric channels and the pieces are componentized- so for example for consensus the experts are using fabric-consensus-dev . For security/crytpo, they are on fabric-crypto, for ledger fabric-ledger-dev, for gossip protocol fabric-gossip-dev... and then there is also fabric-sdk. There is one general channel called fabric-dev as well
weeds
2016-12-08 12:35
@cburgdorfer we would really welcome the help and a lot of companies have really been coming together to contribute to fabric. So, I think it depends on what expertise your company brings and how you want to contribute. If the deeper data level pieces are more your expertise- I would reach out to fabric-ledger-dev and see where you can contribute. There is a lot of code to be written,.. or tests, or documentation,. as well as hosting to consider. Where people typically start is trying to just bring up the fabric and play with it and then start contributing to the code. I would ask on the fabric-ledger-dev channel to see how you could help... again there are other channels, but that is what you were pointing to, so why i suggested that.

@cburgdorfer When I was at the Hackfest or other events, here is what I have observed and can share. There are people that are hosting the fabric, but certainly the most active commercial opportunities are companies or startups that are developing applications. So one example is Everledger who I think I saw go into production on provenance with wine fraud-- this is the website that they pointed to https://www.winefraud.com/ . There were also a lot of companies at the Hackfest that are working on applications in the financial, health, government sectors that were described to me. Also, there were a couple of companies that are more like servcies companies that had trained individuals on how to develop on top of fabric who were consulting with many other firms.

Our vision: “a truly distributed web with public and private chain lattices built on honest node network chains”
We would love to host and support HyperLedger community in SF through our collective. We are working on scheduling some brown bags in Jan with industry experts. Discussions will be around learning, bootstrapping and evangelism.

Please let question.
Will you be able to plug pow and pos in the future? Also, if that is possible, I think that using membership service is not absolutely necessary. Or is it necessary for membership service? Also in the future.

@ashwini look at the error message. you probably need to `vagrant destroy` the old VM and delete it out of virtualbox too before you can rebuild the new one. i had that error a few times too and clearing it out solved it

Hi all, I am using a Windows machine and am having issues making the docker images for fabric in Vagrant. The "make docker" command fails because of busybox.
mkdir -p build/busybox-1.25.1
curl -L https://www.busybox.net/downloads/busybox-1.25.1.tar.bz2 | (cd build/busybox-1.25.1; tar --strip-components=1 -jx)

perhaps it is corrupted? *Possible* reason follows.
bzip2: Inappropriate ioctl for device

It is possible that the compressed file(s) have become corrupted.
You can use the -tvv option to test integrity of such files.
You can use the `bzip2recover' program to attempt to recover
data from undamaged sections of corrupted files.

I was able to edit the busybox Makefile to fix the above error by downloading the tar.bz2 with wget and then running the tar command separately (without using the pipe command). However, the busybox-1.25.1.tar.bz2 itself contains a Makefile, and when that runs, we get the following error:

make: *** [build/busybox-1.25.1/busybox] Error 2
As an interim fix I have reverted the changes from https://github.com/hyperledger/fabric/commit/b61723f9ddcc91cafd4f3a8c3634bd8d32388b32 (essentially removing busybox) but I need a more permanent solution going forward

@nandini.parimi The documentation you are looking at is written for the v0.6 version of the code. The master branch is v1.0 code which is a work-in-progress. If you check out the v0.6 branch you should be able to make it through the instructions in the documentation you referenced. E.g. membersrvc has been removed in v1.0, replaced with a component called COP, and moved to a separate repo, fabric-cop. And I'd reckon as well that the *peer network* command has been removed from v1.0. Alternatively, if you wanted to try something out against the master (v1.0) code, check out this document. https://hyperledgerproject.slack.com/files/muralisr/F2VH7C78S/simple_test_with_skeletal_peer.md but be aware that as v1.0 is being constantly updated, so if you have trouble with this simple 1.0 test you may wish to check with the author to see if he has an updated version of the document. Hope this helps.

Hi, I want to ask about the actual propose of using SystemChaincode.
We found that, adding our chaincode together with the systemchaincode improve the overall performance.
So, the questions..
1. Should we use systemchaincode instead of usual way to deploy a chaincode?
2. Is there any negative impact that we might need to be aware of?

@gokulamurthy the problem can be
1. You did not deploy any chaincode before querying or invoking.
2. You use an incorrect chainhash. So, you need to pass the recent chainhash when you do query or invoke. Once you deploy the chaincode, you will get an associated chainhash. And if you modify the chaincode, you will always get a new chainhash.

do you know if your process.env.CORE_CHAINCODE_ID_NAME is the same as "04233c6dd8364b9f0749882eb6d1b50992b942aa0a664182946f411ab46802a88574932ccd75f8c75e780036e363d52dd56ccadc2bfde95709fc39148d76f050"
stylix
2016-12-11 04:28
the very long string is actually your chainhash, so you need that set to your CORE_CHAINCODE_ID_NAME
jmahhh
2016-12-11 04:29
I'm actually using the REST API at the moment and just copying the chainhash into `name` for the invoke and query functions
stylix
2016-12-11 04:29
I don't know how you set it, in deed I never run SDK.
jmahhh
2016-12-11 04:30
right
stylix
2016-12-11 04:30
usually, you can pass that chainhash value with REST

ignore the different chainhash it's from another test
stylix
2016-12-11 04:33
you need to make sure that your deploy chaincode and your passing chainhash is exactly the same
jmahhh
2016-12-11 04:33
I'm 100% sure
stylix
2016-12-11 04:33
e.g. you deploy and get 2d8f48b88f308db12cb3a15da5862f44803ca1a3dc5aa9b1c46a4d9f19c14667461eac3e256a6786a7f2cfecc97aa799aefd055045ea14179a3885b3fbc0bbeb, then you invoke with the same string
stylix

alright, then it's a bit....

jmahhh
2016-12-11 04:41
yup
stylix
2016-12-11 04:41
strange
stylix
2016-12-11 04:42
can you check the chainheight, it might not equal
stylix
2016-12-11 04:43
you might need to wait until all the nodes reach the consensus before querying/invoking
stylix
2016-12-11 04:44
also, you need to check if all the nodes have it's own chaincode attached
jmahhh
2016-12-11 04:45
hmm how do I do that?
stylix
2016-12-11 04:45
some node might have some problem that chaincode do not successfully deployed
stylix
2016-12-11 04:46
docker ps, and see if you have 4 peer running, and 4 dev-xxx running
stylix
2016-12-11 04:47
btw, you run 4 nodes right?
stylix
2016-12-11 04:48
maybe i'm wrong, I don't know how you run up the network
stylix
2016-12-11 04:49
usually, I have vp0_1 ... vp3_1
stylix
2016-12-11 04:49
you may check the other node as well
stylix
2016-12-11 04:50
I'm not sure how possible, if you run only vp0_1 anyway

@donjohnny uploaded a file: https://hyperledgerproject.slack.com/files/donjohnny/F3CJXCEP3/invoke_always_returns_ok.go and commented: Hello all, can Invoke return a message to the client? I'm returning errors but the rest reply is always OK, what am I missing?
garisingh
2016-12-11 12:26
@donjohnny - You will not be able to return chaincode errors directly back to the client. Invocation is asynchronous - the only errors you'll get back would be things like malformed payload, security issues, etc. But if the invoke is "accepted" by the peer, it will respond with an OK and then submit the transaction to the rest of the network (hence why is asynchronous). You have the option to use the "event hub" feature to listen for blocks / transactions and at that point you will be able to see any errors. You can check out the examples in the NodeSDK ("hfc") in order to see this in action

Hi!
I'm Shannon Foster from the developing blockchain educational project, http://HackBlockchain.com. We've been hosting blockchain educational meetups throughout the entire Mid-Atlantic. Working to build an army of Blockchain masters.
I read that this group was launching a blockchain ecosystem program. I'd like to help out. http://HackBlockchain.com has hosted events in 4 different states since launching in November. We have more events being scheduled for Puerto Rico, Johannesburg, Philadelphia, and more. Let me know how I could be of service.

Does somebody used this function? Thanks in advance.

Hi guys I'm working on a new fabric project, and I'm doing my first cloud application - I'm looking for some advice on what consensus options I have with these considerations: 1. Need one network node on an AWS server 2. Several developer machines connecting intermittently on the network

I just learned we've had an IoT test device running non-stop through the IoT Platform to a Hyperledger Blockchain Fabric v0.6 on Bluemix since 26 November at progressively increasing traffic levels. It started at 2400 txns/hour and increasing twice since then to today's pace of approximately 6500 txns per hour. The blockchain has increased to 148,000 blocks with half of that in the last week. The IoT senior developer will continue to enhance and improve. Next stop v1!

[Quick Question] Can I get caller's secureContext in Chaincode? (Hyperledger 0.6)
I checked the implementation of GetCallerCertificate and GetCallerMetadata, they always return nil?
// GetCallerCertificate returns caller certificate
func (stub *ChaincodeStub) GetCallerCertificate() ([]byte, error) {
return nil, nil
}
// GetCallerMetadata returns caller metadata
func (stub *ChaincodeStub) GetCallerMetadata() ([]byte, error) {
return nil, nil
}
humblealex
2016-12-13 05:03
@daniellee Maybe you are using the old version of 0.6. Mine says // GetCallerMetadata returns caller metadata
func (stub *ChaincodeStub) GetCallerMetadata() ([]byte, error) {
return stub.securityContext.Metadata, nil
}
arnabkaycee
2016-12-13 05:05
Hi people, I found out the following method to obtain caller metadata from Java chain code. --> `stub.getCallerMetadata()` in *fabric-sdk-java* But the problem is it returns byte array. Can anyone tell me how to decode this byte array to get the caller details? Any help would be greatly appreciated. Thanks.

Run v0.6 with 4 vp (docker), noops consensus. When I invoke the example02 chaincode, one of the peer (random) execute it twice. Anyone have the same experiences?
sk
2016-12-13 07:19
Well, even with 2 VP, if I do invoke multiple times, sometimes one of the peer run the chaincode invoke function twice. The bad things is when I run query, it will run randomly on one of the peer and resulting different value returned.... Is this a known bug or what?

Every time I changed my chaincode, pushed to git and deployed again, IBM Blockchain return me a new chaincodeId Hash, even I only changed code from "Query". That means I lost all blocks where linked to previous chaincodeId. If it is in Live environment, we can not afford the data lost when we want to upgrade or fix bugs. Is there any solution for this?

@rafael.turk yes, the Hyperledger Fabric team has done some performance measurements on our v0.6 release, though not with the current master in development... without security, I believe that the numbers I saw were in the 400-500tps range with 4 nodes running pbft without encryption on x86. I don't recall the numbers from the Z/Linux team, though I expect that they have done similar tests

@nandini.parini a git clone by default will check out the master (v1.0) branch. you can get v0.6 with ```git clone *-b v0.6* ....``` from either http://gerrit.hyperledger.org/r/fabric or from http://github.com/hyperledger/fabric

@nandini.parimi see above command (I did a typo on your userid) but without those asterisks....that was a formatting error.... i.e., *git clone -b v0.6 https://gerrit.hyperledger.org/r/fabric* should get you the v0.6 code

@joshhus S stands for *Simplified* as in Simplified Practical Byzantine Fault Tolerance (there are some who are lobbying for SPBFT to be used as the acronym)
joshhus
2016-12-13 21:56
There's a Scalable BFT out there in the literature, so SBFT as Simplified potentially in conflict. ... Is keeping PBFT an option and just explain ours as Simplified.
silliman
2016-12-13 22:03
@joshhus well if you Google 'SBFT byzantine' the top hits for SBFT come up as Simplified, so the conflict already exists. But it beats googling 'SBFT' by itself, in which case the top result was 'Small Bowel Follow-Through' :stuck_out_tongue_closed_eyes: Seriously, anything's possible but your best best to get this changed may be to convince the consensus developers over on #fabric-consensus-dev

@

sk
2016-12-14 03:51
@zhoupeiyuan Currently I couldn't find tag/branch for 0.7 on gerrit/github.
After 0.6 perhaps the first logical plan was 0.7 so there's could be some mention on config, doc, etc.
But now the plan is 1.0 for Mar next year, so I guess 0.7 will be skipped. Unless there's change of plan.
The master branch is still in flux. Unless you don't mind handling with more troubles.
So I suggest, as @silliman comment above to use v0.6, i.e. "git clone -bv0.6 ..."

@ashwini, btw you could not vagrant up both at the same time as they are using the same vm name "hyperledger". Either vagrant destroy the one your not using, or change that name on Vagrantfile.

@sarkoi yes command is same , everytime fired vagrant destroy or sometime manually deleted

2016-12-14 12:30
@ashwini, the vagrant up command, basically after creating the vm, will run provisioning which is devenv/setup.sh as a root (which is installing docker, etc). So, why don't you try to run that manually to see where the error occurs.

After getting feedback from the community, I have modified the community Jira boards to filter off of components instead of labels. Please use one and only one component when creating your user story, task, etc. Using a single component will simplify boards. If you feel that you have a story that spans squads / components then its good singn you should open a separate Jira item.

Hello All , I have question about finality in hyperledger. In all the presentations about hyperledger talk about Transaction immutability but the examples that I have seen is that we can add and update a record with in the world state. in such case I believe that we can trace back who update what through audit trail. is there some examples around it . Any help is much appreciated here
somashekar
2016-12-15 09:10
Other question, is about loading the data into the hyplerledger. are there any best practice on importing the data in the hyplerledger ?
bfuentes
2016-12-15 09:18
@somashekar about audit, you can have a look on the blocks, it is signed by a user. Otherwise, you can trace the logs of the chaincode, if it is just for simple audit. Or finally feed an historic via an external service.
bfuentes
2016-12-15 09:19
For the importing data, normally you call “init” function at deployment with args. The WorldState is stateful, you need to store static data, I advise you to point to another external DB

somashekar
2016-12-15 13:48
@bfuentes , Thanks for the response. You mean to say for the application level audit we need to have external service ?
somashekar
2016-12-15 13:50
@bfuentes , Sorry I could not completely understand your answer. I have a data to be loaded to my chain code in the order of 500K . Is there is any best practice available for the data load ?
colyerfs
2016-12-15 13:53
Are there any Fabric commands to reset the network and clear the data? I'm looking for a way to clear my test environment easily in between test runs
bfuentes
2016-12-15 14:04
@somashekar it depends what you mean by “audit” . You have also a role ‘auditor’ if you want to give more access to a particular user
bfuentes
2016-12-15 14:05
@somashekar Best practice to load initial data is to use the function “init” at deplyoment, passing arguments
bfuentes
2016-12-15 14:05
your arguments can be a big json object for example
bfuentes
2016-12-15 14:06
or a plain text csv
bfuentes
2016-12-15 14:06
anyway is a “string” what you can pass
somashekar
2016-12-15 14:12
@bfuentes , Let me simplify my question , I have chaincode which is custid, name and address . this is deployed. now it is deployed and I need to load data to this chain code with 100K records .
somashekar
2016-12-15 14:13
@bfuentes , Are you referring to Init of the chain code ?
bfuentes
2016-12-15 14:14
yes, when you deploy chaincode u can point to a specific function on the chaincode
bfuentes
2016-12-15 14:14
this is the initialization
bfuentes
2016-12-15 14:14
chaincode is Logical code, is not custid,name and address
bfuentes
2016-12-15 14:14
what you call is a transaction
bfuentes
2016-12-15 14:16
you can do it easily with docker-compose
bfuentes
2016-12-15 14:17
docker-compose -f myfile.yaml down
bfuentes
2016-12-15 14:17
otherwise delete dockers containers
bfuentes
2016-12-15 14:17
and relaunch all manually
bfuentes
2016-12-15 14:17
or by a script

Hello - this may be a very stupid question but I'm struggling to understand security in hyperledger/fabric and this is my understanding:
1 User X have to register into network supplying valid id and secret
2 After that he can perform operations supplying the enrolled id
3 1 and 2 are not correlated in any way other than 2 have to be after 1 so any user Y that know that X is enrolled can impersonate him
This does not make much sense to me - so what am I missing?

It looks like you haven't supplied a username there. You need to supply username by using the `secureContext` field in the REST json. See this https://github.com/ChaitanyaKr/learn-chaincode#deploying-the-chaincode
shalinigpt
2016-12-16 10:15
So can i register username as my name ?
chaitanya
2016-12-16 10:16
No, you'll have to pick a username from the membersrvc.yml file. For example, `jim` or `lukas`.

I think you've cloned the master branch, looking at your directories. You should pull the v0.6 branch instead.
shalinigpt

chaitanya
2016-12-16 10:23
Yes, a fresh pull for the v0.6 branch
shalinigpt

I only see a v0.6 there: https://gerrit.hyperledger.org/r/#/admin/projects/fabric,branches
shalinigpt
2016-12-16 10:31
Can you share a cmd
chaitanya
2016-12-16 10:34
This should do it: `git clone http://gerrit.hyperledger.org/r/fabric --branch v0.6`
You could verify by running `git branch`

var hfc = require('hfc');
var PEER_ADDRESS = "http://172.25.64.31:7050";
var MEMBERSRVC_ADDRESS = "http://172.25.64.31:7054";

@jonathanlevi thanks, may I know where to start learning GO language

Sure. Try each of these (to give you a taste of a “full book”, an intro, and some web-based “playground” for quickly typing/running stuff, respectively:)

@rascal The chaincode is failing to build. See these errors in your Docker logs: ```---> Running in 67eac64ac4e1
src/build-chaincode/utils/utils.go:5:2: cannot find package "http://github.com/hyperledger/fabric/core/chaincode/shim" in any of:

That error is caused because you do not have the Hyperledger Fabric source in a `vendor` folder next to your chaincode.

Hi guys, one question about membersrvc.yaml. For application that hold many valid users, how could they be registered? Is it need to update eca.users section of membersrvc.yaml dynamically? Or any other approach to implement this?

Newbie question -- why does Hyperledger Fabric on IBM BlueMix only offers 4 peers? Why not more than 4? (Ala Ethereum?) And I need to pay 10k for just 4 peers?
rafael.turk
2016-12-18 18:28
HI All.. I’m running 4 notes.. Just for fun I’ve stoped one of them and let the remaining 3 continue to work while I’ve placed a few transactions.. Now I’ve resumed the stoped node.. however It still stuck in a previous block height . How can I synchronize it with the rest of the group?
scottz
2016-12-18 21:40
That is not necessary. Actually, the node is likely running fine; the counts will jump forward occasionally (depending on configuration paramters), although the counts on that peer will simply lag for potentially a very long time. However, if you stop a different node, and continue sending transactions, then that one will sync up with the good two very quickly.

When using the IBM BlueMix, does anyone know if you can download the code for the Dashboard Monitor so that you can make changes to it for your own use? Or is the Dashboard Monitor only available within BlueMix?

Hello all, sorry for the silly question but I remember seeing somewhere in the docs that the REST API is deprecated? I can't seem to find it now but I'm wondering why it is deprecated? Is it because it only has a subset funtionality of the node SDK?

my project team is finding the best way to work with the chaincode inside the blockchains..
ibmamnt
2016-12-19 05:58
My understanding is the rest api is removed from "core", but the team is now thinking about to have rest api server build on top of SDK. Still under discussion. See this as a reference:
mrbuggy
2016-12-19 06:48
@ibmamnt thank you for replying! "core" did you mean a specific version of fabric?
ibmamnt
2016-12-19 07:14
@mrbuggy I meant version v1.0 alpha "core" to be released. The rest api will be there in v0.6.1 release.

if err != nil {

@vanio - are you including the `attrs` parameter requesting the `role` attribute when issuing the TCertBatch - https://github.com/hyperledger/fabric/blob/v0.6/sdk/node/src/hfc.ts#L1105 and https://github.com/hyperledger/fabric/blob/v0.6/sdk/node/test/unit/asset-mgmt-with-dynamic-roles.js#L185

@garisingh no. I'm calling enroll() and invoking a smartcontract on the returned user. I'd like to handle attributes inside the smart contract
vanio
2016-12-19 18:58
I guess I have to call getUserCert() before invoking the smart contract. Right?
garisingh
2016-12-19 19:00
correct- else the transaction cert used by the client will not include the attribute(s)
vanio
2016-12-19 19:02
Thank you. I'll try that. Do I need anything else configured. I was thinking I need to have TLS enabled in member services for ACA to work. Is that necessary?
garisingh
2016-12-19 19:02
nope
garisingh
2016-12-19 19:02

vanio
2016-12-19 20:22
@garisingh I still can't get it working. I have the getUserCert call right after enroll, but even with it succeeding I keep getting the same error when I call query/invoke
vanio
2016-12-19 20:23
I see something different in the example you sent me. The certificate is passed as parameter to the smart contract in it. While in my code I'm trying to verify an attribute of the user invoking the chaincode
vanio
2016-12-19 20:25
this is all my chaincode in question:
vanio
2016-12-19 20:25
} else if function == "test" {
certAttr, err := stub.ReadCertAttribute("role")
if err != nil {
fmt.Printf("Error reading attribute 'role' [%v] \n", err)
}
return certAttr, nil
}
vanio
2016-12-19 20:26
I'm trying to return the role attribute of the enrolled user invoking the smart contract

Can someone confirm my basic understanding of gRPC? So for now, it is used by HFC Node SDK for birectional communication with the validating peers. Then gRPC is used again for bidirectional communications between Peer and chaincodes?

@gokulamurthy You can not use identical user for both rest and HFC Node SDK. User enrollment info is stored in so called wallet. It is current limitation that one single user can store wallet in single location at this moment.

Thanks for the reply, can i logout the user who already logged in through REST api
vanio
2016-12-20 10:15
@gokulamurthy No, you have to use different users for HFC since it uses a separate key value store. If you login with a user through CLI or REST it will not be stored in HFC key value store and login for it will fail
vanio
2016-12-20 10:21
btw I managed to resolve my problem with attributes. I had to deploy my chaincode using CLI and specify the -a flag. I was trying to deploy from HFC and it doesn't seem to support specifying attributes for the deploy request. Is that so or I have missed it somewhere?

if err != nil {
return nil, fmt.Errorf("Failed retriving details : [%s]", err)
}
var rows []shim.Row
for {
select {
case temprow, ok := <-rowChannel:
if !ok {
rowChannel = nil
} else {
rows = append(rows, temprow)
}
}
if rowChannel == nil {
break

@mike_dircz Hi Mike I suspect you are running into a very common problem whereas the documentation you are looking at is written for the v0.6 version of Fabric but if you don't explicitly clone or checkout the v0.6 branch, you will get the master branch of Fabric which is the v1.0 in-progress code. e.g. if you do *git clone https://github.com/hyperledger/fabric* or *git clone https://gerrit.hyperledger.org/r/fabric*, either of those will get you the v1.0 Fabric. If you are new to Fabric and trying to get up to speed on it I'd suggest you get the v0.6 code. Try *git clone -b v0.6 https://github.com/hyperledger/fabric* and the instructions you're looking at will work better.

silliman
2016-12-20 19:49
@mike_dircz Hi Mike, normally as part of the build process the binaries for *peer* and *membersrvc* are placed in ....fabric/build/bin . It's possible that the documentation you are looking at is in a section where it assumes you use vagrant to provision, which will put that *build/bin* directory in your path. If you are using another method, e.g. docker images or building native, you may get past this by updating your PATH accordingly or invoking it out of there..... okay, on the post you just made.... the build/bin directory will not be built until you run *make peer* or *make membersrvc* (or any other make target that has a pre-req target for peer or membersrvc)
mike_dircz
2016-12-20 19:53
I am using the docker images
name63
2016-12-20 19:54

mike_dircz
2016-12-20 19:54
ok, i will check that
mike_dircz
2016-12-20 20:04
This is how I got the docker images
Pull images from DockerHub
First, pull the latest images published by the Hyperledger fabric project from DockerHub.
docker pull hyperledger/fabric-peer:latest
docker pull hyperledger/fabric-membersrvc:latest
Running the Peer and CA
To run the fabric-peer and fabric-membersrvc images, we’ll use Docker Compose. It significantly simplifies things. To do that, we’ll create a docker-compose.yml file with a description of the two services we’ll be running. Here’s the docker-compose.yml to launch the two processes:
membersrvc:
image: hyperledger/fabric-membersrvc
ports:
- "7054:7054"
command: membersrvc
vp0:
image: hyperledger/fabric-peer
ports:
- "7050:7050"
- "7051:7051"
- "7053:7053"
environment:
- CORE_PEER_ADDRESSAUTODETECT=true
- CORE_VM_ENDPOINT=unix:///var/run/docker.sock
- CORE_LOGGING_LEVEL=DEBUG
- CORE_PEER_ID=vp0
- CORE_PEER_PKI_ECA_PADDR=membersrvc:7054
- CORE_PEER_PKI_TCA_PADDR=membersrvc:7054
- CORE_PEER_PKI_TLSCA_PADDR=membersrvc:7054
- CORE_SECURITY_ENABLED=true
- CORE_SECURITY_ENROLLID=test_vp0
- CORE_SECURITY_ENROLLSECRET=MwYpmSRjupbT
links:
- membersrvc
command: sh -c "sleep 5; peer node start --peer-chaincodedev"
Save that in a directory with the name docker-compose.yml. Then, run docker-compose up to start the two processes.
name63
2016-12-20 20:16
yes, and that works
name63
2016-12-20 20:16
oh, i guess you just don't get how to run "peer" command-line tool?
name63
2016-12-20 20:19
am i right?
name63
2016-12-20 20:21
since you are just using prebuilt images, obviously you don't have peer binary at your localhost, so you have two options: 1) compile it; 2) login into vp0 and use command-line from there
name63
2016-12-20 20:23
following second option, exec 'docker exec -ti mynet_vp0_1 /bin/bash' to run bash in the container. mynet_vp0_1 is the container name in my host, but it can be different in your case
name63
2016-12-20 20:23
and there you can run peer deploy, peer invoke, etc
mike_dircz
2016-12-20 20:24
I'm a novice AND YES you are right, I don't know how to fun the "peer" command-line too. I'm following the directions as defined here, but I keep getting stuck when they don't work.

hi "hame63" thanks for the help. running the peer command-line tool with your directions is working
silliman
2016-12-20 20:48
@mike_dircz Yes @name63 's advice is solid for when using the Docker images, and while the first couple of sections in the URL you gave have sections for "vagrant" and "not vagrant", it seems like the section "Running the CLI or REST API" isn't as clear with regards to vagrant vs. non-vagrant ....
silliman
2016-12-20 20:50
@mike_dircz name63's advice is one way to go about it- log into the container and execute the CLI commands from there. Alternatively, from your local host, you should be able to execute the REST APIs because your docker compose file has exposed port 7050 (among others) from your docker container to your local host. What isn't made clear is that for the *peer network login* command, you can use the REST API shown just below it as an *alternative* to the *peer network login* command....
mike_dircz
2016-12-20 20:50
correct the directions are note clear. And i'm finding some errors in the commands as well.
mike_dircz
2016-12-20 20:51
i will try the REST APIs once the command lines are working
silliman
2016-12-20 20:52
@mike_dircz so two options are, login to the container as name63 suggested and issue the CLI commands from there, or, from outside send the REST APIs to localhost:7050 ... it looks like the doc states that REST API is an alternative to the CLI for chaincode deploy, invoke and query, but for the network login it doesn't clarify that they are alternatives
silliman
2016-12-20 20:57
@mike_dircz actually this general channel is sort of intended at a Hyperledger level which includes other projects besides Fabric (e.g., Sawtooth Lake, Iroha, etc) so if you run into other roadblocks you may consider posting it on the fabric channel - at least until somebody there asks you to take it to a more specific fabric-* channel :slightly_smiling_face:

@alexjipark It indeed is a bit lengthy. You see it crash, then you check the logs, and at times the message may not be as informative either, when I search for the error in the source to get some idea about what caused it.
Perhaps someone else has a better way of going about it? :thinking_face:

@alexjipark They are trying to improve some of the logging content in January on Fabric. I suggest going over to fabric-dev channel though as I know the teams are watching this channel that work on Hyperledger-fabric.

Hi! Can someone tell me where can I create a bug/PR for `hfc` npm package? I'd expect https://github.com/hyperledger/fabric-sdk-node but it's clearly outdated - v0.0.2 while published package is v0.6.5
shrike
2016-12-21 21:26
`package.json` for `hfc` npm-package contains incorrect `typings` value, it should be ` "typings": "./lib/hfc.d.ts"` instead of `"typings": "hfc.d.ts"`.

@zainx01 Looks like there is no guide in the doc. You might want to ask #fabric channel what kind of issues are there to obtain assistance (though it is Christmas season, most are taking off).

@comicocean I don't know which Hyperledger projects you are utilizing- but for fabric there are many channels. The general one for fabric is fabric-dev. Then they break down from there with experts int he different areas- all channels start with fabric,.. and there is a consensus-dev, crypto, gossip-dev, ledger-dev, sdk channels (again all starting with fabric-).

@abhinav.garg i think it would be much easier to start with the docker images that you can find here to start doing some experimentation: https://hub.docker.com/u/ibmblockchain/ . Because I wasn't clear on your question in terms of block size nor do I know what all companies are doing, i do know that with the version 0.6 version, there are companies that at minimum have 250,000 blocks with 1000 transactions per block running in production.

2016-12-23 12:18
@milkeg I do not know of a formal comparison between Hyperledger-fabric and Corda. There also is version 0.6 and version 1.0 of Hyerpledger-fabric. For Corda, they have published a whitepaper on line you could google. For the version 1.0 for Hyperledger-fabric, you could look at the following: https://wiki.hyperledger.org/community/fabric-design-docs.

vinshu
2016-12-26 11:25
I then go on to register the chaincode

you fabric is running in development mode and in development mode you have to specify the name of the chaincode instead of the path

Is it possible to make external service calls from chaincode? For example, if I need to lookup the current exchange rate or today's temperature using a public API how can I make that call from the chaincode?
If external calls are allowed then there is a chance of each node providing a different output (non-deterministic behavior). So how will consensus be reached?
abhinav.garg
2016-12-27 04:29
Could anyone explain car lease demo in brief ,as from where API being called and from where web services being assigning for fetching
umasuthan
2016-12-27 04:38
@abhinav.garg, Theoretically speaking, external service calls are possible to make from chain code. However, that is definitely not recommended as it may render the hyper ledger inconsistent. One of the promises of hyperledger is replicability, i.e., given a world state, if we re-execure all txns in the same order, we should arrive at the same end state of the ledger. If we use external service, and if the service calls fail, or if the service calls returns different values at different point of time, we will end up rendering the shared ledger inconsistent and eventually there will not be any consensus among the peers (as each peers’ ledger copy is in different state). This is my understanding.

I am new to chaincode development. i have previously worked on Ethereum based dapps with contracts coded in solidity

From what I see in examples, there are Getstate and Putstate functions that we can use to write/read key value pairs to Ledger
vinshu
2016-12-27 10:03
Now if I need to save complex structured and objects, how can I do that???
vinshu
2016-12-27 10:03
Also is there any official API reference containing all chain code functions that I can refer??
umasuthan
2016-12-27 10:07
@vinshu, you can. Shim provides API through which you can create tables, insert, update and delete data. They are not relational tables, but more like object store.
vinshu
2016-12-27 10:08
Do you have
vinshu
2016-12-27 10:09
@umasuthan Do you have the link to the documentation??
vinshu
2016-12-27 10:09
And Is updation possible on ledger. I thought it's immutable
umasuthan
2016-12-27 10:16
You can refer to the samples. If you have cloned the fabric project, you can refer to the sample at /github.com/hyperledger/fabric/examples/chaincode/go/largerowsiter
That has table operations. I was given to understand that under covers it uses Getstate and Putstate functions
Coming to the immutability part, updating data is possible. However, the trail of transactions is immutable. Again that is how I have understood. May be someone can correct me.
sibelius
2016-12-27 10:25
@umasuthan I can’t find `largerowsiter` on fabric repo on github

@sibelius, I think we have have the key of one table as a column in the other table to represent relationships. However, i don’t think we have impose referential integrity constraints. Those are to be handled through code.

Can a Fabric Peer host many Personas?
For example, a shipping company deals with many truckers as contractors. Must every trucker run their own peer, or can a single peer handle many truckers _as if_ they were independent peers?
muralisr
2016-12-27 16:10
@ruslan you might want to take a look at the cop interactions in SDKs (say node sdk)
muralisr
2016-12-27 16:17
@suranap that’s really a decision of how you envision membership on the chain. e.g, if the chains “supplychain” with supplier, banks, ports, exchanges etc… you can imagine the trucker as a user on a “supplier” peer. On the other hand if the chain is a “monitor truck” chain (stretching a bit here to make a point :slightly_smiling_face: ) you can imagine truckers running their own peer
muralisr
2016-12-27 16:18
^^^ basically begs the question “what is my chain’s purpose ?"
suranap
2016-12-27 16:22
If a trucker is a user on a “supplier” peer, can they still sign transactions with their own keys, keep their data confidential from other truckers, etc? Or is it all mixed in under the supplier’s credentials?

@suranap to state it simply a wide variety of possibilities (but what you ask would be possible). Details on how this can be managed depends upon the application (client side and chaincode). fabric-crypto would be the channel for details (although I expect it’ll be quiet for a few more days)

@sibelius, I checked the error message you posted, ISorry, got confused. You are compiling a V0.6 compliant chaincode with V1.0 fabric library.
The signature of the Init method is as below for V 0.6
Init(stub ChaincodeStubInterface, function string, args []string) ([]byte, error)
If you fabric is V1.0, the it will be as below:
Init(stub ChaincodeStubInterface, function string, args []string) ([]byte, error)
Check what is the Init signature you have in your code.

@umasuthan in application developer's guide under "writing building chain code" it is asking to follow "development environment setup" , which is same in fabric developer guide also. are those the same??? in fabric network setup there is option for docker images pull request and gerrit pull. which pulling should i use? for the record, I am using ubuntu and don't want to use vagrant.
umasuthan

@mpravatranjan, If you are planning to develop chaincode, you can follow the steps to set up you development environment using Docker images for deploying/testing code. If you are planning to contribute to fabric project then you can follow the steps to set up the Vagrant environment.

Hi All - new to the project but have a basic question regarding data persistence, security, recovery etc. that I cannot see in the documentation. Where/how is the chain and certificate data stored and what precautions need to be taken to to ensure it's persistence? What would happen for example if the membersrvc node crashed and was irrecoverable?

@passkit - I'll give the shortest version of the answer for now (as we continue with the v1.0 release additional operational documentation will be added as we implement the v1.0 architecture / design). I'm not going to answer in the context of v0.6 as that version is based on a prior architecture and we are adding any new capabilities there nor will running that version in production actually be supported moving forward.
Here's the v1.0 "highlights"
*chain data*
each *endorsing/committing peer* basically "stores" the following:
1. *file-based ledger* - we store the _blocks_ (each block contains transactions which create/update _keys_ in the system) using a file-based structure persisted on each peer's local file system. You can of course "back" this file up but there is also the ability for a peer to "recover" the ledger by communicating with other peers and/or ordering nodes to retrieve the entire ledger as well
2. *state store* - the state store holds the latest _value_ for each _key_ . The default state store is LevelDB (goLevelDB to be precise). We are also working on an optional CouchDB-based state store as well. Of course you can back this up as well, but think of the state store as more of a cache which can be rebuilt from the file-based ledger
3. *identity* - cryptographic material used by each peer to identify itself (typically be signing messages which flow through the system). The default provider is X509-based so you would typically need to minimally backup the private key (or store it in an HSM). You would also back up the X509 public key although technically you could generate a new certificate request using the private key
*ordering nodes*
The default ordering service for v1.0 is crash fault tolerant and based on Kafka so we can leverage best practices for deploying a CFT cluster of Kafka nodes. Additionally, there are _shim_ nodes which provide the external interface(s) for the ordering service and each of them maintains a file-based ledger of "blocks" as well. This is basically the same thing as the file-based ledger above for the peers
*certificate data*
in the v1.0 architecture, we have removed the "dependency" between peer nodes and fabric-cop (which takes the place of membersrvcs). fabric-cop supports fault tolerant deployments (e.g. multiple nodes) but again you'd need to minimally back up things like the certificate signing pair, revocation lists and if you use transaction certificates there are certain pieces of info which need to be backed up. The good news is that the storage for this info is actually a database (e.g. MySQL, Postgres) so you would simply follow standard procedures there.
There is also a bunch of crypto material which is actually distributed via the blockchain itself to all of the peer nodes (e.g. channel membership, trusted toot authorities, etc) so all of that information persisted to the chains themselves
More to come, but hopefully this gives you the basic idea

@garisingh Thanks so much for taking the time to explain. I have tried to build the latest V1 images, but I’m having some trouble and multiple tests are failing. Are there any pre-built docker images like with the v0.6?
garisingh
2016-12-29 10:57
@passkit - unfortunately that is a work in progress - hopefully we'll start publishing soon. There's a lot of active development and many changes going on prior to the holiday so timing was not quite right in terms of publishing images. But it should be much easier to build images. BTW - can we move this chat over to the #fabric and/or #fabric-dev channel since this is a general channel for all of Hyperledger?

@umasuthan yes I have "hyperledger/fabric" & "chaincode_example02" folders are in the same folder path. But after pulling "fabric" from gerrit I am unable to run "go build" and also there is no "build" folder inside fabric by default.
umasuthan
2016-12-29 12:15
I don’t think you will see a build folder inside fabric folder. The errors you posted are because of the package resolution failures. Did you make any changes to the example code?
mpravatranjan
2016-12-29 12:47
@umasuthan
I just deleted fabric and chaincode_example02 and pulled those two again.

@umasuthan not sure which version of the fabric you are running. However, in either case 0.6 or 1.0, I was able to build the example02.go that comes by default. In the version you have curled, you have some issues ...stub.GetFunctionAndParameters undefined (type shim.ChaincodeStubInterface has no field or method GetFunctionAndParameters)
mohanv

@umasuthan .. can you try and build the default example02 under the #fabric/examples directory
ratnakar
2016-12-29 19:34
@mpravatranjan, Not really sure why you had to delete the whole fabric folder. To build chaincode_example02 you would need all the depndent libs which are available in fabric.
Instead of building the chaincode from this folder `$GOPATH/src/github.com/chaincode_example02`, can you try building from this folder `$GOPATH/src/github.com/fabric/examples/chaincode/go/chaincode_example02`

Hell everyone:
I start 4 vp for a test enviroment for hyperledger/fabric and deploy one chaincode.
I called randdom function in the invoke function to produce a random number in the chaincode.The code is as following:
I tried to run them in the 4 VP test enviroment. I found the random result is different on each of VP, but the 4 vp test enviroment did not report any error and let chaincode run
My quesiton is:
1. Why consencus In hyperledger can reach agreement to let chaincode to run successfully although the chaincode the random value is different on different VP?
2. What is concrete transanction process?
Who can help to answer it?
Thanks

Thus, failing to delpoy the chaincode and getting back a chaincode ID. I created a service a few days ago trying to do the same thing and it worked instantly. Have other's experienced similar issues when deploying to Bluemix IBM Blockchain?

v1.0 compiled peer binary doesn't have network login command, how should fabric peer authentication be performed/protocoled?
Can REST approach can still be used to launch the chaincode as shown in documentation for chaincode example02?

I'm new to chaincode, I find setup of the hyperledger a non consistent process. I repeat the steps of registering the chaincode with peer (the code is ready & built) but CORE_CHAINCODE_ID_NAME=mycc is not recognized... I assume I'm executing this command within the code directory, which is within the gopath/src folder?!

So it was successful once. After a PC restart hours later (docker-compose up once more), I have REST interface, but I can not rerun the CORE_chaincode_ID_NAME AGAIN. So its already linked. So I would have to take every thing down first?!

@abhishekseth - if you are using the NodeSDK for v0.6, the content of the Dockerfile used for chaincode images is actually hard-coded: https://github.com/hyperledger/fabric/blob/v0.6/sdk/node/src/hfc.ts#L1759
I believe the same holds true for the Java SDK as well
If you are still using the REST API, the base content for Dockerfile content is defined in `core.yaml` here: https://github.com/hyperledger/fabric/blob/v0.6/peer/core.yaml#L272 and then chaincode specific info is added in the peer code - for example for Go-based chaincode see here: https://github.com/hyperledger/fabric/blob/v0.6/core/chaincode/platforms/golang/package.go#L62
Note: Golang chaincode does not actually use `go get` - it uses `go install` . The only place where `go get` is used is prior to creating the chaincode container when you deploy chaincode via the REST API using the "path" parameter and include "http/https" in the path: https://github.com/hyperledger/fabric/blob/v0.6/core/chaincode/platforms/golang/hash.go#L118

Please note that at around 15:06 the screenshot showed that the resulting block from “step2” has [0] transactions, meaning the failure from VSCC is actually valid (despite what I said in the video). This is due to a bug that will be fixed by @yuki.k in https://gerrit.hyperledger.org/r/#/c/3569

I have been practicing the chain code registration methods, first, (1/4 peer) examples then from hyperledger fabric example. So for development purposes for running my own code (chain-code operations within "init") what is the most effective method in environment setup. Should I setup with a admin-user, to all retesting as needed? Is Windows able to fully run the Hyperledger server correctly?

abhishekseth
2017-01-04 05:15
@garisingh, okay.. Let me tell u my problem actually. Assume I am using REST API to deploy chaincode. I want to give the private git repo path as chaincodepath. But I am getting errors in that. Can you tell me how do I achieve that?
humblealex
2017-01-04 05:27
@forestjqg Yes, I have encountered the same issue. I guess you are running v0.6. In v0.6, the chaincode is ran after the consensus has reached agreement, which means the consensus part does not check what result of the chaincode being executed. That is why the random number can be put into the worldstate. It has been indicated that in v1.0, this problem will be solved, for the chaincode reslult will be attained first, and then goes to consensus.
vinshu
2017-01-04 05:38
@abhishekseth Are you deploying in prod or dev? If you are using dev mode you need to deploy the chaincode with inline command :-

@spiro Same as I told Abhishek, Also you need to expose the REST listening port to a host port for calling outside the docker(from say a browser)

Hello! I have a question about the consensus algorithm in Hyperledger Fabric! http://hyperledger-fabric.readthedocs.io/en/latest/FAQ/consensus_FAQ/
The link mentions that there are three choices, but lists only really one choice (excluding the no-op, why would you have no-op?)
How does Batch Practical Byzantine Fault Tolerance algorithm handle untrusted miners/validators? I'm under the impression that it can only be used for centrally managed blockchain systems. What prevents an arbitrary system from adding lots of blocks to the chain, causing a denial of service?
The documentation does not mention any schedules either. Is it the case that Hyperledger Fabric is only applicable for blockchain applications without distributed management / distributed cryptocurrencies?
Am I correct in assuming that the Hyperledger Fabric is meant for "consortium blockchains" which require the users to trust the provider of the blockchain and to suffer potential infrastructure risks if the provider goes out of business for example?

hey everyone. im currently inspecting the communication of browser to chaincode via hfc sdk. is there any tutorial on this? i couldnt find a simple example how you effectively can communicate to a peer for an invoke or a query using hfc sdk
conroydave
2017-01-04 11:07
i figured it out
conroydave
2017-01-04 11:07
it was because i had master/tree in the url
conroydave
2017-01-04 11:07
which while valid in browser, not for curl
saikondaveeti
2017-01-04 11:11
Hi!!
I am trying to run the marbles examples locally.. I have setup network.. Deployed the chain code and I get the 'websocket up' message.. Now I should be able to access localhost:3000, but couldn't.. Is it because that local host refers to the Docker-compose container?
conroydave
2017-01-04 11:11
what os are you running
conroydave
2017-01-04 11:11
i find it is always safer to use the IP address of the docker container
saikondaveeti
2017-01-04 11:21
@conroydave : thanks when I gave the IP of the node through which it was deployed instead of localhost it works as expected
benlewis
2017-01-04 11:23
Should the peer cli echo transaction responses, e.g a return from a query or invoke statement?
conroydave
2017-01-04 11:23
cool
benlewis
2017-01-04 11:24
@thojest there are some node sdk examples in the git repository. There's also the IBM car lease demo which may be helpful https://github.com/IBM-Blockchain/car-lease-demo

i have used ethereum quite a lot over the past year for a number of PoC’s and have written smart contracts on solidity. I know hyperledger is more oriented towards an enterprise level permissioned private networks. But wanted to know if anybody with experience on using both, how does the development capability match up?
conroydave
2017-01-04 11:36
i have spent a few weeks looking at both
serinth
2017-01-04 11:36
Not sure if i would put anything on Bluemix. I'm more inclined to use AWS.
conroydave
2017-01-04 11:36
i felt ethereum was a bit ahead
conroydave
2017-01-04 11:37
that being said, i was able to get hyper ledger chain code running locally and in the cloud in a few hours tonight
praveennagpal
2017-01-04 11:37
yeah..thats what i feel as well but i have only started looking at hyperledger..so my assessment may not be correct
praveennagpal
2017-01-04 11:37
ok
praveennagpal
2017-01-04 11:37
dud you write chaincode in golang?
praveennagpal
2017-01-04 11:37
*did
conroydave
2017-01-04 11:37
yeah, adapted their tutorials
praveennagpal
2017-01-04 11:37
ok
conroydave
2017-01-04 11:37
no prior experience
serinth
2017-01-04 11:37
wouldn't ethereum contracts be more restrictive? They have their own contract programming language right. Whereas you could just use Go with this.
conroydave
2017-01-04 11:38
i feel like the language is one of the smaller hurdles in the bigger picture
serinth
2017-01-04 11:38
plus you'd have to mine for ether which is a global resource?
praveennagpal
2017-01-04 11:39
yes..thats true..there is nothing like gas in hyperledger
conroydave
2017-01-04 11:39
and instead you pay your web hosts
serinth
2017-01-04 11:39
so if your business depended on ether you'd have to find a way to get a lot of gas.
praveennagpal
2017-01-04 11:39
but i found web3 libraries quite useful for transacting with smart contracts from our dapps
conroydave
2017-01-04 11:39
the gas actually promotes efficient code and resource usage
praveennagpal
2017-01-04 11:39
i know there is hfc node js client sdk
benlewis
2017-01-04 11:39
Isn't the ideology behind fabric vs ethereum different too? Gas is needed because Ethereum is public
praveennagpal
2017-01-04 11:40
yes
serinth
2017-01-04 11:40
yeah, though i do know Jetstar is using ethereum for managing their flight bookings with travel agencies
praveennagpal
2017-01-04 11:40
that is one of the reasons..it the economic fuel for proof of work in ethereum
conroydave
2017-01-04 11:40
i just feel that if you are going to blockchain for your business need it is because you are trying to get away from centralized services
conroydave
2017-01-04 11:41
yes they are both open source but the implementation costs are not negligible
praveennagpal
2017-01-04 11:42
architecturally..i like the concepts in hyperledger for a private network blockchain but i think the fabric dev tooling is still in its infancy compared to ethereum
conroydave
2017-01-04 11:43
depends on your needs for privacy
conroydave
2017-01-04 11:43
you can control who has access to smart contracts
serinth
2017-01-04 11:43
i'm still trying to figure out a use case for it and how to justify it
conroydave
2017-01-04 11:43
you can black list, freeze assets
conroydave
2017-01-04 11:43

praveennagpal
2017-01-04 11:43
yes
conroydave
2017-01-04 11:44
the rest api is nice tho
conroydave
2017-01-04 11:44
cause i got a few poc’s working in ethereum and im not sure how to take the next step with hookin up to webservices
praveennagpal
2017-01-04 11:44
thats true,..excepts in stratos blockapps.. you don’t get the rest api in core ethereum
conroydave
2017-01-04 11:44
i probably need to just look into it more, but rest out of the box is great
conroydave
2017-01-04 11:45
with rest i was talkin bout hyper

@benlewis from my point of view hyperledger and ethereum are different in that hyperledger aims at providing business solutions based on a private chain and ethereum offers a public permissionless blockchain for smart contracts
thojest
2017-01-04 12:04
however you can also run your private ethereum blockchain
benlewis
2017-01-04 12:10
Proof-of-work seems like it's redundant in a private network though. I've seen Credits speak before at an open data conference, and they highlighted the fact that you already have a degree of trust between businesses, but blockchain can minimise that, but not eliminate it whilst giving the other benefits in terms of auditability, and resilience
thojest
2017-01-04 12:23
so am i basically right that you use nodejs to build a website and then include the hfc sdk to communicate to the peers for invoking commands on the blockchain ?
benlewis

@thojest as far as I understand it, yes

using v1.0 architecture, I am having problem to deploy a custom 'learn-chaincode' using CLI
Step followed"
1. Run peer node (used the connenct-a-thon peer image) in the DEV ('peer node start --peer-chaincodedev').

Hi everybody! I`m modifying the chaincode_example02 aswell as his helloblockchain.js , but i`m running into a problem. I`m modifying the chaincode but nothing happens :disappointed: I even reduced my init to:
if len(args) != 1 { return nil, errors.New("Incorrect number of arguments. Expecting 1") }
and i`m passing 4 parameters and error is not getting triggered :confused: so i don`t know what can be happening

@shsedghi I've seen this where v0.6 code and v1.0 code are getting tangled together.. That is, where people have used the v0.6 code and while following the documentation, they are then getting code from the master branch which is v1.0 code. This happens because at the time the v0.6 documentation was written, the master branch was v0.6 code. But now, the master branch is pointing to v1.0 code. E.g. in this section of v0.6 documentation http://hyperledger-fabric.readthedocs.io/en/v0.6/Setup/Chaincode-setup/#running-the-chaincode there is a curl command to get the chaincode and a git command to clone the fabric code.... these will currently pull from the master (v1.0) branch....e.g. if you've downloaded v0.6 docker images and are following that section or doing something similar, it can cause symptoms similar to what you are seeing.
*Note:* this may or may not be what you're running into- I've never used the Java SDK and you don't mention your exact environment and which code you're using, but it's at least something to investigate

@chainsaw Even though CN is http://n.ssl.fastly.net .... in Certificate Subject Alternative Name there is entry for DNS Name: http://www.hyperledger.org .... So certificate is valid and https should work fine

Hi, I'm trying v0.6 and having question about NVP node. Does NVP node maintain the ledger? It seems I cannot query any transactions or see increasing blocks on NVP node.

Hi, I already posted that issue in the #dockerimages channel but maybe somebody else here has an idea about it - it happens when I want to deploy chaincode on a hyperledger 1.0.0-prevew peer - not sure if the docker container it should be looking for is the x86_64-0.6.1-preview which is the only one available on dockerhub right now
'''- 017-01-04 14:10:29.838 UTC [dockercontroller] deployImage -> ERRO 464 Error building images: Tag x86_64-1.0.0-preview not found in repository http://docker.io/hyperledger/fabric-ccenv

general n00b question: using blockchains like ethereum or hyperledger. am i correct that most part happens off-chain like running smart contracts and most internal variables. so to say only important results which need the security aspect of the blockchain are then stored on-chain ?
thojest
2017-01-05 12:45
well i think in ethereum the smart contract code is stored on the blockchain isnt it?
thojest
2017-01-05 12:49
what my question is aiming at, im trying to get an overall picture of the architecture. and the question which always comes to my mind is whats happening on the blockchain and what is off-chain
thojest
2017-01-05 12:50
for example the go-chaincode is afaik running in a docker container. so that would be off-chain and via the shim interface it is writing sensitive information into a new block of the blockchain
thojest

@thojest the container containing the smartcontract is running on the peer
bfuentes
2017-01-05 13:40
the hash of it has been recorded on a block
bfuentes
2017-01-05 13:40
so what do you call “on-chain” ? the blocks , the world State or the peer itself ?

@bfuentes with on-chain i mean the data which are written into a block of the blockchain
thojest
2017-01-05 14:52
could you please elaborate on world-state. what is it?
thojest
2017-01-05 14:52
so you mean the docker container is running on the peer???
bfuentes
2017-01-05 15:24
@thojest I think you should read the documentation. Yes the docker container is running on each peer. The worlState is the stateful part of the blockchain. Blocks are stateless and purely declarative. Having a block does not mean the smart contract has change anything on the world state (error, no valid, etc ....)

general question: am referring the auction use case ( bcoz am planning to implement similar usecase on fabric ), in auction use case the items are moving from one person to other person when we query its shows only the current worldstate of the chain so question is 1) if i want to see complete audit trail for a item how can i query in fabric 2) when a record get stored in block it will have hash for that block, so when show the complete audit trail for a item i believe i should show the records with corresponding block hash, is my understanding is correct? 3) is it possible to get complete audit trail for an item by query block chain any time or do i need to store transaction in external db's by getting hash from block chain when write into blockchain 4) for same use case is it possible to store the image in block chain ( consider my image size will be more than 20MB ) and get a hash for it and refer same hash in actual transaction
comments appreciated very much :slightly_smiling_face:

Hi!! I have set up four peer network locally as decribed in "https://github.com/IBM-Blockchain/fabric-images" and tried the marbles and asset management examples. I am currently trying to run the asset management02 application described in "https://github.com/hyperledger/fabric/tree/master/examples/chaincode/go/asset_management02". I have replaced localhost with membersrvc and 0.0.0.0 with vp0 in asset.yml file and tried 'go test'. I get the following error :

@saikondaveeti i recently also had this token does not match error
thojest
2017-01-06 12:07
however i was trying something different
thojest
2017-01-06 12:07
in my case it helped to delete the content of the production folder
thojest
2017-01-06 12:08
`rm -rf /var/hyperledger/production/`
thojest
2017-01-06 12:08
warning! this recursively deletes all the content in that folder
thojest
2017-01-06 12:09
but if i understood correctly somewhere in this folder data for the enrollment is stored and it has to be cleaned because you cannot enroll twice.
thojest
2017-01-06 12:10
however it would be good to hear another opinion on that because im no expert and just got started, too

2017-01-06 18:45
@praveennagpal : Users can be added in your membersrvc.yaml file. I believe that node.js has a programatic way to add users, as well. You cannot add users with the REST API (at least that I found).

@hi.rose If your fabric code is not running in Docker containers, clear the contents of */var/hyperledger* before you run the *cp-web* nodeJS app. Similarly, if the cp-web app itself is not being run in a Docker container, clear the contents of the *keyValStore* directory within your *cp-web* directory. This is the first thing I'd try, and if this works, do this each time before you run the demo. If this doesn't work, I recommend you ask further questions in the #fabric channel
hl.rose

2017-01-07 15:34
@hi.rose okay, in this case.... try clearing out your *keyValStore* directory before each run of the app, and using a new Docker container each time is a good strategy to use. This assumes that your new Docker container will start with a empty or non-existent /var/hyperledger.

Hello @bercinho IBM does offer some support options, that can vary depending on your topology, e.g. whether you are running on IBM's Bluemix or whether on-premises, which hardware platform (e.g. intel x86, power, or z Systems), etc. If you know a bit about your desired topology let me know here or in private message, and I'll try to get you pointed in the right direction.

@gaurav You need config below volume setting in your docker-compose file: ` volumes:

Thanks @bain, the volume settings seem to have resolved the docker endpoint issue. However, now I am getting this error: vp0_1 | 07:35:39.674 [dockercontroller] deployImage -> ERRO 01d Error building images: Tag latest not found in repository http://docker.io/hyperledger/fabric-baseimage

this image is chaincode runtime docker image. there is no latest tag for this image. so you need download right tag for your machine, x86, or others.
bain

Hyperledger is an Open Source project. IBM is giving support if you use the Blockchain Bluemix service running Hyperledger (infrastructure), gives training sessions, can help developing a PoC via IBM Blockchain&Bluemix garages over the World. Some IBMers are part of Ecosystem & Developers and give workshops or conference at different events (Meetups,Devoxx,InterConnect,etc...)

I have a question for chaincode deploy on hyplerledger
When deploy a chaincode on hyperledger with 4 VP
The chaincode should be deployed on each vp of the 4 vps.
But I checked the code for deploy, only find the chaincode is deployed on one VP.
Who know how the chaincode is deployed on other VPs?Where can I find the related code for deploy chaincode on other vp in hyperledger/fabric project?
Thanks

basically if chaincode is not propagated to other nodes it may mean there is an issue with connectivity between nodes/VPs

Hello all:
I have a question for hyperledger fabric
I wrote a chaincode which will generate random in invoke function and put the random to ledger with putstate.
In a 4 vp environment, if I invoke this chaincode to generate random, this operation will lead the state on each vp is different.
According to the concensus theory, this operation should NOT be executed in the 4 VP enviroment .
I tested it, but hyperledger fabric executed the chaincode successfully even though the random number is different on each vp.
Who can tell me why this can happen?
Thanks

Hi, are all transactions performed or executed from hyperledger will all transmitted to bitcore "MainNet" network or bitcore mainnet has nothing to do with it? Pardon for my newbie question. I'm literally new to blockchain technology more so to hyperledger.
pd93
2017-01-12 11:05
@marvsperez Welcome to the community. Just to clear things up.. Hyperledger has nothing to do with Bitcoin/Bitcore. It is completely unrelated except for the fact that they are both blockchains. Bitcoin is a single, public blockchain that is maintained by everyone who contributes to it. Hyperledger Fabric is a permissioned blockchain. This means that each Hyperledger Fabric blockchain can only be viewed by members who have permission. Each instance of a Hyperledger Fabric blockchain is independent from any other instance. They can each be configured in their own way and they do not interact with one another or any other blockchains (unless told to do so).

@pd93 Thank you for answering. It's my third day of reading about bitcoin/bitcore stuff so I guess I can leave it behind now and dedicated my time exploring on Hyperledger. I'm currently setting up the start-up kit to get a feel of the fabric chaincode.
marvsperez
2017-01-12 11:16
So does that mean I can setup the hyperledger in our own infrastructure?
pd93
2017-01-12 11:17
Absolutely. I run my development environment on a private Debian server. You can host it wherever you like
pd93
2017-01-12 11:18
I should probably also point out that Bitcoin is purely a cryptocurrency whereas Fabric is a much more general purpose. It can be used for anything from financial trading to supply chain management. The possibilities are quite endless.
IBM also have a nice guide for their Bluemix service (which uses Hyperledger Fabric) http://www.ibm.com/developerworks/cloud/library/cl-ibm-blockchain-101-quick-start-guide-for-developers-bluemix-trs/index.html
marvsperez
2017-01-12 11:20
Awesome! It would be a fun to learn and explore. We're working on a new insurance/investment platform and we plan to use Microsoft Azure Service Fabric to build the system in microservices. However, we're heavily exploring to use blockchain if applicable. Lot's of thing to research on.
pd93
2017-01-12 11:22
Best of luck to you! Hyperledger-Fabric is definitely the place to be :wink:
marvsperez
2017-01-12 11:26
Looking forward to it.. but azure service fabric is definitely different from hyperledger fabric.. I could host the hyperledger in docker and deploy in azure service fabric. I just need to know what business logic in our microservice we could use blockchain. :thinking_face:
marvsperez
2017-01-12 11:27
Once I understand this hyperledger/blockchain works, I could see how I can use this in our project.
pd93
2017-01-12 11:31
I'm not familiar with Azure's Service Fabric, so I'm probably not much help. Hyperledger can definitely be hosted with Azure though

@locusf IBM's Bluemix platform is based on Hyperledger Fabric (v0.6) so everything you can do on Bluemix, can be done outside of Bluemix too.

What is the recommended hardware for running Hyperledger docker images (v0.6) on Mac and Windows. I understand the answer could depend on the use case. Lets says, we are talking about development environment. What is the recommended configuration for Mac. I have checked system requirements for Docker, it says you will need Mac Book Pro newer than 2010 and minimum 4GB. We also know that you cannot Macbook pro with 4GB and most Macbook pro systems purchased have more than 8GB or 16GB.

Have you deployed the chaincode, @alacambra? Before you can call the invoke or query, you need to deploy the chaincode. I have also noticed that invoke will return success even if the chaincode has not been deployed.

@alacambra - the deploy call is basically asynchronous so as long as it is properly formatted it will be accepted. Reading above, it looks like you are running in dev mode. Did you actually compile and start your "mycc" chaincode?

I'm relatively new to Hyperledger and going through the tutorials, but ran into a question. I see that there is a certificate in the block when running the rest command. Is this a normal x509 certificate or something else? I ask because I was trying to copy and bracket it with the normal -----BEGIN CERTIFICATE-----/-----END CERTIFICATE-----, but was getting a "Expecting: TRUSTED CERTIFICATE" using openssl

@ingcr3at1on: thanks. The hr onboarding is just the first test to have hands on experience with hyperledger. I agreed with you blockchain may not be necessary for everything. The traditional way may work better in many cases. My actual motivation is to find a proper platform for smart contract for enterprise solutions. Feel free to share with me your experiences.

I am seeing this issue as well though it seems to mostly happen when I run in the cloud. I don't seem to get this when I am running locally.

Hi, does fabric support concurrent read/write handling?

Hi everyone, as most of you probably know, COP is v1's replacement for membership services in v0.6.

Dear All, does anyone know why I may not have Internet connectivity within my Docker Containers? (Note that with "nc" I am able to send text from the Container to the Host, but for some reason I can´t access anything via Port 80)
keithsmith
2017-01-17 14:38
Hi everyone, as most of you probably know, COP is v1's replacement for membership services in v0.6. There have been numerous concerns voiced about use of the name "COP", reasons including:
* lack of clarity on what it really is, so constant explanations required;
* negative connotation in some cultures.
So we are looking to rename the repo, images, slack channel, and executable to "fabric-ca".
The current COP is a CA (Certificate Authority), so the name "fabric-ca" will be meaningful.
Comments are welcome.

2017-01-17 14:45
@bercinho check your docker-compose.yml file to make sure ports are mapped externally for the hosts
kdj
2017-01-17 14:45
eg.
vp0:
image: hyperledger/fabric-peer
ports:
- "7050:7050"
- "7051:7051"
- "7052:7052"
bercinho
2017-01-17 14:52
Hi KDJ
bercinho
2017-01-17 14:52
it´s about port 80
bercinho
2017-01-17 14:52
outbound
bercinho
2017-01-17 14:52
I don´t want to promote any port to the host
bercinho
2017-01-17 14:52
well actually I do the above ones
kdj
2017-01-17 14:52
same thing works for port 80, just specify it for the host
kdj
2017-01-17 14:52
also check your firewall
bercinho
2017-01-17 14:53
its´not a firewall issue, from the host I can run "curl http://google.com" it works
bercinho
2017-01-17 14:53
from the container it will not
bercinho
2017-01-17 14:54
I do have the port mapping " ports:
- "7050:7050"
- "7051:7051"
- "7053:7053"" in the config "docker-compose-nodes.yaml"
kdj
2017-01-17 14:55
so if you want to open up port 80, you have to do the same thing for it as you are above for those ports
bercinho
2017-01-17 14:55
I should not have 80:80 there, it´s the container going outbound to port 80
kdj
2017-01-17 14:55
oh
bercinho
2017-01-17 14:56
it´s outbound communication from the container
bercinho
2017-01-17 14:56
oh and the docker engines are in a overlay network, because I have a multi host setup
bercinho
2017-01-17 14:57
the "docker_gwbridge" is created automatically and seems to work for everything but port 80
o.o

2017-01-17 15:04
so there is a firewall on the host, and what I do is having a transparent proxy (redsocks) running on Port 12345, and having rules in the IPTABLES to route traffic from Port80 to Port 12345 (tcp dpt:80 redir ports 12345), where the transparent proxy will take care of routing it to the webproxy (http://webproxy.aws.db.de)
bercinho
2017-01-17 15:06
for some reason the container still tries to communicate directly with whatever webserver I define instead of having the tcp requested routed to the Redsocks transparent proxy

Hi There,
I’m using the HFC sdk and been noticing that there is a difference in the way errors are returned in the chaincode between invoke() and query().
When I return an error like so:
return nil, errors.New("generic error")
the error is propagated properly only when the error came from a function called through query().
However, when called through invoke(), there is no apparent way to detect the error. When I try it from the Blockchain API portal, I simply get a 200 OK response... and through the HFC library it simply times out.
Getting error signals back from the chaincode/smart contract is very important, so what is happening?

Our organization has a private registry for docker images and the public docker hub registry is not accessible.
Hence the images needed for hyperledger network setup and chaincode deployment are available in the private registry as below:
1. hyperledger/fabric-peer:x86_64-0.6.0-preview -> <REGISTRY_URL>/fabric-peer:x86_64-0.6.0-preview
2. hyperledger/fabric-baseimage:x86_64-0.2.0 -> <REGISTRY_URL>/fabric-baseimage:latest
What is working:
Fabric peer setup through "peer node start" is OK, as we can specify the full path of the image as:
docker run --name peer -e CORE_VM_ENDPOINT=<DOCKER_HOST> -e CORE_PEER_ID=vp0 -e CORE_PEER_ADDRESSAUTODETECT=true -p 7050:7050 <REGISTRY_URL>/fabric-peer:x86_64-0.6.0-preview peer node start
What is not working:
However, when a chaincode is being deployed it needs the image "hyperledger/fabric-baseimage:latest" in the repository to be able to launch the chaincode container.
Any idea, if we can fix this, that is how we may specify the specific docker image for chaincode during deploy of chaincode?

Hi, My hyperledger works perfectly fine in NOOPS with 4 peers. Wanted to confirm. When I make any changes via ROOT NODE it is replicated to all peers and I can see messages or data posted in all the individual ledgers. But when I post any data via peer it only happens between peer and root node and no other peers are updated. Is this correct behaviour ?

However, when I deploy a chaincode, only four nodes has the copy of the chaincode, so I think that the fifth node does not see the others nodes. Could anyone to help me? Thx

And is there a possibility of transaction rollback due to consensus failure or due to a blockchain fork?

@sushilsingh94 : Make sure that the port of your first peer node is available. I have used the following command to forward data coming in on port 7050 of my local machine to the docker image of my first peer node:
```
sudo iptables -t nat -A DOCKER -p tcp --dport 7050 -j DNAT --to-destination 172.17.0.3:7050
```
tkuhrt
2017-01-18 17:59
As another option, you could just use the ports in your docker-compose YAML file:
```
vp0:
image: hyperledger/fabric-peer
ports:
- "7050:7050"
- "7051:7051"
- "7053:7053"

How would you guys compare HyperLedger/Fabric to Ethereum and other open protocols?
falseprophet
2017-01-18 21:18
I see HL as a way that a company or a group of companies can create a blockchain for private/consortium use cases. Perhaps formalizing existing business logic/relationships in a closed blockchain system with a handful of participants who are somewhat trusted (ie have been allowed into the blockchain). It seems like HL/Fabric is still at the planning stage where the kinks are bing worked out
falseprophet
2017-01-18 21:25
I see Ethereum, and Bitcoin to a much lesser extent, as the radical public alternative, where there is one main public chain that powers smart contracts and tokens. There are entrepreneurs launching new products and sudo-companies that raise money by selling tokens (ICOs) that are pushing the tech, use cases and financial market boundaries. Meanwhile, you can also fork Ethereum to create your own private/consortium/enterprise blockchain (with potential changes to the blockchain to enhance security/speed etc - examples include companies like blockapps and multichain)

lets use that as a framework for thinking.
down-the-fall-line
2017-01-19 00:04
A lot of the various "coin-tech" (at least thats what i call them in as much as their core tech derives more or less directly from the blockchain project) groups/companies/etc all position themselves as doing things in a totally disruptive way. The coin-tech companies believe that their line of thinking will totally disrupt existing value chains and economies. In the edge cases, there's a vibe of anarchy. Conversely, the HyperLedger is positioned as a sustaining technology, to take existing value chains to the next level of efficiency (and there's a number of ways to define that). This is not good vs bad, but two very different ways of thinking about how to bring the tech to the market and achieve adoption.
down-the-fall-line
2017-01-19 00:06
Tending toward the disruptive side, I see some very clear advantages in healthcare (my current focus area). There's a lot of inertia to overcome, but thinking in christensen-like ways, a small team with the right resources can crack that.
falseprophet
2017-01-19 00:24
I agree that Hyperledger is s way through which corporations can adoption blockchain technologies as a sustaining innovation versus disruptive.
Christensen has a very specific definition of what is disruptive vs sustaining:
He defines disruptive innovation as:
“An innovation that is disruptive allows a whole new population of consumers at the bottom of a market access to a product or service that was historically only accessible to consumers with a lot of money or a lot of skill.”
And sustaining innovation as:
“making good products better in the eyes of an incumbent’s existing customers”
When you look at the events and projects unfolding in the public blockchain space, they confirm to what Christension would define as disruptive.
ICOs: new and cheaper way of raising money ie. don't need to go through the VC song and dance or pay the financial industry to IPO.
Ethereum based projects like Augur, Gnosis, ICONOMI, Melon Port: Alternative financial services targeted at a new niche market of traders, speculators, investors within the crypto-market.
Bitcoin - a new asset class that lives outside the traditional financial industry where trading is facilitated by niche crypto-exchanges with lower trading fees than traditional exchanges and capital markets.
So, to conclude, we have a technology (BTC & ETH) that is able to provide cheaper and more accessible financial services to a small but growing early-adopter market (perhaps growing too slowly... there may be ~5M people who own BTC and maybe 200,000-500,000 that really care a lot about blockchain).
If you ask me, Hyperledger does not prepare corporations against a being disrupted by the Ethereum and Bitcoin ecosystem.
Hyperledger aims to reduce costs and improve existing products. Nothing wrong with that, but provides no hedge against being disrupted by an emerging crypto-market.

@falseprophet ref your conclusion: i totally agree. Not the point i was trying to make, sorry if it was interpreted that way. I was merely positing that hyperledger itself is being positioned as a sustaining disruption within the corporate ecosystem. In short, HL makes your IT stuff better. It does nothing (if your nike selling lace up shoes) to prevent you from being disrupted by Marty McFly self tying shoes :slightly_smiling_face:. In my experience, countering disruption within a corporation's franchise market requires a very different way of corporate thinking and strategic planning--- has everything to do with corporate culture, and little to do with the tech that used. Different topic entirely. The question for this community is how do you make this HL stuff easy to use for the devs that are newbies. Think about the early days of amazon web services- a dev could with a few mouse clicks have their own server to play with. No corporate IT process. Heck, maybe not even anything to do with their day job at all. From what i'm seeing, that's the central challenge for the HL community.

falseprophet
2017-01-19 01:05
I just wonder if it gets bogged down by corporate innovation. As you alluded to, disruptive breakthroughs require an innovative corporate culture, but most innovation departments just want to do some HL stuff (with IBM realistically) check off the blockchain box and move on without really doing anything too innovative to hedge against the very real threat that blockchain poses.

question: is there a strategy channel in this team. this is a great topic (IMO), but may be disruptive to some of the other members who are trying to get things to work.

I suppose HL could redefine how biz processes and biz relationships are created/managed - but that requires buy-in from a number of actors or a major obvious internal ROI opportunity (which again would be sustaining). I guess my point is that even if these ideas succeed - it just helps a corporation do what they are already doing. If Ethereum, Augur, Iconomi or a number of other radical ideas suceed (such as decentralized trading, predictions markets, sports betting and P2P payments)... the game has changed.

you got it! IMO, a SWAT style line of thinking will indicate how to best navigate these uncertain, yet end of the day Blue Ocean opportunities.

you may simply need to open a new terminal window

or make sure the `/usr/local/bin` is in your PATH ahead of `/usr/bin`
or in the same terminal window:

which tar
tar --version

have you tried just “make"? It worked for me.
eugenluft
2017-01-19 15:25
same issue
vadim
2017-01-19 15:25
on macOS
vadim
2017-01-19 15:25
do you have rocksdb installed?
vadim
2017-01-19 15:26
also, I think you use macOS, so there chaincode containers cannot really communicate with peer process
vadim
2017-01-19 15:27
so I had to go back to using vagrant
eugenluft
2017-01-19 15:34
ok, but just to make sure: If i run `peer chaincode deploy ......` (after register the chaincode) does peer creates a docker container to run the chaincode?
dknochen

vadim
2017-01-19 15:35
yes it does. However, docker container crashes with a message that it could not talk to the peer process
eugenluft
2017-01-19 15:40
ok. it helps :slightly_smiling_face: And do you know why it´s not possible to stop this process after deployment? , eg CORE_CHAINCODE_ID_NAME=ccID CORE_PEER_ADDRESS=0.0.0.0:7051 ./mychaincode.
vadim
2017-01-19 15:42
not sure I understood correclty, but in dev mode all chaincode invoke/queries are handled by this process
vadim
2017-01-19 15:43
so if you stop it, you can’t invoke it anymore
eugenluft
2017-01-19 15:49
I trying to understand the different between register and deploy and all the running processes. If chaincode deploy -n ccID -c… is creating the docker container with the chaincode, why do i need the running register process?
vadim
2017-01-19 15:50
you need to run a process only in dev mode
vadim
2017-01-19 15:50
at least for v1, I did not work much with v0.6
eugenluft
2017-01-19 16:02
ok … and one more question :slightly_smiling_face: Is it possible to deploy more then one chaincode in one ledger? If yes, does the ledger starts one docker for all chaincodes or for each one docker container?
ikruiper
2017-01-19 16:13
@eugenluft 1. Yes, 2. (for v0.6 anyway) one docker container per chaincode for each of the validating peers (not sure though how that will work in v1 in terms of which type of peer will need to run all the chaincodes, or if a certain chaincode can be run on a subset of peers, etc.)

@eugenluft as per my understanding, the registration of chaincode is required only in dev mode as in the dev mode, it does not spawn a docker container per chaincode..in non-dev mode, only the deploy step should be enough as in that case, the docker container shall be initialised per chain code service

Hey everyone,
I and a friend have started to do our master thesis based on Blockchains potential in customer data management. The motivation behind it was because of the new EU regulation General Data Protection Regulation for 25th may 2018. In the regulation, Organisations outside the EU are subject to this regulation when they collect data concerning any EU citizen.
GDPR is designed to give individuals better control over their personal data held by organisations. Personal data is defined as any information relating to a person who can be identified directly or indirectly. This includes online identifiers, such as IP addresses and cookies, if they are capable of being linked back to the data subject.
Indirect information might include physical, physiological, genetic, mental, economic, cultural or social identities that can be linked back to a specific individual.
A key part of the regulation requires consent to be given by the individual whose data is held. Consent means “any freely given, specific, informed and unambiguous indication of his or her wishes by which the data subject, either by statement or by a clear affirmative action, signifies agreement to personal data relating to them being processed”.
Most of the factors the Blockchain can work well with, however, consumers have the right to access, rectify or erase the data and the right to withdraw consent at any time.
Is there a way to tackle the erasure of data at all?

@omar0117 I am new here, so don't actually know anything:
But what data do you want to erase? Would it be enough to forget the link between the person and their identity in the system; instead of completely removing something on the blockchain?
Then it would be a question regarding how the membeship services/registration authorities work; which someone who understands them might explain.

do someone knows what does "handler not found for chaincode mycc” exactly means?
garisingh
2017-01-20 17:33
@alacambra - when running in "net" mode it means that your chaincode was not properly deployed / started
when running in dev mode, pretty much the same thing - usually happens if you have not launched your chaincode executable

@satyam_agl
Thankyou for responding to my message. Here are the details.
I am following this tutorial : http://hyperledger-fabric.readthedocs.io/en/v0.6/starter/fabric-starter-kit/
what happens after i run "node app"?
I also looked at this tutorial :
http://hyperledger-fabric.readthedocs.io/en/v0.6/Setup/Chaincode-setup/
Even though i was able to do all POST and GET requests, this documentation does not provide a good overview of what exactly is happening?
Here are my questions :
1) What is the difference between ethereum and fabric? I have worked on ethereum a bit and i would like to know what does fabric have that ethereum doesnt?
2) How can i build a DAPP on fabric?
3) How do i mine using fabric? are there any commands that i can run in terminal?

@vi *If* you are using the Fabric v0.6 Docker images, this *could* be your problem: I've seen this where people are trying to use the v0.6 branch of the code and then are following the instructions in the v0.6 branch of the documentation, but....get twisted up because there are a couple spots in this doc where it has a wget (for the chaincode) and a git clone (for getting the fabric code available locally in order to build the chaincode) that refer to *master*. The problem is, that *master* is now v1.0 code. So, they are running Docker images with v0.6 code but when they build the chaincode locally, it incorporates v1.0 code in into it. The solution is, in the *wget* and the *git clone*, change *master* to *v0.6* in the path name. I am being purposely vague as to where this documentation is, because if I've guessed correctly, you know what I'm referring to, but if I've guessed wrong, it's something else and I don't want to lead you on a wild goose chase. I hope this helps.

@miketwenty1 Blockchain is a technology- first popularized with Bitcoin. Hyperledger is a consortium based on enabling blockchain technology for business (my words, go to https://www.hyperledger.org for "offiicial" verbiage). Multiple projects have been submitted to the Hyperledger consortium. Fabric is one of them. Fabric is built on top of blockchain technology. The fundamental difference between, say, Fabric and Bitcoin is that Bitcoin uses an anonymous, permissionless model where consensus on transactions is achieved through Proof of Work, while Fabric is based on a permissioned, authenticated model- users are typically not anonymous and thus consensus for transactions can be achieved more efficiently as compared to Proof of Work.
miketwenty1
2017-01-21 22:10
@silliman so does that mean fabric is using blocks?
silliman
2017-01-21 22:14
@miketwenty1 yes, Fabric has the same concept of blocks that can contain multiple transactions, and blocks are hashed, and linked together such that immutability is achieved- achieved in the sense that if a bad actor were to tamper with a block's contents, the good guys can catch that through verifying the chain

@silliman how are the block size and block times determined?
silliman
2017-01-21 22:18
@miketwenty1 At a high level, block size and frequency are controlled by configuration variables- details differ between v0.6 and v1.0 of Fabric- but for both, you can say that a block is cut when a maximum of *X* transactions are ready to block, or after an elapsed time, even if the max of *X* transactions isn't ready.
miketwenty1
2017-01-21 22:22
arbitrary parameters? I guess what I'm wondering is.. in a normal permission based system using something like a message broker or database I would like transactions to be near instant, what advantages are achieved through grouping data in blocks.
silliman
2017-01-21 22:27
user-configurable, not sure the min and max values, not sure if the elapsed time is in seconds or milliseconds. "Near instant" is in the eye of the beholder, for instance there is a lot of work going on under the covers, a lot of cryptography, and most consensus algorithms require some work- if you're used to millions of transactions a second, e.g., you're just not going to get that at this point with Fabric.....the stated performance goal is 100,000 txns/sec and we're not there yet. It's a different paradigm.

miketwenty1
2017-01-21 22:28
so was doing a little research.. fabric is using couchdb?
silliman
2017-01-21 22:31
@miketwenty1 For v0.6 the chain itself and the state are both in RocksDB. For v1.0 the chain has moved to goLevelDB and that's hard-coded, but the state is pluggable- it defaults also to goLevelDB, but a couchdb implementation is being (or has been, not sure if the coding for it is complete) developed for the state.
miketwenty1
2017-01-21 22:36
@silliman seems like a cool system, but still confused on why the need for blocks.
silliman
2017-01-21 22:39
@miketwenty1 the hashing that provides the links is done at the block level, not at the transaction level, so the immutability that is a salient feature of blockchain needs this concept of blocks.
miketwenty1
2017-01-21 22:43
since no proof of work is being done.. I would imagine no nonce is needed.. no miners.. so the hash link is just using data from the previous block and agreed upon by trusted nodes/actors?
silliman
2017-01-21 22:50
@miketwenty1 no miners are needed....you're getting into the implementation details and pushing up against the boundaries of my current level of knowledge, I think nonces may still be used in places to help prevent replay attacks and stuff like that... each block contains a hash of the previous block... the agreement among multiple nodes is done by consensus. In v0.6 there is "noop" which is essentially for testing purposes with a single node, and then there is PBFT (Practical Byzantine Fault Tolerance) which requires a minimum of 4 nodes to work right, because the algorithm says you need *3f + 1* nodes if you are willing to tolerate *f* bad actors. I think in v1.0 the consensus algorithms are 'Solo' which is similar to noop in that it's really just meant for 1 node and testing purposes, and then a consensus called Kafka has been implemented. A variant of PBFT called SBFT (for Simplified Practical Byzantine Fault Tolerance) is under development for Fabric v1.0 but I think that one may not be fully baked when v1.0 is first released. If you need more details #fabric-consensus-dev is a good channel to drill down deeper, maybe #fabric-crypto for questions on nonces. If you're ever unsure where to ask start at #fabric and if someone thinks you should ask elsewhere, they'll point you in the right direction.

@gvlax - I believe marbles v3 is targeted at the Fabric v1.0 release (the stuff in master that is in progress). We have not put out any Docker images of the current master / V1 stuff yet but should have those out at the end of the month. The fabric V1.0 architecture is very different from V0.6 and earlier and therefore the APIs implemented by hfc are very different

@wellenreiter have a look at this example: https://github.com/ratnakar-asara/hello-blockchain , the chaincode is in `src/chaincode` directory where there is also `vendor` thing ... If you want to run the example, you have to have docker-compose at least 1.9.x installed.

@wellenreiter did you first try put your chaincode (.go) to the _hello-blockchain_ `src/chaincode` directory? Remember to remove the existing `example02_with_events.go`. Just clone the project to your location.
wellenreiter
2017-01-22 21:17

gvlax
2017-01-22 21:21
@wellenreiter actually it may be a good sign. The deploy operation tried to call `init` method in your contract. If your contract is not prepared for it, it is it does not have such a method, the deployment process could just fail .
You can always watch peer logs running this command `docker logs -f vp0`

You can communicate using ProtocolBuffers, they are very cheap in memory and cpu, will work in almost any micro that can run C/C++
gatakka

so in general, you have to make a socket connection to one of the Hyperledger nodes, and send/get data using proto buffers

I know but we have a hypothetic situation, where We need to prove it in a court

then you can find the code in the repo which does that and use it to build your own tool which will check the chain validity
ruslan
2017-01-23 15:28
I think as well, although I’ve found some useful functions in core/chaincode/querier.go for my purposes, but I’d thought that fabric has some tools
vadim
2017-01-23 15:29
well as long as you trust your peer process implementation, you don’t really need such tools

@dolanor in general idea is the same. Etherium create there own "custom" binary protocol. Hyperledger decided to use well tested, proven scheme for efficient binary encoding, that has ports in every proper language - Protocol buffers. About the nodes there is no difference in which node you are connecting. Hyperledger will take care for all communication between nodes and there roles. Of course, you have to connect to node that has proper role for executing "commands". So, you expose one or many nodes to public access, you can assign DNS A record to node IP address if you want, and connect using this domain/IP address. And for sure you can create some "internal" network so that only IoT devices can connect to this node/nodes.
Think like this - if you are able to make socket connection to your server then you can run Hyperledger there and connect to it using protocol buffers. And you do not care how many nodes are there, the node that you are connecting will know how to communicate with others.
gatakka
2017-01-23 17:13
Every node is a proper single point of access.

Hello, is it possible to hide (part of the) transaction details from some of the validating peers (in Fabric v0.6)? Eg., when competitors are running peer nodes in a blockchain setup, they may not be willing to reveal all the data to every other node. Whether, Fabric is suitable for such usecases?

Hi guys, I noticed this project is still considered as incubation project. Is that safe to use this for production?
gatakka
2017-01-24 10:23
version 0.6.1 is stable and can be used, but upcoming version 1 will have a lot of new features that will break backward compatibility. Good thing is that chaincode in v1 probably will be the same from user point of view, or will require some small changes.
lxnx
2017-01-24 10:24
is that any expected date for the version 1 to be release?
gatakka
2017-01-24 10:24
mid 2017

Hi! I'm a blockchain and open source development newb. Can I get some pointers on where to start in Hyperledger with regards to contributing?
I've spent the last 15 years at Amazon and Microsoft in technical program management, with a focus in devops. Documentation, user stories, and developing code for systems integration are my happy spot.
Thus far I've run example chaincodes against my local hyperledger+docker setup. What I'd like to do is develop and document more examples or demos (with a focus on how to debug and run them at scale). Would this be helpful or are there other areas that could use contribution first?
Thanks in advance.

@timskii general.batchsize for max number of trans and general.timeout.batch for time to wait for v0.6 using PBFT is specified in * .../fabric/consenus/pbft/config.yaml *
@lxnx @gattaka target date for v1.0 release is 31-March-2017 while target date for initial Docker images (alpha? beta?) is the end of this month. Anyone so motivated can download the master branch and build it themselves now, although I expect to see a flurry of changes between now and the end of the month, so don't be shocked if there are a few bumps on the road between now and then

@tom.appleyard @jwhelan your questions cannot be answered generally. The hyperledger is an umbrella project within which several blockchain frameworks are being developed. You will want to ask your question to the appropriate channel, depending on which project you're interested in: fabric, sawtooth lake, iroha (the list keeps on growing). See https://wiki.hyperledger.org/ for more details

Hello there. I am playing with a PoC using HyperLedger v0.6.. Here my scenario: I have 2 users (foo, bar) .. both have some attributes stored in the ledger, let's say FirstName and Address ... Users shouldnt be able to see attributes of others users, unless an user specifically grants access to an specific user (and to an specific attribute)... so, essentially, I am trying to *give read access of one particular attribute to another user* ..
alberto.dallaporta
2017-01-26 22:22
I've seen something similar in the car-lease-demo, where each participants has an integer representing his role stored in his ECert (https://github.com/IBM-Blockchain/car-lease-demo/blob/master/Chaincode/src/vehicle_code/vehicles.go#L15-L24)
alberto.dallaporta
2017-01-26 22:23
That is fine in an scenario in which participants are known right from start
alberto.dallaporta
2017-01-26 22:23
but.. what I can I do if an user want to grant access to multiple users during the lifetime of the blockchain?
alberto.dallaporta
2017-01-26 22:23
Should I re-generate the ECert? Is it even possible?

@alberto.dallaporta - I am not really sure about Go chaincodes. But I was trying to implement the same thing in Java Chaincode by using chaincode logic. This I was trying to achieve by getting the user details of the user who is executing the chaincode, then applying logic that whether the fetched data should be accessible to the other or not. But then I again I could not get the chaincode executor in java chaincode. Java SDK forum says that its not possible unless I implement TLS and that will not be possible until v1.0

Dear @123 / (*1 1*),
I don’t want to come across as too direct, so don’t take what I’m about to write in a bad/negative way. On the contrary:
While there is so much going on in the blockchain space these days - most of the prominent figures on these channels are well aware of these. We don’t (really) live under a rock :wink:
At the same time - we are *really making an extra effort to not get involved in/with these flaming wars* and neither try not to side with parties nor pick and choose the correct “camp” - while I can speak (/write?) only for myself, I have seen this consistently with many others members around me, regardless of employer, association or “bitcoin/blockchain” camp.
Noting that more than just that we do not have a “crypto-coin/crypto-currency”, more importantly, we all (or the vast majority of those involved or even part of it as observers, at least as far as I can see/tell) are trying to keep this fertile ground for collaboration, that is also friendly and yes - *a nice place where our time is well spent*. We share ideas, discuss or even argue (technically) about directions, possibilities, technical decisions and plans. BUT, again, we really try to avoid the exact items that you have been posting here.
While I would not call these posts “outright” spam - I do not believe that they belong here, nor do I feel that they really contribute to the “goal” of this project/effort. So in the context of Open Letters, I/many of us would appreciate it if you don’t post such things here - especially not in the #general channel. If you really feel that you “need to post/vent” :wink:, at best, I would suggest the #random channel, or so. I, personally, do check it out, randomly :wink:.
Finally (and also because most of your posts are about “bad people”, etc…), please appreciate that instead of blocking you, you getting another user, etc. - my simple request to you is: *Please help us keep Hyperledger Project’s Slack - open, friendly and productive*.
I really hope you would appreciate where this is coming from & and that you enjoy the rest of the weekend…
Amiably,
— Jonathan

Hi I am trying this fabric node example from github: https://github.com/hyperledger/fabric/blob/master/examples/sdk/node/web-app.js I have a working bluemix network running. Now I am trying to get this node example running but immediately it gives me the "throw new TypeError(kFromErrorMsg);" TypeError: First argument must be a string, Buffer, ArrayBuffer, Array, or array-like object. So I am looking at this and am translating this as an problem in the creation of the keyValueStore. Am I correct? Does anybody encoutered this issue already?

Do we have any reference data about ledger performance for Fabric 0.6 & Fabric 1.0 with consensus and CA enabled in terms of tx/s?

Hello, i have a problem with fabric v0.6. When i make a post with this json :
{
"jsonrpc": "2.0",
"method": "deploy",
"params": {
"type": 1,
"chaincodeID":{
"name":"mycc"
},
"ctorMsg": {
"function":"init",
"args":["a", "1000", "b", "2000"]
},
"secureContext": "lukas"
},
"id": "1"
}
in the json response the status.status is always "OK" .
Also when i add some parameters. Why?
Thanks

Hi @pd93 another question. Now I am constant getting some sort of a fail or time out when I try to enroll and register some one from the users array in the credentials json; ERROR: failed to register johnfoe: Error: {”created”:”@1485791222.465419951","description":"EOF","file":"../src/core/lib/iomgr/tcp_posix.c","file_line":235,"grpc_status":14} Is grpc status 14 meaning this a connection issue?
pd93
2017-01-30 15:55
@leob Have you enrolled the `webAppAdmin`or `admin` first?
leob
2017-01-30 15:55
admin
pd93
2017-01-30 15:56
and presumably set `admin` as the registrar?
leob
2017-01-30 15:58
@pd93 yes this is happening during the enroll: chain.setRegistrar(admin);

Are you 100% sure that your peers and membersrvc are all running ok?
paul.sitoh
2017-01-30 16:08
Folks, I noticed that there is not a fabric-sdk-node project. Is that now separated from Fabric v1 unlike Fabric v0.6 where the node SDK exists?
paul.sitoh
2017-01-30 16:09
I also understand that there is a separate project for orchestrating Fabric. Does anyone know if the code has been released as top level hyperledger project yet?
pd93
2017-01-30 16:12
@paul.sitoh there is indeed a `fabric-sdk-node` project (see https://github.com/hyperledger/fabric-sdk-node). The SDK is published under two packages in npm: `fabric-client` and `fabric-client-ca`. I believe these are both aimed at fabric v1 (which is about to get its first alpha release).
pd93
2017-01-30 16:12
You can ask in more detail in #fabric-sdk-node
pd93
2017-01-30 16:14
@paul.sitoh One other quick thing. If you're on fabric 0.6, the node sdk is included in the fabric repo (as is the CA - membersrvc).
In v1, these are all separated. So you'd need the `fabric v1`, `fabric-ca` and `fabric-sdk-node` repos

@abhinav.garg In the car leasing demo, there is a shared service that performs consensus for all transactions, and generally in Fabric V0.6 all transactions are validated by all participants (although of course, the consensus network might be different from the business network). With endorsers in Fabric v1 you can choose how each transaction is validated, although hasn’t been implemented in the car demo yet.

@gregg Hi Gregg..There may be more, but the ones that I have heard in actual production include global finance where they are interacting with vendors to manage dispute resolution (IBM Global Finance with other vendors), Everledger managing provenance of wine to reduce fraud (https://www.winefraud.com/chai-wine-vault/), and China Blockchain Energy which I think is fighting carbon emissions. I have seen people up here have a lot of different use case across many industries though, and there is lot of insight coming to the Hackfests by Hyperledger where you see what is being worked on (there is one in San Fran tomorrow and Thursday) Some popular use case I've heard are financial industry (things like cross border remittance and other parts of trade finance), digital property management/provenance, supply chain, and so many others.

Is there any example or document how to configure multiple host?
humblealex
2017-02-01 07:07
hey all, I am very confused with the concept of msp. Does it mean that all the credentials about a blockchain network are pre-defined BEFORE the chain creation? and all the msp configuration is contained in the generic block which the peer uses to build their own local msp. So the msp manages the certificates and signing identities for peer/orderer on the chain? could anyone elaborate on that?
humblealex
2017-02-01 07:10
does the generic block contain all the identities (certificate) for all the members on the chain?

I have three questions on the Technical aspect of HyperLedger.
1) ChainCode Registraton
2) Member Registration
3) ChainCode in JAVA
ChainCode Registration
I followed the docs at https://hyperledger-fabric.readthedocs.io and installed fabric on Ubuntu.
and was succesful in registering the chaincode with one Validating peer and one memberservice.
I tried to add three more VP to ahceive consensus.
So now i spun all the containers using docker-compose.yml(PFA) and in the shipyard i saw all the containers are started .
Then i registered the CC using the below command
"CORE_CHAINCODE_ID_NAME=cscc CORE_PEER_ADDRESS=0.0.0.0:7051 ./goods_inspection"
Got a success response as below
"14:50:11.937 [shim] INFO : error with chaincode log level: logger: invalid log level level=
14:50:11.937 [shim] DEBU : peerAddress at return point0.0.0.0:8051
14:50:11.937 [shim] DEBU : Peer address is: 0.0.0.0:8051
14:50:11.937 [shim] DEBU : peerAddress is not null0.0.0.0:8051
14:50:11.938 [shim] DEBU : os.Args returns: [./goods_inspection]
14:50:11.938 [shim] DEBU : Registering.. sending REGISTER
14:50:11.941 [shim] DEBU : []Received message REGISTERED from shim
14:50:11.943 [shim] DEBU : []Handling ChaincodeMessage of type: REGISTERED(state:created)
14:50:11.943 [shim] DEBU : Received REGISTERED, ready for invocations"
Then i deployed the Chaincode in the Shipyard vp0's console using the CLI command
“peer chaincode deploy –l go –u jim -n cscc -c '{"Args": ["init", "a","100", "b", "200"]}'”
I got the success response and expected it to be replicated across other VP’s
To check it we did the query command on another VP as VP1,VP2 “peer chaincode query –l java –u jim -n cscc -c '{"Args": ["query", "b"]}'”
But I got error “LedgerError - R esourceNotFound: ledger: resource not found”.
So to check if transaction is deployed on other peers(VP1,VP2) ,we check it using curl command and postman from chrome like
curl http://172.16.0.11:7050/chain.
Count is increased, but when tried to query the same the same error as “LedgerError - R esourceNotFound: ledger: resource not found”.
But when i register the chaincode in two nodes and register it using the below command.
"CORE_CHAINCODE_ID_NAME=cscc CORE_PEER_ADDRESS=0.0.0.0:7051 ./goods_inspection"
"CORE_CHAINCODE_ID_NAME=cscc CORE_PEER_ADDRESS=0.0.0.0:8051 ./goods_inspection"
and mapping ports in docker-compose.yaml
as
- "7051:7051" for vp0
- "8051:7051" for vp1
I noted the chaincode registration is done on two VP's and able to query the same .I dont get the "Resource not found Error"

@conroydave have you added your new users to membersrvc/membersrvc.yaml?
conroydave
2017-02-02 06:40
i hadnt, i was looking for dynamic registration
conroydave
2017-02-02 06:41
i think i was confused as my chaincode stored a data struct called users, which is a completely separate set of credentials than what my node.js app was set for
vadim
2017-02-02 06:41
it does not exist in v0.6 as far as I know
conroydave
2017-02-02 06:42
i believe it should be possible with hfc
vadim
2017-02-02 06:42
not in v0.6
conroydave
2017-02-02 06:44
ok , that is good to know
conroydave
2017-02-02 06:44
is it on the roadmap for hfc or am i just completely off
conroydave
2017-02-02 06:44
only been digging into HL for about a week, but i cant get enough. hooked
vadim
2017-02-02 06:46
hfc is for v1 and there it is possible
conroydave
2017-02-02 06:47
so in my tests ive just been blowing away the whole chain every time i push code. until v1, would the change just require a reboot of the member service?
vadim
2017-02-02 06:47
what do you mean “push the code”?
vadim
2017-02-02 06:48
deploy the chaincode?
conroydave
2017-02-02 06:48
yes
conroydave
2017-02-02 06:48
to local docker
conroydave
2017-02-02 06:48
again, i am just running modified tutorials at this point
vadim
2017-02-02 06:48
have you tried without deleting the chain?
conroydave
2017-02-02 06:49
i havent, as most of the boilerplate examples include scripts to just wipe all your containers/tags
vadim
2017-02-02 06:49
I’m not so experienced with v0.6, but I’d guess that it’s not required to remove the whole chain each time you deploy a new chaincode
vadim
2017-02-02 06:49
I guess they do it to guarantee that your chain are in known state so the example itself works
vadim
2017-02-02 06:49
but in general it’s not needed
conroydave
2017-02-02 06:51
leads to another question, all the examples include 1 membership service and 3 verifying peers.that seems like a bit counter intuitive to a decentralized system
conroydave
2017-02-02 06:52
if i were to scale my projects up - what is the balance between member services/ca’s/vps
vadim
2017-02-02 06:52
in v1 membership service is replaced by something called fabric-ca and the idea is that every institution can run its own ca as long as it is trusted by the chain
conroydave
2017-02-02 06:53
ok, by institution you mean every party that is participating in the network?
vadim
2017-02-02 06:53
yes
conroydave
2017-02-02 06:54
i am just (perhaps unjustifiably) worried about points of failure
conroydave
2017-02-02 06:54
in production - do you see most companies standing up their own services or just using IBM
vadim
2017-02-02 06:55
fabric-ca is opensourced and CFSSL-based and you can use any other CA if you like
conroydave
2017-02-02 06:55
thank you for all the insight, by the way
vadim
2017-02-02 06:56
no problem
conroydave
2017-02-02 06:57
coming from a bitcoin background - one of the most attractive features of a blockchain solution is the immutability
conroydave
2017-02-02 06:57
it seems though, with a bit of clever chaincode you make changes to data on the chain
vadim
2017-02-02 06:58
you can make changes to the state, but not to the transactions recorded on a ledger
conroydave
2017-02-02 06:58
ok, so i just have not yet implemented the revision view
conroydave
2017-02-02 06:58
but its there, given properly written chaincode
vadim
2017-02-02 06:59
well I saw a discussion somewhere in slack, so the versioning apparently based on the underlying DB they use to store the state
vadim
2017-02-02 07:00
also, chaincode operates on its own state only, so it cannot change another chaincode’s state
vadim
2017-02-02 07:01
so probably if you dont want chaincode’s state to be changed, just don’t program it
conroydave
2017-02-02 07:02
my initial demo i am working on is a education tracker for students. my implementation includes data structs for students and classes. with the student entity having an array of class id's
conroydave
2017-02-02 07:02
i am planning that when a student completes a class i just push the class ID ontop of the students completed class array
conroydave
2017-02-02 07:03
i just hope that going that route provides good history as i am overwriting that array upon each completion
vadim
2017-02-02 07:05
I’d say that if you want a history, you probably need to take care of it yourself. Not sure if it’s possible in the current implementation or let alone v0.6. But this is my opinion, I might be wrong :wink:
vadim
2017-02-02 07:05
also, how do you store that array?
conroydave
2017-02-02 07:05
hey. flailing is still learning
conroydave
2017-02-02 07:07
unfortunately i have to keep my repo private until i can get approval from cto - but it is very similar to this https://github.com/IBM-Blockchain/fabric-boilerplate/blob/master/src/build-chaincode/data/data.go
vadim
2017-02-02 07:10
no, I was just wondering how you store an array, don’t need your code
conroydave
2017-02-02 07:11
line 36 shows that its a user struct , that is mostly strings except for a single field that is an array of strings
vadim
2017-02-02 07:13
I saw it, thanks
conroydave
2017-02-02 07:14
this is the same code that got me all mixed up regarding chaincode data and authorized users for the node app
conroydave
2017-02-02 07:20

Hi everyone. I'm doing a POC on Hyperledger Bluemix platform. Followed the steps on 'Deploying your chaincode from IBM Bluemix Blockchain documentation'. There is some issue in my Golang code so it won't execute in the 'QuerySpec' step. Does anyone know how to debug the golang code that is deployed here so as to understand the problem?

The CA issuing the TCerts (Transaction CA). Shall we hop on the #fabric channel?
jonathanlevi

@viktor.nikolenko It depends. You can have a passive auditor (which has the decryption keys in advance), or an active one, which asks for them for an audit.

At the Hyperledger Event today- there was an introduction to Fabric Composer- Fabric Composer is a framework to accelerate the development of applications built on top of Hyperledger Fabric
Start from the business level; model network assets, participants, and transactions
Applications use business centric APIs to invoke transactions that create, delete, and update assets and transfer them between participants
Assets, participants, and transactions are recorded in the world state in registries
Easily integrate Fabric with existing business processes and systems of record
Emphasis on quick solution creation and business-centric vocabulary
weeds
2017-02-02 20:36
I know many of the people that are business level people that thought this would be a lot easier to program to versus direct chaincode to fabric

People at the hackfest in San Fran. , there were questions on proposed content for the alpha release for Fabric- This is the current proposed list: https://wiki.hyperledger.org/projects/proposedv1alphacontent . This is not a finalized list but what is being proposed. If you have additions or items to be removed that you want to suggest, I would recommend communicating this on the fabric-maintainers channel or the email list.
weeds
2017-02-02 23:30
Also,the following link gives you documentation that provides instructions to get familiar with the preview of the alpha: http://hyperledger-fabric.readthedocs.io/en/latest/gettingstarted/ .In those instructions, it guides you to use Docker Compose that will create a consortium of three organizations, each running an endorsing/committing peer, as well as a “solo” orderer and a Certificate Authority (CA). The network will be generated automatically upon execution of docker-compose up, and the APIs for create channel and join channel will be explained and demonstrated; as such, a user can go through the steps to manually generate their own network and channel, or quickly jump to the application development phase.

Guys,Please Help me out

2017-02-03 09:38
I have three questions on the Technical aspect of HyperLedger.
1) ChainCode Registraton
2) Member Registration
3) ChainCode in JAVA
ChainCode Registration
I followed the docs at https://hyperledger-fabric.readthedocs.io and installed fabric on Ubuntu.
and was succesful in registering the chaincode with one Validating peer and one memberservice.
I tried to add three more VP to ahceive consensus.
So now i spun all the containers using docker-compose.yml(PFA) and in the shipyard i saw all the containers are started .
Then i registered the CC using the below command
"CORE_CHAINCODE_ID_NAME=cscc CORE_PEER_ADDRESS=0.0.0.0:7051 ./goods_inspection"
Got a success response as below
"14:50:11.937 [shim] INFO : error with chaincode log level: logger: invalid log level level=
14:50:11.937 [shim] DEBU : peerAddress at return point0.0.0.0:8051
14:50:11.937 [shim] DEBU : Peer address is: 0.0.0.0:8051
14:50:11.937 [shim] DEBU : peerAddress is not null0.0.0.0:8051
14:50:11.938 [shim] DEBU : os.Args returns: [./goods_inspection]
14:50:11.938 [shim] DEBU : Registering.. sending REGISTER
14:50:11.941 [shim] DEBU : []Received message REGISTERED from shim
14:50:11.943 [shim] DEBU : []Handling ChaincodeMessage of type: REGISTERED(state:created)
14:50:11.943 [shim] DEBU : Received REGISTERED, ready for invocations"
Then i deployed the Chaincode in the Shipyard vp0's console using the CLI command
“peer chaincode deploy –l go –u jim -n cscc -c '{"Args": ["init", "a","100", "b", "200"]}'”
I got the success response and expected it to be replicated across other VP’s
To check it we did the query command on another VP as VP1,VP2 “peer chaincode query –l java –u jim -n cscc -c '{"Args": ["query", "b"]}'”
But I got error “LedgerError - R esourceNotFound: ledger: resource not found”.
So to check if transaction is deployed on other peers(VP1,VP2) ,we check it using curl command and postman from chrome like
curl http://172.16.0.11:7050/chain.
Count is increased, but when tried to query the same the same error as “LedgerError - R esourceNotFound: ledger: resource not found”.
But when i register the chaincode in two nodes and register it using the below command.
"CORE_CHAINCODE_ID_NAME=cscc CORE_PEER_ADDRESS=0.0.0.0:7051 ./goods_inspection"
"CORE_CHAINCODE_ID_NAME=cscc CORE_PEER_ADDRESS=0.0.0.0:8051 ./goods_inspection"
and mapping ports in docker-compose.yaml
as
- "7051:7051" for vp0
- "8051:7051" for vp1
I noted the chaincode registration is done on two VP's and able to query the same .I dont get the "Resource not found Error"

@smfaizalkhan you use dev mode "peer node start --peer-chaincodedev" just start it with "peer node start" and deploy it. Check that container was created and started. docker ps

smfaizalkhan
2017-02-03 11:53
bcoz when given the command docker-compose start,dockers spins off ,but as per Deploy definition ----->During “Deploy” the chain code is submitted to the ledger in a form of transaction and distributed to all nodes in the network. Each node creates new Docker container with this chaincode embedded. After that container will be started and Init method will be executed
smfaizalkhan
2017-02-03 11:53
so will it create new docker image containing Chaincode embedded in it after deploy ?
mkabanau
2017-02-03 12:31
@smfaizalkhan you are right. After deploy image will be created. I think that Container will be started after invoke or query transaction.

hi

Just 2c from my side: I am hoping that this time two things will be avoided: 1) channel bloat 2) general chaos in discussions where same topic was discussed across various channels
2017-02-03 20:25
searching into history for references without limits is definitely a plus, let's see if this is going to work out

[ ](https://chat.hyperledger.org/channel/general?msg=2sB64vcMR4sD8NMRa) @matanyahu To avoid asking questions other people have already asked is there some kind of wiki/FAQ/sticky or any kind of reference material a newcomer like me can read?

Hi All - I am fairly new to hyperledger
bgowda
2017-02-04 20:19
I managed to get java sample running
bgowda
2017-02-04 20:20
Have couple of questions, isn’t Chaincode supposed to run on peer nodes ?
matanyahu
2017-02-04 20:20
@bgowda : how did you deploy your sample?
bgowda
2017-02-04 20:21
I have docker setup
bgowda
2017-02-04 20:21
and ran the chaincode on command line and used rest command to deploy
matanyahu
2017-02-04 20:21
can you paste your rest cmd?
bgowda
2017-02-04 20:22
{
"jsonrpc": "2.0",
"method": "deploy",
"params": {
"type": 1,
"chaincodeID":{

bgowda
2017-02-04 20:22
URI (URL) - localhost:7050/chaincode
matanyahu
2017-02-04 20:24
did you deploy it from your host or did you log in to one of peers?
bgowda
2017-02-04 20:27
From my host
bgowda
2017-02-04 20:28
something like this
bgowda
2017-02-04 20:28
CORE_CHAINCODE_ID_NAME=mycc CORE_PEER_ADDRESS=0.0.0.0:7051 ./chaincode_example02
bgowda
2017-02-04 20:28
but with java..
bgowda
2017-02-04 20:29
but this process needs to keep running as it contains the chaincode (logic)
matanyahu
2017-02-04 20:29
if you type docker ps
bgowda
2017-02-04 20:29
is it possible to deploy it along with the peer that is running
matanyahu
2017-02-04 20:29
how many containers does it show you?
bgowda
2017-02-04 20:29
it has 2
matanyahu
2017-02-04 20:30
you deployed your chaincode outside of docker sandbox environment
bgowda
2017-02-04 20:30
one peer and one member-srvc
matanyahu
2017-02-04 20:30
in order to run it as a container you should deploy it like this
matanyahu
2017-02-04 20:30
peer chaincode deploy -u jim -p http://github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02 -c '{"Function":"init", "Args": ["a","100", "b", "200"]}'
matanyahu
2017-02-04 20:31
(just giving an example02 chaincode example)
matanyahu
2017-02-04 20:31
locally, from your peer
matanyahu
2017-02-04 20:31
so, do docker exec -it <name_of_your_docker_container_peer> bash
matanyahu
2017-02-04 20:32
and then peer chaincode deploy...
bgowda
2017-02-04 20:32
ok let me try
bgowda
2017-02-04 20:32
thank you
bgowda
2017-02-04 20:34
ok - does this mean what the code that needs to be deployed should be the container already

@eugenluft It seems that your a peer docker container doesn’t contain fabric project folder in $GOPATH. You should mount this folder to an appropriate place in the docker container (/opt/gopath/src/github.com/hyperledger/fabric)

how do i mount a folder to a container that is being created by the peer node itself?
ruslan
2017-02-07 13:17
@randomnerd When peer is deploying chaincode, it is creating docker container and copying $GOPATH folder to this container. Now the new container has fabric folder in his $GOPATH folder. Thats why you should have fabric folder in peer container.
randomnerd
2017-02-07 13:18

@cbf you might want to mention that there are two "login" button on the page. People should click the one on the top which says login with LFID instead of the bottom one ("login"). Normally people will fill in the LFID with password and click the bottom "login" button. I cannot remember who pointed this out first, but that helped me login to th e new tool.

Hi, I'm using v0.6 with TLS enabled. after I enabled TLS, it seems I cannot access to PEER node via REST anymore although I installed the certificate on the browser. Is this the normal behavior? Could anyone suggest on this? Thanks
